Biographical Sketch: The material in the William J. Yarber Papers relates to the career of Arthur L. Fortnoff. Arthur L. Fortnoff joined the Bell Aircraft Corporation on September 9, 1935, just two years after the company was founded. He worked in the helicopter sales division of the corporation and eventually rose to the position of Assistant to the Director of the Commercial Sales Department. Fortnoff spent 43 years as an employee of Bell and retired in 1970 as the oldest employee in terms in service. In 1971 Fortnoff founded the National Heliport Standards Committee (NHSC) to develop the use of helicopters and helicopter facilities in urban settings. He was the first executive director of the NHSC. Fortnoff was a firm believer in the potential of urban helicopter use and devoted time and effort to increase the visibility of urban heliports in the American conscious.
