The first generation of animators in the late 1910s included Ōten Shimokawa, Jun'ichi Kōuchi and Seitaro Kitayama, commonly referred to as the "fathers" of anime. Propaganda films, such as "Momotarō no Umiwashi" (1943) and "" (1945), the latter being the first anime feature film, were made during World War II. During the 1970s, anime developed further, with the inspiration of Disney animators, separating itself from its Western roots, and developing distinct genres such as mecha and its super robot subgenre. Typical shows from this period include "Astro Boy", "Lupin III" and "Mazinger Z". During this period several filmmakers became famous, especially Hayao Miyazaki and Mamoru Oshii.
