Named after The Brown Derby chain of restaurants in Los Angeles, California. The original restaurant opened in 1926 at 3427 Wilshire Boulevard and was iconic due to the building being shaped like a man's derby hat. The chain was started by Robert H. Cobb and Herbert Somborn (a former husband of film star Gloria Swanson).
