Major Don West is the pilot of the Jupiter 2. Don's military training has proved useful in resolving a number of tense moments. He is also adept at overpowering aliens with his strength, but despite this he has suffered injuries more often than anyone else in the crew. This may be partly due to the fact that he has a susceptibility to concussions which makes it easier for him to fall unconscious if he hits his head hard. Don has a varied rapport with the others on the mission. If it were up to Don, Dr. Smith would be left behind. Don respects Professor Robinson, but sometimes questions his judgement. He is obviously attracted to Judy, but his feelings for her are often implied rather than overt. Despite being a top-notch pilot, Don seems to have a problem avoiding crash landings. Don often reveals a violent temper that must be occasionally reined in by Prof. Robinson. During the latter part of the series, Don showed signs of mental instability. Killing Don off in the unmade 4th season was considered, according to fan rumour.

Basic Information

  • Full name: John Sims Robinson
  • Birth date: January 14, 1957
  • Birth place: Taos, New Mexico, USA
  • Height: 6 feet, 3 inches
  • Weight: 200 pounds
  • Eyes: Hazel…Hair: Dark brown
  • Hobbies/interests: Sports, especially football, fencing, boxing

The original pilot introduced him as Dr. John Robinson, Professor of Astrophysics at the University of Stellar Dynamics, and is heading the expedition.

The Reluctant Stowaway” script describes John as having wide-set, intelligent eyes. His brilliance does not offset his humanity. He is a very kind and caring human being. John went to school with a boy whose father owned a carnival. The boy taught him how to do the old shell game trick. This is mentioned in “Curse of Cousin Smith.”

John Robinson was the fifth child of a lower income family. His high intelligence, good looks and athletic ability helped him to overcome his economic hardships.

In school, John was always at the head of his class academically. He also shone on the football field, becoming the youngest quarterback ever at East Side High School during his sophomore year.

Academics remained his primary interest, however, despite several lucrative offers from colleges that wanted him to play on their football teams. By working part-time and obtaining academic scholarships, John was able to enroll at the California Institute of Technology (CIT) in 1976. The school offered a combined degree program in Astrophysics and Planetary Geological Sciences, which combined his keen interests in space and geology.

Although popular, John had never dated much. While at CIT, though, he met a beautiful and brilliant student named Maureen Tomlinson. Despite hectic schedules, the two found time to be together and were soon virtually inseparable. During the summer break after their first year in college, they were married on June 10, 1977. Maureen's sister, Colleen, invited them to live with her in Los Angeles while they finished college, and they did so for the next four years.

John decided to stay for a fifth year at CIT in order to earn his Master's degree in Astrophysics and Applied Planetary Geology. He graduated with honors in 1981. His first job was as an instructor of Astrophysics at the University of Taos (New Mexico). While working there, he continued his education and received a doctorate in 1985. He won a number of awards while at the school for outstanding teaching ability and leadership, including the prestigious Zane Morris award.

While all of this was going on, the Robinson family was growing. Daughter Judy was born on February 26, 1978. The Robinsons moved to their own home near Santa Fe, New Mexico. Penny was born on September 8, 1985, and Will was born on February 1, 1987.

After seven years of teaching, John was restless. When Alpha Control offered him the opportunity to work on a new joint program with the university to study the adaptability of humans to life on alien planets, he immediately accepted, although it did mean that he had to spend some time in Houston, Texas, where Alpha Control was building a gigantic scientific and training facility.

John (known as "Professor Robinson" at Alpha Control) was soon deeply involved in the program to develop the Deep Thrust Telescopic Probe series of interstellar spacecraft. These ships were launched in December 1988 and showed definitively that Alpha Centauri had two planets, Delta and Gamma, capable of supporting human life. One of them, Gamma, was found to be ideal for colonization.

John was next given a position with Alpha Control's Colonization Studies Division. His enthusiasm for the colonization program rubbed off on Maureen. Despite misgivings about the dangers of space flight, she eventually agreed with John to volunteer the family for the first colonization mission.

Alpha Control announced in February 1993 that it would begin taking applications from families for the Jupiter 2 mission. Four months later, it was announced that the Robinsons would be the first family in space. They spent the next four summers training for the mission, and left Earth on October 16, 1997.

Guy Williams portrayed John Robinson in the original series. John Robinson was voted one of the most popular fathers in television history by T.V. Guide.

Basic Information

  • Full name: Judith Elana Robinson
  • Birth date: February 26, 1978
  • Birth place: Los Angeles, California, USA
  • Height: 5 feet, 4 inches
  • Weight: 108 pounds
  • Eyes: Blue…Hair: Blonde
  • Hobbies/interests: Acting, singing, popular music and "sleeping in late"

The original pilot introduces Judy as: Judith, aged 19, who heroically postponed all hopes in the musical/comedy field for at least two centuries.

Judy Robinson was a backward, shy child who had trouble making friends, partly because her parents were often away as they pursued their scientific careers. She spent a few years living with her Aunt Colleen in Los Angeles, where she became very close to her cousin, Joan—"a relationship that continued up to the day of the Jupiter 2 launch."

Judy became better adjusted as she entered her teenage years, and attracted quite a few boys. Her mother refused to let her date until age 16, however.

During her high-school years, she spent her summers at the United States Space Corps Training Center in Houston, Texas, where, in addition to studying academic subjects, she learned about survival in space, the operation of Jupiter 2 equipment, and spacewalking.

Although above average in intelligence, Judy did not inherit her parents' superior intellect. In her own words, she "never really cared much for school," but found she was talented at acting, singing and dancing. She planned to pursue a career in one of those areas.
Debbie and Judy
Her plans had to change when the Robinson family was chosen for the colonization mission. Always emotional and slightly rebellious, Judy didn't want to join her family on the mission at first.

