January 23, 1941 groundbreaking ceremony at the NACA Aircraft Engine Research Laboratory: left to right (does not include two individuals obscured from view behind Maj. Brett and Dr. Lewis): • William R. Hopkins – Cleveland City Manager from 1924-1930, was personally responsible for planning and acquiring the land for the Cleveland Airport. The airport’s huge capacity for handling aircraft was one factor in selecting Cleveland for the site of the research center. The Cleveland Airport was renamed Cleveland Hopkins airport in his honor in 1951.
 • Major John Berry – Cleveland Airport Manager • Edward R. Sharp – GRC’s first director, serving from 1942 to his retirement in 1961. He came to Cleveland in 1941 as the construction manager for the new facility.
 • Frederick C. Crawford – President of Thompson Products, which became the Thompson-Ramo-Woolridge Corporation (TRW) in 1958. Crawford was, at the time, also president of the Cleveland Chamber of Commerce. He began in 1939 to campaign for Cleveland as the location for the new NACA facility.
 • Major George H. Brett – A Cleveland native, Brett served in WWI and was commanding officer at Wright Field in Dayton, Ohio before becoming chief of the Army Air Corps.
 • Dr. Edward P. Warner – Acting chairman of the NACA.
 • Captain Sydney M. Kraus – Officer in charge of Navy procurement
 • Edward Blythin – Mayor of Cleveland
 • Dr. George Lewis – Director of Aeronautical Research for the NACA from 1924-1947, Lewis devoted his life to building a scientific basis for aeronautical engineering. The Cleveland laboratory was renamed the Lewis Flight Propulsion Laboratory in his honor in 1948. A description of the event, based on newspaper accounts and later NASA publications is as follows: On January 23, 1941, a brief groundbreaking ceremony at the site marked the start of construction. Dr. George W. Lewis, director of research for the NACA, loosened the soil with a

Addison Rothrock, the National Advisory Committee for Aeronautics’s (NACA) Assistant Director of Research, speaks at the groundbreaking ceremony for the Lewis Flight Propulsion Laboratory’s new test reactor at Plum Brook Station. This dedication event was held almost exactly one year after the NACA announced that it would build its $4.5 million nuclear reactor on 500 acres of the army’s 9000-acre Plum Brook Ordnance Works. The site was located in Sandusky, Ohio, approximately 60 miles west of the NACA Lewis laboratory in Cleveland. Lewis Director Raymond Sharp is seated to the left of Rothrock, Congressman Albert Baumhart and NACA Secretary John Victory are to the right. Many government and local officials were on hand for the press conference and ensuing luncheon. In the wake of World War II the military, the Atomic Energy Commission, and the NACA became interested in the use of atomic energy for propulsion and power. A Nuclear Division was established at NACA Lewis in the early 1950s. The division’s request for a 60-megawatt research reactor was approved in 1955. The semi-remote Plum Brook location was selected over 17 other possible sites. Construction of the Plum Brook Reactor Facility lasted five years. By the time of its first trial runs in 1961 the aircraft nuclear propulsion program had been cancelled. The space age had arrived, however, and the reactor would be used to study materials for a nuclear powered rocket.

Local politicians and National Advisory Committee for Aeronautics (NACA) officials were on hand for the January 23, 1941 groundbreaking for the NACA’s Aircraft Engine Research Laboratory (AERL). The NACA was established in 1915 to coordinate the nation’s aeronautical research. The committee opened a research laboratory at Langley Field in 1920. By the late 1930s, however, European nations, Germany in particular, were building faster and higher flying aircraft. The NACA decided to expand with a new Ames Aeronautical Laboratory dedicated to high-speed flight and the AERL to handle engine-related research. The NACA examined a number of Midwest locations for its new engine lab before deciding on Cleveland. At the time, Cleveland possessed the nation’s most advanced airport, several key aircraft manufacturing companies, and was home to the National Air Races. Local officials were also able to broker a deal with the power company to discount its electricity rates if the large wind tunnels were operated overnight. The decision was made in October 1940, and the groundbreaking alongside the airport took place on January 23, 1941.
