Albrecht Viktor Blum

German director with Czech roots created poetic compilation, avant-garde, and social documentary films. Born 1888 in Brno under the Austro-Hungarian Empire, he began working in film in Germany in the 1920s, where he shot most of his films. In 1933, he emigrated to Czechoslovakia, where he worked as a theater actor in Liberec. In 1936, he departed for Spain and from there to Mexico. Most of his films were produced by the leftist film companies Prometheusfilm and Weltfilm. Of the perhaps thirty films that he directed (he contributed to many more as editor or cinematographer), only six have survived.
