Mostly recognized for his lithographies exploring the proletarian environment of Berlin, Heinrich Zille also practiced photography as an amateur - his work in the discipline was only discovered in 1966 as he had never published his pictures. Between 1882 and 1910, influenced by the pictorial movement, he used photography to memorize visual information but also to enhance his drawings. Heinrich Mille thus strolled around Berlin, observing the intimacy and habits of ordinary people. As his illustrations were very daring and sometimes gruesome - highlighting lack of hygiene, promiscuity within families that led to sex scenes in front of children, violence, death,…his photographies delivered a more vibrant domesticity - the rare documentation of a working-class community. While the drawings were caricatural, his images resembled more a sincere and modernist social protest.
