«Ruttmann was born in Frankfurt am Main on December 28, 1897. He studied architecture in Zurich and then painting in Munich. [...] In ‹Berlin. Die Sinfonie einer Großstadt› he applied the principles of his abstract studies and film montage to realistic photographs from the city of Berlin. [...] After ‹Berlin› he turned to sound experiments and was eventually able to make ‹Melodie der Welt›, a Tobis film commissioned by Hapag-Lloyd and the first fulllength German sound film.

Beginning in 1934 he was employed as a director by UFA and made cultural, industrial, commercial, and propaganda films. On July 15, 1941, he died in Berlin after an operation.»
