Highest Honors for Game-Changing Innovation

In 1929, President Herbert Hoover presented the Collier Trophy to Joseph Ames, chairman of the NACA, for the development of low-drag cowling for radial air-cooled aircraft engines. The Collier has been awarded annually since 1911 by the National Aeronautic Association ''for the greatest achievement in aeronautics or astronautics in America, with respect to improving the performance, efficiency, and safety of air or space vehicles.''
