Leon Norman Hefflin, Sr. (August 17, 1898 – November 20, 1975) was a pioneering African-American producer, director, business owner, furniture manufacturer, and entrepreneur. After losing his large and successful manufacturing business in the Depression he rebounded to produce the first and largest outdoor jazz entertainment event of its kind, the "Cavalcade of Jazz," in 1945. Held at Wrigley Field in Los Angeles, it was part of the Central Ave jazz scene, and showcased over 125 artists over 15 years.
