David Blanton first visited the Serengeti in 1975 while working in Kenya as a writer and photographer. During that time, he became involved in tourism training and developed a social studies curriculum at Utalii College, Kenya’s tourism and hotel training facility. The course focused on social and cultural aspects of tourism for students entering travel careers.
After returning to the United States, Blanton founded a Voyagers International, a travel company which operated for twenty years and catered to U.S. universities, museums, and zoological societies. During this time, he founded the International Galapagos Tour Operators Association (IGTOA), a nonprofit organization for travel companies that has raised millions of dollars for Galapagos conservation.
While running IGTOA, he was alerted to the threat of a highway that was being proposed across the Serengeti. In response, he co-founded Serengeti Watch, a project of the US Earth Island Institute, located in Berkeley, California.
Serengeti Watch sponsored a court case in the East African Court of Justice and helped stop the highway. He has been operating Serengeti Watch since then, working with a partner in Tanzania, the Serengeti Preservation Foundation. In addition, he founded Friends of Serengeti, an association for the travel industry patterned after IGTOA, that funds community conservation.
