Today in 1954, Alan Turing died from cyanide poisoning. An inquest determined that his death was suicide; his mother and some others believed his death was accidental. Turing is widely considered to be the father of computer science and artificial intelligence. Check out the CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) exhibit at the Jerusalem Museum of Science in honor of Alan Turing and the talk by the curator of the exhibition, Nathan Zeldes.
