RADFORD, Virginia - Irving John "Jack" Good, a retired Virginia Tech statistician who helped break the Nazi Enigma code for his native England during World War II, has died. He was 92.

Good died Sunday, the university said. He had been a professor of statistics at Tech since 1967.

A citizen of the United Kingdom, Good had worked for British military intelligence on a code-breaking team at Bletchley Park, England. He and other scientists developed an early version of the computer to break one of the German encryption systems.

He later went on to pioneer developments in an approach to statistics known as Bayesian inference, in which new information is used to update the probabilities of future outcomes.

Good also advised Stanley Kubrick on the science related to the film "2001: A Space Odyssey."
