Harry Raymond Eastlack, Jr. (1933 1973) died from fibrodysplasia ossificans progressiva (FOP), a rare and poorly understood disease in which the bone repair mechanism runs out of control, turning other tissue like muscles and tendons into bone. Eastlack permitted his skeleton to be preserved for scientific research, and it is today on display at the Mtter Museum. His skeleton is one of the few existing in the world and a valuable asset to the study of the disease.
