Wilson Mizner (May 19, 1876 – April 3, 1933) was an American playwright, raconteur, and entrepreneur. His best-known plays are The Deep Purple, produced in 1910, and The Greyhound, produced in 1912. He was manager and co-owner of The Brown Derby restaurant in Los Angeles, California, and was affiliated with his brother, Addison Mizner, in a series of scams and picaresque misadventures that inspired Stephen Sondheim's musical Road Show (alternately known as Wise Guys, Gold! and Bounce).
