This award, first presented in 1966, recognized “outstanding individual contributions to aviation safety, through basic design, device or practice.”
A retired U.S. Navy admiral and a Foundation president in the mid-1950s, de Florez was influential in the development of early flight simulators. He received the 1943 Collier Trophy — one of the most prestigious awards for aeronautical achievement in the United States — for his work in training pilots and flight crews. De Florez established a trust to support the award that carries his name and to provide each recipient with $1,000. The award includes a hand-lettered citation.
This award was discontinued in 2011.
