"Hans Wittwer (4 February 1894–19 March 1952) was a Swiss architect who worked in Germany and who taught architecture at the Bauhaus art school in Dessau. He was a proponent of functionalist architecture; the idea that form follows function. He worked with the Bauhaus director Hannes Meyer both at the school and in a joint architectural practice in Basel. He also taught at the Kunstgewerbeschule Burg Giebichenstein in Halle." - (en.wikipedia.org 30.01.2020)
