Frederick Rentschler

Rentschler was born on November 8, 1887, in Hamilton, Ohio, to German-Americans George A. Rentschler and Phoebe Schwab, whose family owned the Republic Motor Car Co. that built Republic cars from 1910 until 1916. They were also principals in Hooven-Owens-Rentschler, and his brother Gordon S. Rentschler would become Chairman of National City Bank. The family resided in the Rentschler House, which has since been named a historic site.

He graduated from Princeton University in 1909 and worked in his family's businesses as a molder and machinist. When the U.S. entered World War I in 1917, he joined the United States Army. As a First Lieutenant and later Captain, he was assigned to inspect Hispano-Suiza aircraft engines manufactured under French license at the Wright-Martin plant in New Brunswick, New Jersey. The armistice of November 11, 1918, ended the contract and caused the reorganization of Wright-Martin.

Rentschler approached the Pratt & Whitney Machine Tool Company of Hartford, Connecticut, with his idea. On July 23, 1925, they agreed to fund its development, creating the Pratt & Whitney Aircraft Company in which Rentschler and Mead had a controlling position.

Pratt & Whitney Aircraft's first engine, completed on Christmas Eve 1925, was named the Wasp by Faye Belden Rentschler, whom Frederick had married July 25, 1921. The 425 horsepower (317 kW) Wasp easily passed its official qualification test in March 1926 and the Navy ordered 200 engines. The speed, climb performance, and reliability that the engine offered revolutionized American aviation. Over the next twenty years, from the original Wasp design the Pratt & Whitney Wasp series developed, approaching ten times the power of the 1925 engine.

In 1929, Rentschler ended his association with Pratt & Whitney Machine Tool Company, but was allowed to keep the name Pratt & Whitney Aircraft Company. Rentschler, Vought and William Boeing of The Boeing Company formed the United Aircraft and Transport Corporation. United Aircraft completed the first coast-to-coast passenger network in March of that year.

In 1934, UATC was broken up, and its manufacturing interests east of the Mississippi River became United Aircraft Corporation, headquartered in Hartford with Rentschler as president.

Rentschler turned to developing jet engines after World War II. Pratt & Whitney produced the J57 jet engine in 1953. The engine was used to power the first B-52 Stratofortress in 1954.

Rentschler remained as president of United Aircraft until his death on April 25, 1956, in Boca Raton, Florida. He is buried at Fairview Cemetery in West Hartford.
