By all accounts, Dean S. Edmonds Jr. was quite a man. Briefly summarized, he earned his Ph.D. at MIT in 1958 for work on the cesium atomic clock, following his U.S. Army service from 1943 to 1947.
He was a professor of physics at Boston University for 30 years until his retirement in 1991. An avid pilot, he earned his commercial multi-engine and instrument rating and joined a group learning to fly a B-17 when he was 91 years old.
