Dr. Silverstein began his scientific career with the National
Advisory Committee for Aeronautics in 1929 at the Langley
Research Center. There he helped design and later was placed in
charge of the Full-Scale Wind Tunnel. In this facility he
directed important aerodynamic research which led to increased
high-speed performance of most of the combat aircraft of World
War II. In 1943 he was transferred to the Lewis Laboratory at
Cleveland. As Chief of the Wind Tunnel and Flight Division, he
directed research in propulsion aerodynamics in the Altitude
Wind Tunnel. These investigations led to significant
improvements in both reciprocation and early turbojet aircraft
engines. He also pioneered research on large scale ramjets
engines. Following World War II, Dr. Silverstein was responsible
for the conception, design and construction of our nation's
first supersonic propulsion wind tunnels. The investigations in
these facilities greatly contributed to the development of our
present day supersonic aircraft. Dr. Silver
