Gottfried Wilhelm "Billy" Bitzer (April 21, 1872 – April 29, 1944) was a pioneering American cinematographer notable for his close association with D. W. Griffith. In 2003, a survey conducted by the International Cinematographers Guild named him one of the ten most influential cinematographers in history. Bitzer, it is said, "developed camera techniques that set the standard for all future motion pictures."