She changed her mind when Major Donald West was selected to be the Jupiter 2's pilot. They hit it off immediately because of their complementary personalities: Both are impulsive, but Judy is compassionate and caring, while Don is, in her father's words, "a real hothead." Though she once complained to her mother that she didn't have more men to choose from, Judy and Don have become very close while lost in space.

  • Birth place: New York City
  • Height: 5 feet, 5 inches
  • Weight: 128 pounds
  • Eyes: Blue… Hair: Auburn
  • Hobbies/interests: Cooking, hydroponics, gardening

In the original pilot episode Maureen Robinson was introduced as: Dr. Maureen Robinson; a distinguished biochemist from the New Mexico College of Space Medicine.

Maureen Robinson was born the second daughter of James and Margaret Tomlinson. Her father was the founder and owner of Tomlinson Engineering Corporation, an aircraft navigation systems design firm.

She was educated at a private school for gifted children. Maureen had a normal childhood until her parents were killed in a plane crash in 1966. Her older sister, Colleen, who lived in Los Angeles, then became Maureen's legal guardian. Because of the tragic death of her parents, in later years, she would feel strongly about the well-being of her husband and three children, sometimes to the point of being over-protective.

Maureen graduated from high school in 1976, and then enrolled at the California Institute of Technology. She received her bachelor's degree in chemical engineering in 1980. While in college, she met a young student from New Mexico named John Robinson. They were married in 1977, and their first child, Judy, was born in 1978.

After college, Maureen worked at the New Mexico Institute for Space Medicine. In 1985, with the birth of Penny, she left her job to become a full-time mother and housewife.

After a while, she went back to school to obtain her master's degree, which she completed in 1991. She then began to work on a doctorate in biochemistry, which she received from the University of Taos (New Mexico).

She was at first shocked when John proposed the idea of becoming the first family to colonize Alpha Centauri. Though still reluctant, she finally consented, and John submitted their application to Alpha Control in March of 1993. Three months later, the Robinsons were chosen to be "the first family in space." They spent the next four summers in training at the United States Space Corps training facility in Houston, Texas. Maureen and her family left Earth on October 16, 1997.

  • Full name: Penelope Roberta Robinson
  • Birth date: September 9, 1985
  • Birth place: Santa Fe, New Mexico, USA
  • Height (at launch): 4 feet, 9 inches
  • Weight (at launch): 75 pounds
  • Eyes: Hazel… Hair: Dark brown
  • Hobbies/interests: Zoology, classical music, literature

The original pilot describes Penny as aged 11, with an I.Q. of 147, and zoology as a hobby.

With the arrival of second daughter Penny in 1985, Maureen Robinson left her job at the New Mexico Institute for Space Medicine and became a full-time housewife, a position she found fully satisfying.

Like all of John and Maureen's children, Penny Robinson is talented and intelligent. By the time of the Jupiter 2 launch, when she was 12 years old, she had advanced to the 10th grade and had an I.Q. of 147.

Shortly after the Robinsons were chosen as the first family in space, Penny joined the newly formed Space Scouts. This was a nationwide program that Alpha Control had set up to recruit young people for future colonization missions. Penny's leadership abilities were proven when she was soon elected president of the Santa Fe chapter.

Penny has some tomboyish characteristics, probably due to her closeness to her brother Will. She also has a tendency to let her imagination run out of control. Her parents sometimes have difficulty telling whether she is relating fact or fantasy. This got her into some trouble during her year on Priplanus.

An animal lover, Penny adopted a Bloop—a small, ape-like creature—as a pet shortly after the family reached the planet. She named it Debbie.

Another aspect of Penny's character is her outgoing, friendly personality, that made her very popular with Alpha Control instructors and employees. As Alpha Control's psychological tests predicted, Penny adjusted very well to the stresses and pressures of space travel.

Penny is a deeply thoughtful young girl, growing up on the spaceship without companionship of her own age. She likes to be alone and lives quite actively in her imagination. She is brave and cheerful, though sometimes curt or sarcastic with her younger brother Will. She continues her studies on the Jupiter 2, and hopes eventually to become the foremost authority on extra-terrestrial life.

The RobotEdit

Race The Robot
Also Known As B9
Affiliations Zachary Smith
Will Robinson

The Robot (a B-9 Class M-3 General Utility Non-Theorizing Environmental Control Robot) was a character in the television series Lost in Space. Known and addressed simply as "Robot", his full designation was only occasionally mentioned on the show. Occasionally the Robot was addressed with the names of B-9 and the Robinson Robot. Other names for the Robot were Rodney and his creator, Robert Kinoshita, called him Blinky.

History Edit

Although a machine endowed with superhuman strength and futuristic weaponry, the Robot often displayed human characteristics such as laughter, sadness, and mockery, as well as singing and playing the guitar. The Robot was performed by Bob May in a prop costume built by Bob Stewart. The voice was primarily dubbed by Dick Tufeld, who was also the series' narrator and Jorge Arvizu for the Spanish dubbing. The Robot was designed by Robert Kinoshita, who also designed Forbidden Planet's Robby the Robot. Robby appears in Lost in Space episode #20 "War of the Robots" and in episode #60 "Condemned of Space." The Robot did not appear in the unaired pilot episode, but was added to the series once it had been greenlit. Initially, the bellows-covered legs were articulated and moved separately by the actor inside, but the metal edges inside the suit cut actor Bob May's legs so changes were made. The legs were bolted together, and the robot was pulled along by a wire instead of walking as it had done before. A new lower section was constructed with the legs cut off at the knee. This shorter suit was used to film close-ups or when the Robot was standing behind something that hid the actor's legs protruding out the bottom. This version of the suit was informally referred to by the cast and crew as "the Bermuda shorts."

