Some Austrian filmmakers had already emigrated and begun careers in the United States by this time. Erich von Stroheim and Josef von Sternberg were just two of the natives of Austria who contributed to the early success of Hollywood. Lesser known filmmakers who began their career in the US were for example Henry Lehrman, who staged a few hundred slapstick movies, including the first four movies starring Charlie Chaplin. The founder of Fox Film Corporation, William Fox (born as Wilhelm Fuchs) and the first independent producer in Hollywood, Sam Spiegel, were also native Austrians, born as German speaking Jews in Austria-Hungary. The co-founder of Metro-Goldwyn-Mayer, Marcus Loew, was born as son of Jewish emigrants of Austria-Hungary.
