Visual music artists

Walter Ruttmann (28 December 1887 – 15 July 1941) was a German cinematographer and film director, an important German abstract experimental film maker, along with Hans Richter, Viking Eggeling and Oskar Fischinger. He is best known for directing the semi-documentary 'city symphony' silent film, with orchestral score by Edmund Meisel, in 1927, Berlin: Symphony of a Metropolis. His audio montage Wochenende (Weekend) (1930) is considered a major contribution in the development of audio plays.

He also wrote extensively on other visual music artists who worked with motion pictures, including James and John Whitney and Jordan Belson; Moritz also published on German cinema, Visual Music, color organs, experimental animation, avant-garde film and the California School of Color Music.
