Mabel Normand was the first great comedienne of American cinema and one the most important -- and popular -- American silent film actresses. By the time she first showed up at the Biograph studio in 1910, Normand was already a "Gibson Girl" (a model for illustrator Charles Dana Gibson) and a champion swimmer, and she was not yet 18. Biograph published a photo of Normand with the phony name "Muriel Fortescue," leading some sources to believe this her real name, but nevertheless it was Mabel Normand. She was from a French Canadian family and born on Staten Island on November 9, 1892. Normand worked for Biograph only a few months, then joined Vitagraph for about a year while the Biograph Company wintered out West. After they returned, so did she, working under the direction of D.W. Griffith. Griffith cast Normand as the "second girl" in melodramas and in tomboy roles; Griffith's protégé, Mack Sennett, primarily made comedies and would exploit Normand's natural comic abilities and athleticism through casting her in the lead. A Dash Through the Clouds (1912) featured Normand escaping with her beau in a new gadget, a Wright Brothers-styled airplane. This, and other, short comedies made by Sennett helped establish Mabel Normand as a girl who could take care of herself -- willful, powerful, and seemingly without fear.
Sennett broke with Biograph to found Keystone Comedies, and Normand joined him in California; she starred in the first Keystone, The Water Nymph, released in September 1912. Apparently, a personal relationship between Sennett and Normand blossomed about this time as well, and though it was once the source of a popular musical, Mack and Mabel, the true nature of their relationship remains unclear. Normand was the Sennett studio's most significant female star, and as Sennett also discovered and introduced Gloria Swanson, Phyllis Haver, Betty Compson, and Carole Lombard, that's saying a lot. Normand also began to direct in 1914, although more out of necessity than any artistic need. One reason Charlie Chaplin was allowed to direct so early in his Keystone career was that he objected to taking direction from Normand, complaining about it to Sennett.
