Hermann Häfker

Hermann Wilhelm Häfker (3 June 1873, in Bremen – 27 December 1939, in the Concentration Camp Mauthausen) was an important film theoretician as well as an acknowledged Esperantist and writer.

Häfker is considered the most important representative of the film reform movement in Germany.

He recognized early the cultural potential of cinema, but also the dangers of "low taste" resulting from commercial film production.

His presumably most successful book, Das Sternbilder-Buch, contributed to educating the youth to love of stars and astronomy.

Häfker's Weltgeschichte in einem Band (World History in one Volume) was banned by the Nazis.
