Frederick Rentschler

Frederick Brant Rentschler was an American aviation engineer and entrepreneur born in 1887 in Hamilton, Ohio. Rentschler served as chief engineer and president of Wright Aeronautical before departing to pursue his own engine designs. In 1925, he negotiated an arrangement with the Pratt & Whitney Machine Tool Company to use its Hartford, Connecticut factory and the Pratt & Whitney name to develop his revolutionary Wasp radial aircraft engine. Rentschler's engineering vision and entrepreneurial drive established Pratt & Whitney Aircraft as a dominant force in American aviation.

Frederick Rentschler founded Pratt & Whitney Aircraft Company in 1925 after leaving Wright Aeronautical, where he had developed a reputation as one of America's most gifted aircraft engine designers. Recognizing that the U.S. Military needed a new generation of high-powered, lightweight aircraft engines, Rentschler designed the Wasp engine — a 400-horsepower air-cooled radial that represented a quantum leap in power-to-weight ratio over existing designs. The Wasp was immediately adopted by the U.S. Navy, and Rentschler quickly followed it with the Hornet engine, which produced 525 horsepower. By 1929, Pratt & Whitney engines powered Charles Lindbergh's Lockheed Sirius, the U.S. Navy's primary fighter aircraft, and the world's fastest aircraft. Rentschler's commercial instincts were as sharp as his engineering talent — he recognized early that military contracts alone would not sustain the business and worked aggressively to develop relationships with commercial aviation pioneers. His foundational work established the engineering culture and customer relationships that made Pratt & Whitney the dominant U.S. Aircraft engine manufacturer for the first five decades of commercial aviation.
