Hans Richter was a German painter, graphic artist, avant-gardist, film and animation experimentalist, and producer. He was greatly influenced by cubism in the 1910s.
Richter believed that the artist’s duty was to be actively political, opposing war and supporting the revolution.
Throughout his career, he claimed that his 1921 film Rhythmus 21 was the first abstract film ever created. However, this is simply not true. He was in fact preceded by German artist Walther Ruttmann, among others. Nevertheless, Richter’s film Rhythmus 21 is considered an important early abstract film by filmmakers and film scholars throughout the world.
