Pratt & Whitney Hall of Fame

Frank Gillette was known across the industry as the Father of the F119. He was the director of Advanced Military Engines and for over 36 years,  more than 55 including his time consulting.  Frank led the design, development, and production of the F119 from its earliest concepts, through first flight, and operational capability.

In retirement, Frank continued serving the company and the broader propulsion community through consulting, extensive teaching, and 21 years volunteering at the U.S. Air Force Academy. His contributions to propulsion, leadership within national organizations, and his numerous honors reflect a career that fundamentally shaped modern military aviation.

Leonard Hobbs was an engineer who helped bridge the era from early aviation into the jet age. Hobbs was instrumental in the development of radial engines throughout WWII and played a pivotal role in the creation of the J57 (the first axial‑flow twin‑spool turbojet and first engine to surpass 10,000 pounds of thrust). His work was recognized by the industry when he received the Collier Trophy in 1952.

The J57 went on to power 13 military applications and led to the JT3 for commercial service. Hobbs became Vice President of Engineering in 1944, later Vice Chairman of United Aircraft, and remained on the board until 1968. His innovations laid the groundwork for generations of propulsion advances.

Robert “Bob” Rosati was the driving force behind the creation of International Aero Engines (IAE). Bob was an engineer and convinced Pratt & Whitney, Rolls‑Royce, MTU of Germany, the Japanese Aero Engine Corporation, and Fiat/Avio to join together to create what became one of the most successful engine programs in the world — powering the Airbus A320 family.

Bob began as an experimental test engineer and went on to contribute to nearly every major commercial and military engine program of his era, including extensive work on the JT3D, TF33, TF30, JT9D, and PW2000 families. He later led billions in global engine sales and twice served as IAE’s President and CEO.

John Tirone was the Design Chief & Engineering Technical Fellow in Compression Systems Engineering. John was recognized by three independent nominations and his career represents the highest standards of technical leadership, innovation, and mentorship.

From Advanced Turbines in West Palm Beach to his roles as Design Lead, Chief, Manager, Subject Matter Expert, Fellow, and ultimately Technical Fellow, John played a central role in shaping 5th‑ and 6th‑generation platforms, as well as the GTF. He influenced design criteria, engineering standard work, and enterprise‑wide technology development.

Just as impactful is his mentorship — empowering engineers through trust, clarity, and quiet confidence. His leadership extended into academia, where he strengthened our partnerships with the University of Hartford and the University of Connecticut, ensuring that the next generation of engineering talent thrives. 

George Truitt was a  champion of Quality and Foreign Object Debris control. Working at the Columbus Engine Center, George was the FOD and Quality Trailblazer of Pratt & Whitney and established the gold standard for FOD programs — through daily audits, rigorous training, international engagements, and relentless commitment to continuous improvement.

His expectation for excellence elevated every cell he touched, and his leadership strengthened P&W’s reputation for quality. George’s impact on our FOD culture is still felt today.

James Young was the founder and first president of what we know today as Pratt & Whitney Canada. Under Young’s leadership, P&WC evolved from a service center for Wasp and Hornet engines into a manufacturing powerhouse — ultimately leading to the development of the revolutionary PT6, an engine that would power more than 130 types of aircraft.

His leadership extended through WWII, where he oversaw critical government contracts, and he remained with the company as chairman and as a board member for decades. His vision shaped an entire division of our company that continues to thrive globally.ircraft & Transport Corporation in 1932. With the formation of the United Aircraft Corporation in 1934, Mr. Brown was elected its president. The UAC and its subsidiary, the United Aircraft Manufacturing Corporation of which he was also President, are the parent companies of Pratt & Whitney, Chance Vought Aircraft, Sikorsky Aircraft and Hamilton Standard Propellers.​

​

Fredrick Rentschler was the founder and  the first president of Pratt & Whitney Aircraft.  He was born in Hamilton, Ohio where his family owned a tool making company.  After graduating from Princeton, he returned to the family business and learned the machinist's trade. Rentschler began his career in aviation during WWI , as an Army officer  overseeing the production of engines being built by Wright-Martin Aircraft Corporation. Following the war, Rentschler helped to organize the Wright aeronautical Corporation in Patterson, New Jersey and became its president. In 1924, he left Wright Aeronautical with the dream of establishing his own company to make the most reliable aircraft engine in the industry and the rest is history. 

Andy Willgoos was a founding member and head engine designer of Pratt & Whitney Aircraft.   

After World War I, Willgoos joined Rentschler and Mead at Wright Aeronautical Corporation in Patterson, N.J., where he was named chief designing engineer. In July 1925, he resigned from Wright, and he and mead set to work designing a radial engine in an improvised drafting room in Willgoos' garage. While the pair was designing the engine that would be the Wasp, Rentschler was in Hartford setting up Pratt & Whitney.  

After the success of the Wasp, Willgoos went on to design the Twin Wasp, the Wasp Junior, and the Hornet engines. 

George Mead was a founding member and the first vice president of Engineering at Pratt & Whitney Aircraft. 

 In 1925 when Rentschler established Pratt & Whitney Aircraft, mead resigned form Wright and went with the new company as vice-president in charge of engineering. While Rentschler was organizing the company during the summer of 1925, mead and Willgoos began work designing an air-cooled radial engine that would become the Wasp. When Pratt & Whitney became part of United Aircraft and Transport Corporation in 1929, Mead became Vice-President, and a member of the Executive board and Chairman of the Technical Advisory Committee. He later served as Vice President of United Aircraft Corporation and was the Chief Engineer. ​ 

Jack Borrup was a founding member and the first shop superintendent of Pratt & Whitney Aircraft operations. 

Borrup was also working for the Wright Aeronautical Corporation of Paterson, N. J., when he was asked to join new venture to build air‐cooled aircraft engines of a radical new design. He was known as a "crusty shop guy" and “one of the 'gosh darnedest' best superintendents that ever wore overalls". Many stories abound about shop superintendent Jack Borrup and his high-pitched lectures, often punctuated with strong Anglo-Saxon epithets. 

Don Brown was a founding member and first factory floor manager. When Pratt & Whitney Aircraft Company was formed in 1925, Don joined to become one of the original executives of the new engine manufacturing companies in the U.S. Mr. Brown was so extremely efficient at his job, he went from Factory Floor Manager to being elected Vice President of the company and later President. He was later elected to be Vice President and Director of the United Aircraft & Transport Corporation in 1932. With the formation of the United Aircraft Corporation in 1934, Mr. Brown was elected its president. The UAC and its subsidiary, the United Aircraft Manufacturing Corporation of which he was also President, are the parent companies of Pratt & Whitney, Chance Vought Aircraft, Sikorsky Aircraft and Hamilton Standard Propellers.​
