I. J. Good

Who was I. J. Good?

Irving John Good was a British mathematician who worked as a cryptologist at Bletchley Park with Alan Turing. After World War II, Good continued to work with Turing on the design of computers and Bayesian statistics at the University of Manchester. Good moved to the United States where he was professor at Virginia Tech.

He was born Isadore Jacob Gudak to a Polish-Jewish family in London. He later anglicized his name to Irving John Good and signed his publications "I. J. Good."

An originator of the concept now known as "technological singularity," Good served as consultant on supercomputers to Stanley Kubrick, director of the 1968 film 2001: A Space Odyssey.
