This entry from Encyclopedia Brittanica's Guide to Black History features Moms Mabley, an American comedian who was one of the most successful black vaudeville performers. She modeled her stage persona largely on her grandmother, who had been a slave. Wise, clever, and often ribald, Mabley dressed in frumpy clothes and used her deep voice and elastic face (and, in later years, her toothlessness) to great effect. This site, rich in detail and breadth of coverage, includes a wealth of information on other notable African Americans, important events, and much more.
