Data a humanoid
android so sophisticated that he was regarded as a sentient life-form with
full civil rights. ("Encounter at Farpoint, Part II" [TNG]). Creation. Data
was built around 2336 by the reclusive scientist Noonien Soong and his wife,
Juliana Soong at the Omicron Theta colony. Data was actually the fifth positronic
android constructed by Soong; the first three were unsuccessful. ("Inheritance"
[TNG]). The fourth, the first to become functional, was known as Lore.
("Datalore" [TNG]). After Lore's behavior forced Soong to disassemble him,
Soong pursued the idea of manufacturing an android free of emotions. Soong
hoped this new android would not exhibit the dangerous cruelty shown by Lore.
Juliana had wanted Data to have a female form, but Noonien, as before, created
Data in his own image. Following his activation, Data was much like a baby,
though he was made in the form of a full grown adult. Data had difficulty
learning basic social skills, and "social niceties" had to be built into
his programming. In addition, a creative capacity was also programmed into
Data by Mrs. Soong, who reasoned that without emotions, the android would
need another way to express himself. After this initial period, Data was
thought unsuccessful and was deactivated. ("Inheritance" [TNG]). He was
programmed with the logs and journals of the Omicron Theta colonists in an
effort to help Data function better in human society. ("Datalore" [TNG],
"Silicon Avatar" [TNG]). Unfortunately, before Data could be reactivated,
the Crystalline Entity attacked the colony, and Soong and his wife Juliana,
were forced to abandon their work. Fearing that when reactivated, Data might
behave as Lore did, Juliana made Dr. Soong leave Data at the colony site.
("Inheritance" [TNG]). Data remained in a dormant condition underground,
where he was discovered in 2338 by the crew of the Starship Tripoli. Data
subsequently joined the Starfleet and eventually became operations manager
aboard the Enterprise - D. ("Datalore" [TNG]). Form and function. Data was based on a sophisticated positronic brain developed by Soong, from concepts first postulated in the 20th century by Dr. Isaac Asimov. ("Datalo re" [TNG]). Data's body closely mimicked humanoid form, and contained approximately 24.6 kilograms of tripolymer composites, 11.8 kilograms of molybdenum-cobalt alloys, and 1.3 kilograms of bioplast sheeting. ("The Most Toys" [TNG]). His upper spinal support was polyalloy, while his skull was composed of cortenide and duranium. ("The Chase" [TNG]). Soong went to extraordinary lengths to create a naturalistic human appearance in Data. He gave Data a functional respiration system, although its purpose was primarily for thermal regulation. (Data was in fact capable of functioning for extended periods in a vacuum. ["Brothers' (TNG)].) He gave Data a pulse in his circulatory system that distributed biochemical lubricants and regulated microhydraulic power throughout Data's body. Data's hair was even capable of growth at a controllable rate. ("Birthright, Part I" [TNG]). Data did not require food; he occasionally ingested a semi-organic nutrient suspension in a silicon-based liquid medium. ("Deja Q" [TNG]). Although Data's systems were primarily mechanical, cybernetic, and positronic, sufficient biological components were present to allow him to become infected by the Psi 2000 virus in 2364. While under the influence of the inhibition-stripping effects of that virus, Data apparently became intimate with Enterprise -D security chief Tasha Yar. ("The Naked Now" [TNG]). Data's basic programming included a strong inhibition against harming living beings, but he nevertheless had the ability to use deadly force to protect others. ("The Most Toys" [TNG]).
