Autographs of Ed Yost
Paul Edward Yost (June 30, 1919 – May 27, 2007) was the American inventor of the modern hot air balloon and is referred to as the "Father of the Modern Day Hot-Air Balloon." He worked for a high-altitude research division of General Mills in the early 1950s until he left to establish Raven Industries in 1956, along with several colleagues from General Mills.
Born on a farm seven miles south of Bristow, Iowa, to Charles L. Yost and Fleta Ferne Burman Yost, Paul Edward Yost first became involved in lighter-than-air ballooning when he leased his single-engine plane to General Mills to track their gas balloons. He became a senior engineer in the development of high-altitude research balloons.
In the 1950s, Yost's own interests turned toward reviving the lost practice of manned hot-air ballooning. This technology had first been invented in France in the late 18th century by pioneers led by the Montgolfier brothers, but under the Montgolfier system, the balloon's air was heated by a ground fire prior to the balloon being released. The inherent danger of this type of balloon flight led to the system being abandoned when hydrogen and later helium became available.
