The story
In 1966, U.S. Surgeon General William H. Stewart helped to create a Division of Environmental Health Sciences within the NIH. Three years later, the division became its own institute, the National Institute of Environmental Health Sciences. Past directors include Paul Kotin, David Rall, Kenneth Olden, David A. Schwartz, and Linda Birnbaum.
