 During the late 1890s and early 1900s, Cooper performed "rush work" filming and developing topical subjects, such as the 1898 launch of the "Albion" (for Acre), the 1902 Coronation of King Edward VII and Queen Alexandra (for the Biograph Company) and the 1903 Grand National among others.Dutch researcher Tjitte de Vries, based on later reports by Cooper and his daughter Audrey Wadowska, controversially claims that during this time the filmmaker also produced the "Animated Matches" series of films more commonly dated to 1914 and the GRG-Series of films more commonly attributed to George Albert Smith.Continuing to live at London Road with his mother and siblings and work as a cameraman, he began to think about establishing his own company following his father's death in 1901.
