Blutwäsche bei einem Hund [Archivtitel]

Documentation of an early dialysis experiment by Prof. Georg Haas at the Medical Clinic Gießen. Using collodion tubes, Prof. Haas and two colleagues perform a "blood purification" on a dog in the laboratory.

Since the 1910s, Oskar Barnack, the inventor of the Leica, has captured events around Wetzlar on film with his self-constructed film camera. He documented flood disasters, city festivals, medical experiments, sporting events and the company where he was employed as chief designer: the Optical Works Ernst Leitz in Wetzlar. His films form the basis of a film archive in which local history has the same place as the effects of great historical events.