Features and Abilities Edit

Robot B-9 consisted, from top down, of a glass bubble sensor unit with moving antennae; a fluted, translucent ring collar (actually an arrangement of shaped ribs through which performer Bob May could see); and a cylindrical, rotating trunk section with extending bellows arms that terminated in red mechanical claws. The trunk section had controls, indicators, a removable power pack and a signature chest light that illuminated in synchrony with the Robot's speech. May had a key inside the suit located in the left hook that he would tap in time with his speech to illuminate the light, resulting in some scenes where one of the claws can be seen moving in time with the light. Below the trunk were the bellows legs that were understood to move with some agility but which were rarely seen on camera to move separately due to real-world practical limitations, and tarapezoidal tread-tractor units at the bottom of each leg. These normally worked as a single locomotive device, but they could also function as individual feet. The leg and tractor sections could apparently be readily detached, allowing the Robot to be positioned in the rear of the chariot, although the actual disconnect operation was depicted only once. According to the series, the Robot possessed powerful computers that allowed him to perform complex calculations and to deduce many facts. He had a variety of sensors that detected numerous phenomena and dangers. He was programmed with extensive knowledge on many subjects, including how to operate the Jupiter 2 spaceship (although in the episode "The Hungry Sea" the Robot states categorically that it is not programmed to pilot the ship). His construction allowed him to function in extreme environments and in the vacuum of space. He was extremely strong, giving him utility both in performing difficult labor and in fighting when necessary. Moreover, his claws could fire laser beams and, most frequently, a powerful "electro-force" that was similar to arcing electricity. In one first season episode, Dr. Smith was seen to remove the robot's programming tapes, which resemble a small reel of magnetic tape, from a hatch below the robot's chest panel.

After Lost In Space Edit

Two versions of the robot were used during Lost in Space filming, a "hero robot" costume worn by Bob May, and a static "stunt robot" prop that was used for distant or hazardous shots. Both versions fell into disrepair after the series but they have since been discovered and restored. The "hero robot" is privately owned by TV and film producer Kevin Burns who commissioned a replica in the early 1990s for touring and conventions. The "stunt robot" is in storage at the Science Fiction Museum and Hall of Fame in Seattle, Washington. Like Robby the Robot, the B-9 Robot prop costume was re-used on at least one other show. On the Saturday morning children's show Mystery Island, it was modified to create the primary character P.O.P.S. It had different domes, a different color scheme, and an added rectangular skirt of gold-colored tubes covering the rubber bellows legs and base. Full-sized replicas of the robot are available commercially. Other versions have been built by hobbyists around the world who have built at least 15 detailed full-size replicas of the Robot.

Extra Information Edit

Was the Robinsons' trusted Robot more than he appeared to be? Perhaps even extraterrestrial in origin? There are some hints at the use of extraterrestrial technology in the construction of the Robot, but many of the instances can be more simply explained.


-In "War of the Robots," the Robot knows what a robotoid is and seems to know that they are dangerous right from the start; he even seems to be able to track it a bit at the beginning of the episode.
-The Robot seems to know right away that the masked John Robinson is not the alien himself in the last half of "Follow the Leader." He also knows this alien is a spirit.
-In "The Ghost Planet,” the alien machines are well aware of the existence of the Robot and he doesn't seem too surprised by them. They seem to know each other or at least of each other's existence.
-In “The Ghost Planet,” the Robot also knows that the missile fired by the planet is hyper-atomic.
-In “The Golden Man,” the Robot knows the ratings of alien minefield bombs.
-In “A Visit to Hades,” the Robot recognizes Morbus as an alien right away.
-In “Hunter's Moon,” the Robot knows a bit too much about Megazor and his culture and that Earthlings are not natural enemies of the Zon culture.
-In "Flight Into the Future,” the Robot seems to know the illusions are not real.
-In “A Day at the Zoo,” Robot seems to know what Farnum's alien flower trap will do.
-In “The Anti-matter Man,” the Robot knows quite a lot about the anti-matter universe.
-In “Fugitives in Space,” the Robot knows Space Law.

Rebuttal: All of the above can be explained by the Robot's use of his sensors, superior analytical ability, or the application and extrapolation of knowledge programmed into him. The Robot's familiarity with alien cultures may be attributed to 'off-screen' communication.


-In "A Change of Space," the Robot can communicate with the alien.
-In “Wild Adventure,” the Robot can translate for Athena.
-In “The Girl from the Green Dimension,” the Robot can translate for Urso.
-In "Kidnapped in Space,” the Robot can communicate with the alien machine and operate on it.
-In “Condemned of Space,” the Robot communicates with the alien robot.
-In “Castles in Space,” the Robot translates for the Princess.

Rebuttal: In “Invaders from the Fifth Dimension,” the Robot reveals he can 'read minds' by translating the electromagnetic waves of human thought back into words; this could also apply to sentient alien species. In several episodes, the Robot states that an alien language (and this applies to alien machines as well) is based on mathematical principles; since mathematics is broadly considered a 'universal language,' the Robot is able to use it to establish communication.


-In "Return from Outer Space," the Robot can work the matter transfer unit.
-In “Wreck of the Robot,” the aliens know how to take the Robot apart without damaging him.
-In “Revolt of the Androids,” the Robot can repair IDAK Alpha 12.
-In “The Space Primevals,” the Robot can make things vanish and reappear.
-In “Junkyard in Space,” the Robot's parts are compatible with the Junkman's.

Rebuttal: If humans can figure out alien technology, even if only by trial and error, the Robot should be able to do so as well, and more quickly too. The instances above must also be considered in the light of the points raised above: the Robot's use of his sensors to gather information, his superior analytical abilities, and the knowledge already in his possession from which he can extrapolate.

