Manfred Kochen was born on July 4, 1928 in Vienna, Austria, and came to the USA as a child. He earned a BS (1950) in Physics from MIT and an MA (1951) and PhD (1955) in mathematics from Columbia University, New York.
He was a lecturer at Columbia University, New York City, 1950-1951; Mathematician at Biot & Arnold, New York City, 1950-1953 & Paul Rosenberg Associates, Mount Vernon, NY, 1953-1955.

In 1965 Kochen moved to the University Michigan, Ann Arbor, where he had various roles. He was a professor of information science in the University of Michigan Mental Health Research Institute (MHRI) from 1965, and from 1980, adjunct professor of computers and information systems in the Business School and chairman of the sociotechnological systems area of the Doctor of Philosophy Program in Planning, 1984-1987.

Contributions
Worked on the Neumann computer project at Princeton's Institute for Advanced Study, 1953-55; research mathematician, IBM, 1955-1964; Univ. of Michigan, 1965-1989. Consultant to a wide variety of scientific organizations.
Kochen believed that "authoritative, accurate, easy to access, and easy to understand information could some day be provided to anyone who sought it on almost any topic of interest. He saw collaboration as the key to solving many large problems--in this saw an opportunity for efficient and effective communication by personal networking, avoiding the slow established organizational channels that often separate us" (In Memoriam).
At IBM, he analyzed information needs of scientists and also studied and evaluated information systems. until his death in 1989 in Colorado.
