IRVING JOHN GOOD, 92

Helped break Nazi Enigma code

Irving John "Jack" Good, a retired Virginia Tech statistician who helped break the Nazi Enigma code for his native England during World War II, died Sunday in Radford, Va., the university said. He had been a professor of statistics at Tech since 1967.

A citizen of Great Britain, Dr. 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.

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

CONSTANTINE PAPADAKIS, 63

Drexel University president

Constantine Papadakis, the Drexel University president who is credited with raising the endowment, enrollment and profile of the one-time commuter school, died of complications from lung cancer Sunday evening in Philadelphia, three days after he officially stepped down to take medical leave. A statement from Drexel issued Monday said his lung cancer was in remission but that Papadakis died of pulmonary complications.

Dr. Papadakis became Drexel's president in 1995 and began shoring up the school's finances, eventually overseeing construction of numerous campus buildings. Under his leadership, the university acquired schools of medicine, nursing and public health.
