Alan Turing died by suicide on 7 June 1954. Turing was convicted of gross indecency in 1952 and given a choice between imprisonment and probation. His probation would be conditional on his agreement to undergo hormonal physical changes designed to reduce his libido. Turing's conviction led to the removal of his security clearance and barred him from continuing with his consultancy for GCHQ. He was denied entry into the United States after his conviction.
