[Photographer, politician, and propagandist, b. 1889, Erfurt, Germany, d. 1940, Paris.]
Photography works upon the human eye: what is seen is reflected in the brain without the need for complicated thought. In this way the bourgeoisie takes advantage of the mental indolence of the masses and does good business as well. 
Photography has become an outstanding and indispensable means of propaganda in the revolutionary struggle.
