Gustave Frohman (c. 1854 – August 16, 1930) was a theatre producer and advance man. He was one of three Frohman brothers who entered show business and he worked for most of his career alongside his brother, Charles Frohman. These two financed a number of theatre productions, often featuring African American actors. For instance, in 1878, they starred Sam Lucas in the first serious stage production of Uncle Tom's Cabin with a black man in the lead role.
