Fred Gevalt is founder of The Air Charter Guide, a directory and information business that serves the worldwide market of on demand aircraft charter. Gevalt began the business in 1984 and sold it in 2005 to Prism Business Media, a spin off of K-III Communications, which later merged with Penton Media. A political activist, Gevalt cut his teeth on countering federal agency behavior in 1998 with a successful lawsuit against the Federal Aviation Administration on behalf of his air charter constituency. An avid pilot since returning from Vietnam in 1968, Gevalt has built airplanes himself, and currently flies aircraft for business as well as recreation. He graduated from Harvard College in 1972, and earned a Masters in Architecture in 1976.
