Alfons Anker studied in Berlin and worked as an architect there. During World War I he was confronted with the lack of material and money. He was responsible to built temporary constructions such as shelters and hospitals. After 1918, becoming technical director at the Berlin Charlottenburg University, he focussed on mudbrick constructions as a natural and low-cost procedure. With his knowledge and work as an expert for buildings, he received further teaching assignments, including at the Bauhaus in Weimar and Dessau.
He was a member of the Association of German Architects (BDA) and worked together with the two architects Hans Luckhardt and Wassili Luckhardt in one office from 1923 until 1934. Because of his Jewish origins Anker had to leave the office. He did not succeed to work in Germany, but he also vanished to leave to the UK. At the end he emigraded to the family of his daughter in Stockholm, Sweden in 1939. In Sweden he co-operated with Swedish architects. After World War II he managed to co-design a big hospital in Berlin. He died in Stockholm.
