Dr Irving John "Jack" Good
Birth: Dec. 9, 1916
London, England
Death: Apr. 5, 2009
Radford City
Virginia, USA

British Mathematician, he was the founder of the "Bayesian inference", the basis of the modern science of statistics. During World War II, he helped break the German submarine communications codes, and later assisted in the creation of the modern science of computers. Born Isidore Jacob Gudak (his father was a well-known Yiddish writer), he was raised in London. Slow to learn to read, he displayed high mathematical intelligence from around age nine; winning a scholarship to Cambridge, he graduated in 1938, won 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"; much of the work remains classified, 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 followed them to the University of Manchester in 1947, 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 moved to America in 1967, 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. (bio by: Bob Hufford)
