After 33 years on the Princeton faculty, the Hazen family moved to Washington, D.C., then to Daytona Beach, Fla., and then returned to Maryland.
At Princeton David graduated summa cum laudein aeronautical engineering and was elected to Phi Beta Kappa. He earned a master’s degree in 1949 and immediately joined the faculty as an instructor, becoming a full professor in 1963. Concurrently he served as a department chairman and later as an associate dean of the faculty. He retired in 1982.
He served as executive director of engineering and technology for the National Research Council. He was a consultant for more than 40 years to the Navy and Marine Corps. Internationally he organized and advised on development of academic and governmental aeronautical engineering programs and organizations, first for a year in Kanpur, India, and later in Jordan, Turkey, and Saudi Arabia. He then led organizational design and academic program development at Embry-Riddle Aeronautical University of Daytona Beach, Fla., while earning a doctoral degree there! (Read Dave’s more detailed account of all this in the Class of 1948 50th-reunion book.)
David is survived by his wife of 70 years, Mary Ann; son George ’73; daughter Anne Brendel; five grandchildren; and four great-grandchildren. Their son Thomas died in 2014.
