Edgar Wayburn, American physician and environmentalist (d. 2010)
Edgar Arthur Wayburn (September 17, 1906 – March 5, 2010) was an American environmentalist who was elected president of the Sierra Club five times in the 1960s. He has been described as one of the least-known and yet most successful defenders of America's natural heritage. He is considered instrumental to achievements such as the creation of the Golden Gate National Recreation Area, the creation and later expansion of Redwood National Park and Point Reyes National Seashore, and the expansion of Mount Tamalpais State Park.
