Abstract :
Richard L. Deininger passed away suddenly on March 30, 1970, at the age of 42. In his combination of engineering and psychological training and in his ability to understand and apply himself to man-machine problems, Dick typified the effective human-factors engineer. His publications made major contributions to the design of computer retrieval systems and pushbutton keyboards. He supervised a group working on telephone design problems both in the laboratory and in the field at Bell Telephone Laboratories. He served as Chairman of the Man-Machine Systems Group of IEEE. He was a fellow of the Division of Engineering Psychologists of the American Psychological Association, American Statistical Association, and the American Association for the Advancement of Science.
