Wilson Mizner 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 part of the failed project of his older brother Addison to create a new resort in Boca Raton, Florida. He and Addison are the protagonists of Stephen Sondheim's musical Road Show.

Brown Derby was a chain of restaurants in Los Angeles, California. The first and best known was shaped like a derby hat, an iconic image that became synonymous with the Golden Age of Hollywood. It was opened by Wilson Mizner in 1926. The chain was started by Robert H. Cobb and Herbert K. Somborn in the 1920s. The original Brown Derby restaurants had closed or had been converted to other uses by the 1980s, though a Disney-backed Brown Derby national franchising program revived the brand in the 21st century. It is often incorrectly thought that the Brown Derby was a single restaurant, and the Wilshire Boulevard and Hollywood branches are frequently confused.
