Dick Houston has spent most of his adult life in Africa as a safari leader, conservationist, writer, and teacher. Born in Ohio, he taught English at schools in the United States, Venezuela, Kenya, and Zambia. As a safari leader, he ran journeys across the Sahara Desert, through the rain forests of central Africa, and in the bush country of eastern and southern Africa. He has written on African topics for Smithsonian, the New York Times, the Los Angeles Times, and Reader's Digest. His commitment to saving Africa's vanishing wildlife led him to help found Elefence International, a nonprofit group dedicated to elephant conservation in Zambia.
