Clinton "Santy" Runyon (July 4, 1907 – April 4, 2003) was an American saxophonist and flautist as well as a designer and manufacturer of mouthpieces for woodwind instruments.
At the Chicago Theater, he worked with Bob Hope, Bing Crosby, Edgar Bergen, Betty Grable and other show business notables.
Through its doors passed such jazz legends as Charlie "Bird" Parker,[3] Paul Desmond, Harry Carney, Lee Konitz, and Sonny Stitt.
Runyon had students in most of the big bands of the era, including those of Benny Goodman, Count Basie, Cab Calloway, and Duke Ellington.
From this period came the Runyon Custom model mouthpiece, available with a removable "spoiler," or baffle, that altered tonal and dynamic characteristics, the Quantum, and the Bionix, engineered for ease of playing in the altissimo register.
During this period he pioneered the use of Delrin which, due to its high rigidity and machinability, is suitable for dimensional copies of metal mouthpieces (XL and Quantum).