Not Really a Problem

-In “The Dream Monster,” the Robot can beat Raddion.
-In "Trip Through the Robot," despite having had put the Robot together at least twice, Will, Smith, Don, and John do not recognize a lot of the areas and components; is that because they alien or just different due to the enlargement?
-In "The Challenge," the aliens don't seem too worried about the Robot.
-In “Princess of Space,” the Robot was used as a hiding spot for the alien baby princess by her nurse at some point before the events related in the episode "The Reluctant Stowaway."

Rebuttal: The matter of extreme enlargement is sufficient to explain the Robinsons' puzzlement in “Trip Through the Robot.” The points raised in “The Challenge” and “The Dream Monster” do not speak either for or against an alien origin for the Robot. The real problem raised by “Princess of Space” is not that there may be alien technology in the Robot. What is in the Robot is simply a tape that has been hidden; it is not a functioning part of his mechanism. The real question here is how the alien nurse managed to secrete the tape there before the Jupiter 2's lift-off and why she chose the location she did.

The Only Unresolved Mystery

-In "The Mechanical Men,” it is suggested that alien technology may have been used to create the little alien robots as well as the Robot; it cannot be just coincidence that the Robot and the tiny robots are exactly the same in so many ways.

Comment: In “The Mechanical Men,” the Robot himself hints that itheknows the explanation to the unexplained similarity, but this is never revealed. This thus remains the only insoluble mystery regarding the origin of the Robot.

If that's not enough, the Robot just seems to know a bit too much about all the alien cultures encountered, enough to make one wonder. At times, he seems to surprise the family, even Will and John, with what he knows, and even Smith is at times surprised to find out what Robot knows and can do.

  • The Robot, Will says in 1998, was built only two and a half years ago in "Trip Through the Robot." He develops more in "War of the Robots" and later both Will and John admit that the Robot is not quite a machine but something between a machine and a man. The Robot has certainly developed human emotions of a sort by "The Wreck of the Robot," and would miss Smith and Will if either left or if he left either of them. This is seen in "Rocket to Earth" and "The Mechanical Men."
  • The Robot tried to convince himself he was not jealous of Verda (which he was but he did vote to keep her with the Robinsons).
  • The Robot starts acting more like Dr. Smith in the second season, picking up some of his phrases such as, "Hey, wait for me!" in "Treasure of the Lost Planet," as well as some of Smith's fear displayed in "The Toymaker," when Robot says, "I feel sick."
  • The Robot, in "Treasure of the Lost Planet," also says, "The final indignity", another Smith phrase, when Smith used him as a roulette wheel. The Robot also developed a sense of humor in "War of the Robots—" "bad, very bad," and "Excuse me, I think I'm going to be sick!" and in "The Prisoners of Space" in response to Smith's bragging that he has only a few minor faults.
  • In "The Space Primevals," the Robot also admits to Will that Dr. Smith's "timidity can be infectious." This happened after Will noticed Robot sounded a lot like Dr. Smith after warning Will that their trip might be fraught with danger.
  • The Robot claims in "Kidnapped in Space" that he took two semesters of medical training at the Institute of Cybernetics (Don says two years of training). He graduated first in his class. This was all before he became interested in Space Exploration and switched his major (?)! He also tells Will that if he can reactivate his programming tapes on medical knowledge, he can do them proud by operating on the alien clock leader of the Xenians.
  • The Robot's relationships with Will and Smith is more complex than they seem. He has a love-hate relationship with Dr. Smith going on in all the seasons, but also admits that Smith is a great, decent human being and a credit to their expedition. The Robot also admits that Smith is his mentor and that he has a deep affection for Dr. Smith, yet Smith continues to treat him as badly as he did in "War of the Robots" (for which mistreatment Dr. Smith must polish the Robot for two weeks).
  • Smith continues to be cruel or unthinking in "Trip Through the Robot," but manages to try to start the diode timer for Will, seeing how much the boy cares. In "Rocket to Earth," Smith admits the lovable old ninny did have one or two good qualities about him. During the same episode the Robot says, "Oh, Dr. Smith, don't go. We need you."
  • The Robot was staying with Smith in "Cave of the Wizards." He carries Smith on his treads in the same episode and sometimes offers to do the same in others.
  • The Robinsons, Don (who has a pretty good knowledge of the Robot when he is normal size), and Smith probably have taken parts from other computers and robots to use in the Robot. They may have copied tapes from other robots and alien devices into their Robot. This could explain why the Robot knows so much more about alien law and such starting from late in the first season, in the second season, and much more in the third season. Such parts or sharing of information could have come from the robotoid in "War of the Robots," and the alien robots in "The Ghost Planet" may have shared their tapes with the Robot. In addition, the Robot may have shared information with the robot guard and used spare parts from the Verah Castle in "Condemned of Space."
  • Don, Will, and John put the Robot back together in "The Wreck of the Robot." Smith puts him back together in "My Friend, Mr. Nobody." Maureen and Judy work on him in "The Golden Man."

  • Height (at launch): 4 feet, 3 inches
  • Weight (at launch): 60 pounds
  • Eyes: Hazel… Hair: Red
  • Hobbies/interests: Geology, electronics, playing the guitar and singing

The original pilot described Will as having recently graduated from the Camdoe Canyon School of Science at the age of 9 with the highest average in the school's history.

By the age of 5, people were already calling Will Robinson "the little genius." At the age of 6 (when he was already in the third grade), he dismantled the family's VCR, then put it back together again in perfect working order—much to his family's amazement. His I.Q. at the time of the Jupiter 2's liftoff was 182, and he had just graduated from the Santa Fe High School of Science.

