“”Here's this person, who is being murdered for who he is, after being one of the heroes for liberating people who were being murdered for being who they were.
Alan Turing was a British mathematical academic who was responsible for running the Bletchley Park SIGINT operation during World War II. He was also gay and was the victim of government persecution due to the UK's then-policy prohibiting homosexuality.
The fact that someone who may have been one of the top ten most important people responsible for winning the war was treated like scum by a government who should have been making him comfortable for life may or may not have had something to do with later liberalizations of laws in the UK regarding homosexuality. In any event, during the 1950s Turing chose the Snow White route, apparently spiking an apple with cyanide (the apple was never tested to be sure) and therefore never living to see the eventual revealing of his pivotal role in the Allied war effort, not to mention his lionization as the alpha hacker of all alpha hackers in the computer field.
 Church-Turing thesis
Turing is regarded as one of the fathers of computer science for his co-development, with Alonzo Church, of the Church-Turing thesis, which hypothesized that any problem that is "effectively computable" (solvable by mechanical means) can be solved using a certain sort of formally specified machine, which is now called a Turing machine.
He also devised a "universal Turing machine" that could "compute any function that any Turing machine can compute," which was a "blueprint" for the later general-purpose computers. According to the Stanford Encyclopedia of Philosophy, many philosophers of science, being unacquainted with the finer points of the theory, have grossly misinterpreted the thesis, falsely stating that it proves Turing machines to be capable of computing all that is computable, or that any possible computer architecture is no more powerful than the Turing machine.
 Turing Test
The Turing Test is a well known method for ascertaining computer "intelligence." It consists of a person (judge) communicating with two subjects, one of which is human and the other a computer. If the judge is unable to distinguish between human and machine then the computer is said to display intelligence. The communication is nowadays via typed words on a screen in order to remove other sensory clues. Turing originally conceived the idea from a variant of a sex detection parlour game and envisaged teletype as the communication medium. The Chinese room thought experiment attempts to refute the Turing test's standard for judging artificial intelligence.
 The imitation game
The original formulation of the test was known as "The Imitation Game" where person A attempted to impersonate person B - it was then up to the interviewer (Person C, if you will) to decide who was telling the truth and who was lying. Possibly due to Turing's interest in the nature of gender, he usually described A and B as a man and woman couple - with one pretending to be the other gender. The interviewer could ask questions and A and B, who were isolated from the interviewer so that even their voices wouldn't be heard, would then answer. The basis of the imitation game with regards to the development of the Turing Test was the question of what would happen when one of these individuals, A or B, was replaced by a machine (a computer, in our more modern views on how the test can be carried out). Unfortunately, this was as bit too much of a gender-bender for people's squeamish sensibilities, and almost every subsequent version of the test conducted left this part out, leaving it as just an interviewer and a simulated interviewee.
 Extra points
Extra points can be earned by either computer or human if they are able to convince the judge that he (the judge) is a computer.
Turing was convicted of having a sexual relationship with another man in 1952 and was given a choice between jail time and chemical castration through the hormone estrogen, and chose the latter. His security clearance was revoked, leaving him unable to continue his work in cryptanalysis. He died two years later of cyanide poisoning, which was ruled to have been a suicide after an investigation, though his mother thought the death might have been accidental.
In 2009, the British government apologized for thus driving one of the most brilliant scientists of the 20th century to his death.
 Overturning of conviction
Criticisms against the legistlation ranged from poor education of law ("Oh, you're rewriting history!"), ad hominem ("This is why I can't take left-wing arguments seriously!") to outright homophobia ("There were rumours that Turing was a child molester!"). The three likely overlap.
 Turing and Apple Computer
While Apple Computer's bitten-apple logo is generally accepted to have been a reference to the story of Isaac Newton's apple, there is a curious urban legend to the effect that it is instead an homage to Alan Turing. This hypothesis is largely discounted, although still very prevalent.
