As a member of Wisconsin Senator Gaylord Nelson’s legislative staff in 1970, Dennis Brezina assisted in the establishment of Earth Day, an event designed to bring national attention to environmental problems. Much to the surprise of the Senator and his staff, Earth Day was a great success. A graduate of the U.S. Naval Academy in Annapolis, Brezina pursued his interest in the history of science and received an M.A. from Harvard University in 1964. Prior to joining Senator Nelson’s staff, he worked in the Science Research Division of the Legislative Reference Service (the forerunner of the Congressional Research Service) and also the Senate Government Operations Committee’s Subcommittee on Government Research, chaired by Oklahoma Senator Fred Harris.
