Douglas L. Coleman

Douglas L. Coleman was a scientist and professor emeritus at the Jackson Laboratory, in Bar Harbor, Maine. His work predicted that there exists a hormone that can cause mice to feel full, and that a mutation in the gene encoding this hormone can lead to obesity. The gene and corresponding hormone were discovered about 20 years later by Jeffrey M. Friedman, Rudolph Leibel, and their research teams at Rockefeller University, which Friedman named leptin.