On Earth, Will's extraordinary intelligence made him something of a misfit. Neither children his own age nor the older students with whom he attended school understood him very well. He often tried to take on adult responsibilities, but adults had trouble taking him seriously.

Will's attempts to make adult decisions were still creating problems after leaving Earth, as he often endangered both himself and his family by going off on his own without John or Maureen's permission. On the other hand, his intelligence and common sense saved the space pioneers and Dr. Smith, with whom he has developed a deep friendship, on many occasions.

The Ballad of William Robinson03:08

The Ballad of William Robinson

Among Will's chief characteristics is his intense curiosity. This often gets him into trouble, as when he set off on his own to explore a seemingly derelict alien ship the Robinsons encountered soon after the family became lost in space. He is also intensely loyal, even to those (like Dr. Smith) who don't always deserve it. Will is very devoted to the Robinsons' B-9 environmental control robot, even though it once tried to kill him, and has used his skill with electronics to keep the Robot functioning at a high level. On a personal level, Will is sometimes sarcastic, but he is always polite. Perhaps because he is the youngest member of the crew, Will seems to have adapted better to the uncertainties of life in space better than anyone else on the Jupiter 2. Will's constant companions are Dr. Smith and the Robot. Will says that he and the Robot are like brothers.

  • Height: 5 feet, 11 inches

The episode "The Reluctant Stowaway" identifies Dr. Zachary Smith as an intergalactic doctor of environmental psychology. He was the United States Space Corps' staff psychologist and environmental expert prior to his unexpected departure from Earth. He was an agent for an enemy foreign government.

Prior to the launch of the Jupiter 2 from Earth, Dr. Smith reprogrammed the Robot to destroy the ship eight hours after departure. While making last minute adjustments to ensure a successful sabotage, Dr. Smith subdued a guard on duty aboard the spacecraft, possibly killing him. He was later trapped aboard the Jupiter 2 while attempting to reactivate the Robot which had been shut down by a technician. The crew were protected from the effects of lift-off in their state of suspended animation, but Dr. Smith was forced to endure it fully conscious. The ship is thrown off course by Dr. Smith's additional weight and becomes hopelessly lost. It was later revealed in the series that this course deviation prevented the destruction of the Jupiter 2 in a violent meteor shower soon after lift-off.

Dr. Smith spent his earliest years in lower Manhattan, New York City, until his parents were killed in a boating accident. The young Smith then went to live with his Great Aunt Maude and Great Uncle Thaddeus in Marietta, Georgia. Aunt Maude was the matriarch of the Smith family, and she raised Zachary with a stern hand. In his own words, the doctor admitted that sometimes he had 'a tendency to be lazy,' but the determined lady pressured him into obtaining reasonable grades at school. Through her considerable social connections, she managed to obtain Marshall scholarships for the entrance of both Zachary and his cousin Jeremiah to Oxford University. At Oxford, Smith worked on his degree in psychology, and became the Grand Master of the Oxford Chess Society for three years in a row. He later entered Harvard University where he earned his doctorate. After graduation, he joined the United States Air Force.

Over the next 16 years, Smith had an exceptional career as a military psychologist, and was stationed at a number of U.S. military bases in the United States and Europe. He was promoted to Colonel in 1995, and then transferred to the recently formed United States Space Corps. The USSC sent him to its Houston, Texas, training center, where he went through an extensive paramedical retraining program. The training combined his expertise as a psychologist with a new branch of medicine dealing with the mental stress and physical pressures that would be put on future space colonists. Only about two dozen people in the world specialized in this field, known as Environmental Space Psychology.

Dr. Smith was involved in the artificial intelligence programming of the Jupiter 2's Series M-3, Model B-9 robot. He reviewed the psychological fitness of potential pilots for colonization missions, as well as volunteers for the missions, including the Robinson family. Smith performed the final stress-analysis examinations of the Robinsons before they left Earth.

The above information was taken from the standard USSC personnel file, but there was another side to Zachary Smith, which Alpha Control officials pieced together after they began to suspect that Smith's disappearance at the time of the Jupiter 2's ill-fated launch was more than a coincidence.

Smith's Aunt Maude's husband, the late Thaddeus Smith, was an eccentric, superstitious and bizarre person who had a bad influence on young Zachary and his cousin Jeremiah. It was discovered that Smith's high grades were largely due to cheating and bribery, and that his entrance to Oxford was due to a bribe paid by his prosperous Aunt. Zachary and Jeremiah hadn't wanted to attend college in England, but Aunt Maude, an Oxford graduate herself, convinced them by promising that whoever graduated first would inherit her fortune. Within six weeks of entering Oxford, Jeremiah was expelled for gambling and returned to Georgia. Shortly thereafter, Aunt Maude died mysteriously. Jeremiah disappeared, amid rumors about a UFO abduction.

Under the circumstances, the terms of Aunt Maude's will were revised so that the last surviving Smith cousin would receive her fortune. Zachary, without the comfortable income he had become accustomed to, dropped out of Oxford for a while, and traveled around Europe as a common drifter. During this period, he was apparently contacted by an intelligence agent of a country that considered itself an enemy of the United States and was offered a substantial sum of money to act as a future plant within the United States Air Force. Smith returned to the United States with a degree from Oxford (now known to be forged). His intelligence contacts saw to it that he was admitted to Harvard.

Smith later used his position as a military psychologist to learn classified information from his patients using hypnosis and other means. His cover was obviously a good one, for while Smith never made many friends with his caustic personality, he did develop an excellent reputation as a doctor, and no one ever suspected his true purpose within the military. During his military career, Smith's tastes became very expensive, and he pressured his intelligence contacts to get him a position that would gain him greater income. They installed him as an operative within the USSC, along with several other operatives already there, collectively known by the code name Aeolus Umbra. Note: Aeolus was the keeper of the winds in ancient Greek mythology; umbra is the Latin word for shadow or shade, and, by extension, ghost or spirit.

