Robert Gitt is Director of Preservation at the UCLA Film Archives. William Ault is Paper Print Archivist and in the 1950s was a pioneer in the transfer of paper prints to acetate film.

“Until 1915, motion pictures could only be copyrighted as still photographs...(on) paper rolls (which) were sent to the Library of Congress... The Adventures of Dollie had the distinction of being the first film directed by D.W. Griffith. While it had been widely written about in film history books, no good prints on motion picture film survived until it was copied from paper by UCLA last year. Mabel's Wilful Way is a Mack Sennett comedy, starring Mabel Normand, of course. On the Night Stage was one of the last feature films protected by paper print copyright registration. Although everyone knows that the Western form dates at least as far back as 1903 and The Great Train Robbery, it remained for William S. Hart to synthesize its elements into the kind of Western movie we still watch today. In that sense, Hart was as much a pioneer as the men whose exploits he celebrated on film, and he made an enduring contribution to the development of American myth.” Charles Hopkins
