Edward Abbey (1927-1989) was an American writer and environmentalist best known for his works about the American Southwest. Abbey published several works that were influential on the environmental movement of the 1970s, notably Desert Solitaire (McGraw-Hill, 1968) and The Monkey Wrench Gang (Lippincott Williams & Wilkins, 1975), which inspired a wave of environmentalist protests involving industrial sabotage. In the final years of his life, Abbey worked on several writing projects, including The Fool's Progress (Henry Holt and Company, 1988), a picaresque novel that was Abbey's last published work before his death in 1989. Several of his final works were published posthumously.
Katie Lee (1919- ) is an American folk singer and environmentalist. Born in Arizona, Lee studied fine arts at the University of Arizona before becoming a folk singer and songwriter. Much of her music deals with the musical traditions and landscape of the American West, notably her album Folk Songs of the Colorado River (Folkway Records, 1964). Lee was an advocate for several environmentalist causes, including the protection of Glen Canyon. Lee has published three books, including Ten Thousand Goddam Cattle (University of New Mexico Press, 1976) and Sandstone Seduction (Johnson Books, 2004).
