Alan Turing was called many things during his time; mathematician, cryptanalyst and computer science pioneer are just some of the titles he has on his shoulders. He contributed to many fields, but is acclaimed for his work in mathematics, the computing community, and for his efforts in cryptography during World War II. Alan Turing was born on June 23, 1912 to a wealthy, middle-class family. His parents, Julius and Sara Turing, had met in India and had previously had another child with whom Turing spent his childhood. Alan's rise to fame began after his admission to King's College in 1931. By 1936 he had not only graduated with a degree in mathematics, but had also been awarded a Fellowship, or member of a group of colleagues working together in the pursuit of knowledge. , and won the Smith Prize for his work on probability theory (Huertas). With the introduction of Gödel's paper in 1931, a whole new world of mathematics opened up for Turing. In 1935 Turing realized that the question of decidability, or Entscheidungsproblem, which asks whether there is a method or process by which one can decide whether a given mathematical statement is provable, was still open. He gave a negative answer by defining a definite method or algorithm in today's terms. He analyzed the characteristics of a methodical process and how to carry it out and expressed his findings in terms of a theoretical machine that would be able to perform operations on symbols on a paper tape. This correspondence between operations, the human mind and a machine designed to embody a certain physical form was Turing's (Huertas) contribution. Shortly after his appointment and research at Kin...... half of the document...... waiting though when he was arrested in 1952 over a sex scandal involving a young man from Manchester. He was given the option of confinement or chemical castration, from which he chose castration by injection of estrogen. All his previous contributions to the world of cryptography seemed futile as his access to secret cryptography projects was revoked due to fears that the KGB, or the Russian Committee for State Security, might trick gay males into leaking sensitive materials . Only two years passed when Alan Turing died after consuming an apple dipped in cyanide. Although it is generally accepted that his death was a suicide, there were many people at the time who thought that assassination should not be ruled out. This has led to the emergence of several conspiracy theories that Turing was poisoned to prevent the leak of national secrets (Hodges).
