Walter or Walther Ruttmann (December 28, 1887, Frankfurt am Main, July 15, 1941, Berlin) was director, a screenwriter, a cinematographer and an editor.
Ruttmann created an impressionistic symphony with his experimental portrait of Berlin in 1927 Berlin, die Sinfonie der Großstadt. Before becoming a filmmaker in the early twenties while releasing advertising and animation films, Ruttmann was a painter and an architect.
His unique musical composition: Weekend is a pioneering work from the early days of radio, commissioned in 1928 by Berlin Radio Hour. In a collage of words, music fragments and sounds, Walter Ruttmann presented a radically innovative radio piece (Hörspiel) as an acoustic film of a Berlin weekend urban landscape.
