WILLIAM E. THORNTON
Signature of the astronaut and groundbreaking medical researcher
Signature: "Wm. Thornton", 6½x3¾. Conquest of Space ink stamp on left margin. William Edgar Thornton (b. 1929) is a former American astronaut. He completed training as a United States Air Force flight surgeon in 1964 before NASA selected him as a science astronaut in 1967. He's been mission specialist on two space shuttle missions: STS-8 in 1983 and STS-51B in 1985. But his greatest contributions may come from his work on the ground. He studied muscle loss and mass in space flight, an important discovery in the development of long-duration space flights, and has since developed equipment and procedures to combat this. He retired from NASA in 1994 and is currently a Clinical Assistant Professor in the Department of Medicine at the University of Texas Medical Branch in Galveston, Texas and an adjunct professor at the University of Houston-Clear Lake. Fine condition.
