Dr Irving John "Jack" Good
Birth: Dec. 9, 1916

World War II Figure. A mathematician who formulated the "Bayesian inference", the basis of the modern science of statistics, he is remembered for his part in breaking Enigma, the supposedly-unbreakable German code machine. Born Isadore Jacob Gudak to a well-known Yiddish writer father, he was raised in London; slow to learn to read, he displayed high mathematical intelligence from around age nine, won a scholarship to Jesus College, Cambridge, from whence he graduated in 1938, earned a Smith Prize in 1940, and obtained his Ph.D. in 1941. In 1941, he was recruited to work at the Government Code and Cipher School (GCCS) at Bletchley Park, Buckinghamshire. For many years, GCCS, Bletchley Park, and the people working there, did not even officially "exist", and much of the work will probably remain classified forever, though Bletchley Park is now a public museum. Working in Hut 8 as Alan Turing's deputy, Dr. Good developed early computers called "Bombes" to perform the statistical analysis necessary to decipher the Nazi Enigma code machines. He transferred to Newmanry, Max Newman's group, in 1943, where early computers such as "Heath Robinson", and "Colossus" were developed. When GCCS became Government Communications Headquarters (GCHQ) after the war, Dr. Good continued there with Turing and Newman, then in 1947 followed them to the University of Manchester, where the first truly "modern" computer, the Manchester Mark I, was invented. His first book, "Probability and the Weighing of Evidence", was published in 1950, though GCHQ was nowhere mentioned. He left GCHQ for the Admiralty Research Laboratory in 1959, then in 1967 moved to America where he was a professor at Virginia Tech until assuming emeritus status in 1994. Shortly after his arrival he was Stanley Kubrick's scientific advisor for "2001: A Space Odyssey". Dr. Good's last major book, "Good Thinking: the Foundations of Probability and its Applications", was published in 1983. He lived out his days in Blacksburg, died of the effects of advanced age, and in 2014's cinematic feature "The Imitation Game" was portrayed by James Northcote. (bio by: Bob Hufford)
