According to some texts, Hirsh led a disorderly life, maintaining little interest in preserving or completing his own work. In his later career, some of his film screenings were live events with multiple projectors. He treated films as malleable objects by constantly editing and re-editing them, using live music instead of pre-recorded soundtracks. According to several texts by
William Moritz, upon Hirsh's death in 1961 in Paris, the police found hashish in his apartment, and impounded all of Hirsh's property, including finished and unfinished films. When the police released the material three years later, many films and papers were missing. For his first film,
Divertissement Rococo (1951), and several subsequent films, he employed filmed oscilloscope imagery. In
Come Closer (1953), he acknowledged the then-current fad of
3-D film by layering multi-colored circular imagery, on 2 separate synched films for 3-D projection, intended to be viewed with 3-D glasses. This was later screened by Moritz and a few others as a single film, though it is correctly a 2-panel, 3D film. In
Gyromorphosis (1954), 7 min, made in Amsterdam, Hy Hirsh displays the kinetic qualities of the New Babylon structures of
Constant Nieuwenhuys. For
Chasse de touches ("The Chase of Brushstrokes", 1959), Hirsh animated layers of colored oils, and in
Autumn Spectrum (1957), used the movement of water and light in Amsterdam to create layers. In 1958 he filmed peeling walls and pieces of old posters in Paris for ''Defense d'Afficher
("Post No Bills"). In 1961, he scratched animated images over live-action footage for Scratch Pad,'' which incorporated imagery from previous films and found footage as well. ==Preservation==
