Cyanide poisoning of Alan Turing

Alan Mathison Turing, (23 June 1912 – 7 June 1954) was an English mathematician, logician and cryptographer. Turing is often considered to be the father of modern computer science.

On 8 June 1954, Alan Mathison Turing’s cleaner found him dead; the previous day, he had died of cyanide poisoning, apparently from a cyanide-laced apple he left half-eaten beside his bed. The apple itself was never tested for contamination with cyanide, but a post-mortem established that the cause of death was cyanide poisoning. Most believe that his death was intentional, and the death was ruled a suicide. His mother, however, strenuously argued that the ingestion was accidental due to his careless storage of laboratory chemicals.