The destruction of the Jupiter 1 in 1993, which was officially attributed to a fuel system malfunction, was probably due to sabotage by these agents. Although Smith was not involved in that disaster, he undoubtedly had help from other agents within the Space Corps with his attempt to destroy the second colonization ship.

After the launch of the Jupiter 2 on October 16, 1997, Smith's behavior became increasingly bizarre and childish, according to logs that John Robinson left on interstellar fuel barge F-12, which were later retrieved by Alpha Control. Within a year, the enormous stress of his space voyage, which has included contact with numerous hostile aliens, had transformed Smith into a mere shell of his former self.

The final paragraph of the Alpha Control profile of Smith reads as follows:

Now that the investigation into Col. Smith's background has been concluded… the decision is up to the President as to whether Smith should be tried in absentia for murder, attempted murder, espionage, etc. Considering the negative publicity such a trial would receive, the current mental condition of the man, and the simple fact that Smith will probably never return to Earth to have whatever sentence he received carried out, we can only recommend that the man not be brought to trial unless he returns to his home planet.

Personality Change Edit

The radical change in Dr. Smith's character is attributed to the magnetic fields generated by the ship's propulsion device, which can, and will, produce permanent brain damage in any life forms not protected by the freezing tube during full-powered liftoff. As could be predicted, the use of 100% of engine power when leaving Earth's atmosphere affected the unshielded doctor's mind. Within two or three weeks the behavior of the colonel grew more and more bizarre, and within a year, his exposure to the magnetic fields that propelled the interstellar ship would leave the man a shell of his former self. The Robinsons went through vigorous testing when they were chosen to become the first pioneer space family; Smith, however, received none of this testing. Like astronauts of today, the Robinsons would have had to pass many psychological tests to ensure their fitness to serve aboard a long-duration mission. Smith had none of that testing, and a good case could be made that all the stress of the mission on an untrained person, not to mention the numerous dangers with which Smith came into contact on Priplanus, finally caused him to begin losing his mind little by little. Smith was also a xenophobe who was constantly being forced into contact with aliens. This alone could also have caused a personality change.

Additional Information Edit

Little is known of Dr. Smith's background. We know he had a great-aunt Maude and cousin Jeremiah Beauregard Smith ("Curse of Cousin Smith"), a great-uncle Thaddeus, possibly an uncle Thaddeus, an aunt Matilda (all three from "Ghost in Space").

In "Blast Off into Space," Dr. Smith claimed that his (great-)uncle Thaddeus discovered the Comstock Lode all by himself (the Comstock Lode was discovered in 1859). He also mentioned that his great-great-grandfather was a forty-niner.

As a youth, Smith spent many summers on his Uncle Thaddeus's farm where he won first prize at the County Fair but not for the tomatoes (and the Robot seems to know this in "The Golden Man"). Aunt Maude died under mysterious circumstances, Smith was at her bedside; Jeremiah gave her medicine shortly before she died but a coroner's inquest found him not guilty of foul play.

Maude left a will that gave the last remaining Smith her fortune. The last time the cousins (there were ten of them at that time) tried to settle this peacefully, Jeremiah tells John (and he could be lying) it looked like a bloodbath that made the St. Valentine's Day Massacre seem like a picnic.

On his mother's side the name is Ruthven—at least partly Scottish. One of the Smiths was a Ruthven who, in 1497, bore witness against Hamish Rhu-Glamis, ninth Laird of Glamis. Hammish was subsequently executed for high treason against his liege lord and master James Steward, king of Scotland (from "The Astral Traveler").

In "The Galaxy Gift," Smith claims to Penny that he has an aunt who lives on Knob Hill, not far from San Francisco's China Town. This might be an aunt on his mother's side, a surviving Smith not known to anyone else, or perhaps a figurative aunt (close friend to the family?) or someone else entirely—a great aunt maybe.

Smith also has a gambling addiction. A look-alike for Dr. Smith, the space outlaw and desperado Zeno of Casseopia, once made an illegal visit to the planet Earth. Smith wears a large ring on his left hand. He also seemed to have his grandfather's timepiece on him or with him since "The Reluctant Stowaway" all the way to "The Space Primevals" where a caveman alien guard snatched it from him.

Dr. Smith always loved food and lazing about. Smith also recalls walking hand in hand through nature's wonderland on nice days on Earth but he also claims to abhor nature ("The Great Vegetable Rebellion)—it always makes him sneeze (and he does so in "Deadliest of the Species" and "The Dream Monster" cliffhanger into "The Golden Man" where Penny has flowers near his nose).

Smith claims to have been a medical doctor, a psychologist, a psychiatrist, an expert gourmet as well as a doctor of environmental space psychology. He claims to have known a famous British female cook.

Smith gave teachers apples when he was in grade school, snitched on fellow school mates (such as Johnny Sorenson), played the ukulele (which he used to hide stolen test papers in when in high school and college), sold stolen test answers for 100 dollars, once wore a sportsman shirt with a C on it, and a baseball cap.

Smith may have taught NY Dodger baseball player Sandy Kofax the dipsy doodle throw (which he professed he did to Will and Penny by the time of the cliffhanger before "Rocket to Earth"). Smith seemed to disdain the mention of baseball in "Wild Adventure" ("Oh yes, THAT."). He also professes to have been taught a thing or two about pitching from Satchel Page, a Cleveland Indians baseball player who had struggle up in the league because he was black (this was just after Jackie Robinson). Smith also mentions Joe DiMaggio, Ted Williams, and Babe Ruth. All this despite Smith claiming to dislike sports in "The Deadly Games of Gamma 6"—"they seem so healthy."

