Richard Evans Schultes (1915-2001) was probably the greatest explorer of the Amazon, and regarded among anthropologists and seekers alike as the “father of ethnobotany.” Taking what was meant to be a short leave from Harvard in 1941, he surveyed the Amazon basin almost continuously for twelve years, during which time he lived among two dozen different Indian tribes, mapped rivers, secretly sought sources of rubber for the US government during WWII, and collected and classified 30,000 botanical specimens, including 2,000 new medicinal plants. Schultes chronicled his stay there in hundreds of remarkable photographs of the tribes and the land, evocative of the great documentary photographers such as Edward Sheriff Curtis. - See more at: http://www.govindagallery.com/richard-evans-schultes-3/#sthash.23urfCez.dpuf
