Dr. Lee Alvin DuBridge ’22, an internationally known physicist who helped to develop radar during World War II, was president of California Institute of Technology. He led CalTech from 1946 to 1969, when President Richard Nixon appointed him White House science adviser. DuBridge retired from that position after 18 months but remained a member of the President’s Science Advisory Committee.
President Harry S. Truman had first named him to that committee in 1951, when it was new. The following year, President Dwight D. Eisenhower made him chairman, a position he held until 1958.
DuBridge was known as a gentle, unflappable man who moved CalTech from a waroriented program of secret military projects after World War II back into fundamental scientific interests. He also managed an extraordinary expansion of CalTech.