Smith hit and may have killed a guard on the Jupiter 2 in "The Reluctant Stowaway" (in the original script it was a stun needle on his ring or some kind of poison), was fairly selfish and evil minded in most of "The Reluctant Stowaway," "The Derelict" (where he kills or injures a few of the bubble aliens—which he feels sorry for (somewhat) in "Prisoners of Space"), and "Island in the Sky" (where is at his meanest—forcing Don and Maureen to abandon John on the planet, using the Robot to threaten to crush their skulls, and sabotaging not only John's rockets but the Jupiter's as well). He did lament having to do away with Will, a somewhat fit companion in all this nightmare.

After the crash landing, he plots with the Robot, who he has given orders to check on his safety every hour on the hour, to kill all the others with the exception of Major West. When they learn what they needed to know from West, he, too was to have been eliminated.

Smith regretted only having to kill Will. Smith was a bit more open minded in "There Were Giants in the Earth" and "The Hungry Sea" even though still hoping the Robinsons would be killed as they ventured across the planet by lightning, earthquakes, monsters, deep freezes, and excessive heat. Yet, he warns them, not once but twice, feeling perhaps that he needed human companionship—the Robot was still pretty mechanical and dullard-like.

Smith was selfish in "Welcome Stranger," continued to spy on Penny in "My Friend, Mr. Nobody," offered Will up to the "Invaders from the Fifth Dimension" in what must be one of his most evil acts, and continued to plot against the entire group in "The Oasis."

In "The Oasis" it is apparent that John, Maureen, and the three kids have begun to feel something like respect and even love for Dr. Smith and it could also be that the fruit Smith ate, affected his mind for a bit. He certainly plots the end of the others when he thought he was going to die.

He was not too nice to Will in "The Sky Pirate" and "The Questing Beast" offering Will up as a hostage in both and not caring if the Robot killed Tucker or accidentally hurt Will in "The Sky Pirate."

He did seem to care that Penny would be hurt in "My Friend, Mr. Nobody." He spied on Judy and Penny in "The Magic Mirror" since his greed made him want the full length alien mirror the two girls were propping up for use. Smith once called Penny Penelope when he thought she was using this mirror to trick him.

He once told Penny her garden would whither and die if the Robinsons left him on Priplanus ("Attack of the Monster Plants) and in the same episode used Judy's vanishing as blackmail on the family so that Don would take him back to Earth.

He also spied on Judy and Don as well as John and Maureen in "The Keeper." Getting back to Earth, riches, power, food, and self were Smith's chief obsessions. He plotted many a time to steal some alien or visitor's spaceship ("The Keeper," "The Sky Pirate," "The Questing Beast," "Rocket to Earth," and many, many more).

Smith may have not admitted it often ("your family my boy, not mine" in cliffhanger of "Wild Adventure" into "The Ghost Planet") but he may have considered himself one of the family by the time of "The Girl from the Green Dimension." Smith was always cautious of the aliens and often misjudged the good ones—such as in "The Sky Is Falling" and "Wish upon a Star" and was good at getting the others or some of the others to his way of thinking ("The Sky Is Falling" where he has Judy and Penny thinking he is right and has Don so on edge that Don nearly curses at him and tells him to shove off of it).

Smith also misjudged the bad aliens—as in "The Space Trader." On occasion, his frantic warnings proved to be correct ("The Raft," "Wreck of the Robot," and others) but more often than not, he sounded the alarm for no good reason (as in "One of Our Dogs Is Missing).

Smith used the Robot in the early episodes as his companion and protector but by "War of the Robots," he was treating the Robot quite badly, even admitting this at the end and making up for it by giving the Robot a rubdown with oil for two weeks.

By "Ghost in Space" Smith's mind may have completely been changed into a less evil but still silly and selfish man. The takeoff in "The Reluctant Stowaway" may have affected his personality and mind since he was not protected as the Robinsons were from the acceleration (but that doesn't explain future takeoffs).

Smith was also traumatized in "The Magic Mirror" which he refused to believe wasn't his own nightmare world. Smith left Will in the bog in "Ghost in Space," left Will green in "The Girl from the Green Dimension," left Penny alone with Ohan in "All that Glitters," and did various other inane things, screaming at any remote danger or appearance of anything remotely alien.

Smith sometimes was kicked out of camp ("Wish upon a Star," "Attack of the Monster Plants," "The Dream Monster," and "The Mechanical Men"). Due to being ostracized with the silent treatment, he also removed himself in "Mutiny in Space." He removed himself before this at another time in "The Dream Monster" where no one protested his leaving.

There was some question as to whether or not he would leave the planet with them in "Attack of the Monster Plants" but most of this seems to be a ploy to get Smith to behave or a joke from Don—which Judy thinks is cruel. Smith is also left to wonder in "Cave of the Wizards" if the Robinsons would have returned for him if they had been aloft when they spotted him fleeing the alien cave and its influence over him. John seemed to think he would have to remain out in the wilderness thinking about this (another exile?).

Don wanted to leave him on the Xenian space probe and voiced at least three times in "Kidnapped in Space." Smith realized they were always threatening to leave him somewhere in "Time Merchant" ("They were always threatening to leave me somewhere.") In the same episode, Smith's inherent goodness came through and he couldn't allow Judy, Penny, and his dear William to perish, rushing back onto the Jupiter 2 to save their futures, even though it meant his being lost in space again.

Smith threw in with Sesmar in "The Dream Monster," but worked with Don to escape and get the Robinsons' emotions back.

Smith lost his mind when the Jupiter landed on Earth in the year 1947 through a time warp in "Visit to a Hostile Planet," capturing Will and Robot, trying to force the others to stay on Earth in this time to be the masters of it.

