Born in Berkeley, California, in 1912, David Brower has been fighting conservation battles since 1938. Mr. Brower joined the Sierra Club in 1933 and was its first executive director from 1952 to 1969. In one of his more famous campaigns, he prevented the Grand Canyon from being dammed. Brower saw the club’s membership grow from two thousand to seventy-seven thousand before leaving on request in 1969, after which he founded Friends of the Earth, the League of Conservation Voters, and Earth Island Institute. As a climber and mountaineer, Brower made seventy first ascents. He has been nominated for the Nobel Peace Prize three times. He remained politically active and led his supporters to take on important environmental issues up until his death in November of 2000.
