Hans Richter was a German painter and filmmaker, known for his contributions to the Dada movement and abstract art. Born in 1888, he played a significant role in the early 20th-century avant-garde scene, experimenting with visual and cinematic techniques that challenged traditional forms of art. Richter's work often explored the relationship between movement and perception, particularly in his films like Rhythms 21. He was also involved in the development of kinetic art, which emphasizes motion as a fundamental aspect of artistic expression. Richter's innovative ideas continue to influence contemporary artists and filmmakers today.