Data in Starfleet. Prior to his assignment to the Enterprise-D, Data served aboard the U.S.S. Trieste. During this tour-of-duty, the Trieste once fell through a wormhole. ("Cl ues" [TNG]). Aboard the Enterprise -D, Data served as operations manager, and was in charge of coordinating the many departments aboard the ship. ("Encounter at Farpoint" [TNG]). In 2366, Commander Data was seriously injured trying to save Q from an attack by gaseous creatures called the Calamarain. In gratitude, Q gave Data the gift of allowing Data to experience human laughter for a brief time. ("Deja Q" [TNG]). Data served as father of the bride for the wedding of Miles O'Brien and Keiko Ishikawa in 2367, and found it necessary to learn to dance to fulfill this ceremonial function. ("Data's Day" [TNG]). Data's first opportunity to command a starship came during the Federation blockade during the Klingon civil war of 2368. Data was assigned temporary command of the Starship Sutherland in Picard's armada. As an android, Data encountered a small amount of prejudice among his human crew, but was nevertheless able to lead effectively. ("Redemption, Part II"[TNG]). In late 2368, Data traveled back in time to old San Francisco when bizarre evidence was found suggesting that he had died some 500 years ago. The evidence was Data's severed head, unearthed from beneath the city of San Francisco, where it had been buried for five centuries. ("Time's Arrow, Part I" [TNG]). Back in the year 1893, Data uncovered a plot by aliens from the planet Devidia II who were using the cholera plague of the time to conceal their murder of humans. While attempting to stop the Devidians, Data's head was severed, and his body was sent forward in time, back to 2368. Aboard the Enterprise -D, Geordi La Forge was successful in reattaching Data's head and body. ("Time's Arrow, Part II" [TNG]). Data and Lore. Upon returning to the Omicron Theta colony site in 2364, Data participated in the discovery and activation of his android brother, Lore. Physically identical to Data, Lore had radically different personality programming, and attempted to commandeer the Enterprise-D before he was beamed into space. ("Datalore" [TNG]). Although Soong was believed to have died at Omicron Theta, he was discovered to have escaped the colony when, in 2367, he remotely gained control of Data, commanding his creation to visit him in his new secret laboratory. There, Soong attempted to install a new chip in Data's positronic brain that would have given Data the ability to experience human emotions. Unfortunately, Lore also responded to Soong's call, and stole the emotion chip from Soong's lab. Dr. Soong died shortly thereafter. ("Brothers" [TNG]). Data began to experience emotions in 2369 when Lore secretly bombarded Data with signals that triggered negative emotions in his positronic brain. Lore used these negative emotions to guide Data into joining him and the Borg against the Federation. When Data realized that Lore was manipulating him and harming the Borg, he was forced to deactivate Lore. Data kept Soong's emotion chip, but was reluctant to install it for fear of causing further harm to his friends. ("Descent, Parts I and II" [TNG]). Efforts to understand humanity. Data's attempts to understand human nature once included an effort to learn about the concept of humor, which he studied with the assistance of Guinan and a holodeck-created comedian. ("The Outrageous Okona" [TNG]). Data even tried a beard once, to the considerable amusement of his shipmates. ("The Schizoid Man" [TNG]). Aboard the Enterpris e-D, Data shared his living quarters with a cat that he named Spot. Data tried to provide for Spot's well-being, but found it difficult to predict the cat's preferences in food. ("Data's Day" [TNG]). One of Data's more challenging efforts to experience humanity was his attempt to pursue a romantic relationship with Enterprise -D security officer Jenna D'Sora in late 2367. Although D'Sora was attracted to Data, he was unable to return the affection, at least in a manner that she wanted. ("In Theory" [TNG]). Data began to experience dreams in 2369 as a result of an accidental plasma shock received during an experiment. It was later learned that the shock had triggered a program designed for this purpose by Soong, who had hoped the program would be activated when Data reached a certain level of development. Data's initial dreams were of Soong as a blacksmith, incongruously forging the wings of a bird, which Data believed represented himself. ("Birthright, Part I" [TNG]). Those dreams turned to nightmares while under the influence of interphasic organisms in 2370. ("Phantasms" [TNG]). Later that year, following the Enterprise -D's discovery of the D'Arsay archive, Data's own personality became completely submerged by a series of personas, enacting the mythology of a long-dead civilization. Following the experience, Captain Picard commented that even if Data never become human, he had transcended the human condition by becoming an entire civilization. ("Masks" [TNG]). One of Data's most noteworthy efforts in his quest for humanity was his construction of an android daughter in 2366. Data employed a new submicron matrix transfer technology to allow his own neural pathways to be duplicated in another positronic brain, which he used as the basis for his child. His daughter, whom he named Lal (Hi ndi for "beloved"), developed at a remarkable rate and showed evidence of growth potential beyond that of her father, even experiencing emotions. Lal died after having lived little more than two weeks, when she experienced a serious failure in her positronic brain. ("The Offspring" [TNG]). In 2371, Data finally decided to install the emotio n chip that Dr. Soong had created for him. Although Data had initial difficulty coping with the resulting flood of emotions, a problem made worse when the chip became fused into his neural net, the chip represented a significant step in his quest to become more human. (Star Trek: Generations). Android rights. The question of Data's sentience, and more specifically whether Data was entitled to civil rights under the Constitution of the United Federation of Planets, was addressed in a number of important legal decisions. The first, in 2341, was rendered by a Starfleet Academy entrance committee that permitted Data to enter the Academy and serve as a member of Starfleet. Several years later, the question was more definitively addressed when Judge Advocate General Phillipa Louvois ruled that Data was indeed a sentient being and therefore entitled to civil rights, including the right to resign from Starfleet if he so chose. As of stardate 42527, Data had been decorated by Starfleet Command for gallantry and had received the Medal of Honor with clusters, the Legion of Honor, and the Star Cross. ("The Measure of a Man" [TNG]).
