John P. Schaefer, Honorary Chairman of the Board

John Paul Schaefer was dean of the University of Arizona College of Liberal Arts when he became the 15th president of the University of Arizona in 1971. Only 36 years old when he assumed the office, he was the second-youngest UA president. Born on Sept. 17, 1934, in New York City, he received a bachelor’s degree from the Polytechnic Institute of Brooklyn in 1955, and a doctorate from the University of Illinois in 1958. Following his postdoctoral studies, he taught chemistry at the University of California at Berkeley, before coming to the UA as a chemistry professor in 1960. He also served as head of the chemistry department from 1968 to 1970.

Schaefer is credited by many with setting the University of Arizona on the path that led to its current status as a top research university. He approved the university’s participation in the Multiple Mirror Telescope project, which revolutionized thinking about optical telescope design. During his tenure, he also broke ground for and dedicated the new UA Main Library.

An avid and highly skilled photographer, Schaefer developed a friendship with photographer Ansel Adams, which led to the creation of the Center for Creative Photography in 1975. The center was created after Schaefer asked Adams to entrust the UA with his archives.