Smith may or may not have had medical experience (he seems to know what he is doing in "The Reluctant Stowaway," but Don seems to chide him for not having it in "Kidnapped in Space," but perhaps Don meant mechanical medical history and experience as the patient was robotic).

Smith accidentally causes the ship to crash in "Island in the Sky," "Forbidden World," and "Hunter's Moon" (as Robot says, "A familiar behavior pattern is noted."). He also caused it to go off course some time before "Time Merchant" and in "Wild Adventure" made it lose the auxiliary fuel supply, changed its course toward Earth several times, caused it shake uncontrollably and almost caused a fire. In the same episode, he set it toward the Earth's sun.

He also, in the cliffhanger, places the ship in a deadly radiation belt which endangers it for its ride, also thanks to him to the dangerous "Ghost Planet." Smith was sort of taken over again in "Space Destructors" when he wants to rule the world using an alien machine that makes cyborgs. It seemed to bring out his more evil side. John almost exiled Smith for good after Will was almost turned into a cyborg for all time. Smith's true apology to John made John give him another chance.

Smith's humanity came out in "The Questing Beast" when he regretted every lie he ever told when Will wouldn't believe the truth he told now. Smith also wanted to save Will's youth and innocence in that episode, one of the first times he acted totally unselfishly and he admitted to Will that rushing to grow up isn't all that worth it.

The other time Smith was somewhat evil was when he was being used by the "Space Creature." Smith was turned into a hippie ("The Promised Planet"), a celery stalk ("The Great Vegetable Rebellion"), and a super strong Samson type ("Collision of Planets").

Smith also tried to take over the "A Day at the Zoo" and keep Judy, Don, Will, and Penny as well as the Robot (whom Penny talked into helping them) as specimens in the cages. Don used his laser to threaten Smith in Zoo and "The Flaming Planet," something Smith once almost did to Don in "The Reluctant Stowaway."

Smith abhorred guns as early back as "Welcome Stranger" but took one anyway. By the time the show ended he wouldn't really carry one or even hold one.

Smith tricked Judy into becoming a "Space Beauty" in Farnum's beauty contest unaware it would have dire consequences for her and sold the Robot to "The Space Trader" and the Junkman of "Junkyard in Space" for food both times.

He lied to Maureen in "Return from Outer Space" about the omelet, wanted to see the future in "The Girl from the Green Dimension," conned Will and Penny and Don and almost every member of the Jupiter 2 at one time or another, and made countless errors which endangered everyone—not on purpose most of the time ("Mutiny in Space," "Trip Through the Robot," "The Mechanical Men").

Smith's double Daddy Zack (who was made out of all the inherent goodness of Smith) sang "I've Been Working on the Railroad," a song Smith sang in "The Phantom Family."

Although the most cowardly member of the group, Smith's bravery can be seen in "The Space Primevals" (where he saves Don and bonds with the Major, calling him Don for once), "The Flaming Planet" (where he does save the Robot's sensory tapes), "Time Merchant" and "The Raft" (where he does pull Will away from the dangerous plants).

At first, wildly evil ("The Reluctant Stowaway," "The Derelict," "Island in the Sky," "There Were Giants in the Earth," "The Hungry Sea") he began to mellow by "The Hungry Sea," and although slipping back to being malicious self centered ("Attack of the Monster Plants") and greedy ("My Friend, Mr. Nobody") as well as truly evil minded ("Invaders from the Fifth Dimension"), Smith really didn't think until it was too late (he cared about the fate that befell poor Judy in "A Visit to Hades," worried about what he did to Will in "Ghost in Space," "Space Destructors," and worried about the Robinsons being hypnotized into leaving Penny and Will with monster aliens on "The Promised Planet"), and generally was sorry for the harm he would cause.

Smith lied about changing his ways in "Island in the Sky" (Saint Zachary). After what he thought was "A Visit to Hades" he promised to become St. Pious the third. He also made similar promises in "All that Glitters" ("I'm going to finally be the man that you all want me to be.") and "The Galaxy Gift" (but by this time Maureen didn't count on it). He also wouldn't promise John he would try to change in "Space Destructors" (the worst reversal of his behavior pattern to date—where he wants to rule the universe with cyborgs). Both men knew he couldn't change.

Smith also prayed that he would be a hard worker and a noble man in honor of Will, whom he thought was dead in "Ghost in Space." By "Two Weeks in Space" and "Castles in Space" Smith did seem to be changed somewhat, more an ally than a reluctant castaway, even though he would still dupe anyone anytime to get back to Earth or to get riches.

He did try to save Will from Chavo in "Castles in Space," was unaware of just how dangerous Judy winning the beauty contest would be in "Space Beauty," went with Robot to find Will and the real Professor in "The Anti-Matter Man," helped Will overcome the duplicates in "Target Earth" (although here he told Earth once he left the Jupiter 2 they could blow it up. Will and Robot were still on board), and cared for Don in "Fugitives in Space," not wanting to abandon the hurt Major.

By "Junkyard in Space," he was not the same man, not entirely different (he did sell the Robot to the Junkman). He told Don in "The Space Primevals," he was trying to find a way out of the cave for both of them by enticing a caveman with is grandfather's time piece. This appeared to be true.

Smith saved Don's life in the same episode. Despite haggling both Don and John and harboring some ill thought at them for their being lost—he didn't really blame them ("The Promised Planet") and looked toward them for their expertise (asking John about plans for escape in Kidnapped as well as other episodes; asking Don about hope in the crash landing in "Hunter's Moon"). He appeared to trust in their abilities to lead...most of the time. Other traits include Smith not being very good at math ("Visit to a Hostile Planet").
