Diamond Tooth Lil was an American cultural figure popular in the early 20th century as an icon of wealth and libertine burlesque. Several individuals called themselves "Diamond Lil" or "Diamond Tooth", creating an amalgamated legacy clouded by myth. These individuals include a vaudeville entertainer in the Yukon during the 1890s Klondike Gold Rush, a madam in the American West during the early 1900s, and the titular character of Mae West's Diamond Lil, who embodied these traits and popularized the name in the 1920s.[1]
