Siegfried Ebeling

From 1924 to 1925 he studied at the Bauhaus in Weimar under Wassily Kandinsky and Marcel Breuer, with whom he was also friends. In 1926, he published his architectural theory paper “Der Raum als Membran” (“Space as Membrane”), which caused a great stir among experts. In it, he described the house wall as a semi-permeable separating layer. According to his conviction, a building must also always have the possibility to breathe, so that an exchange between inside and outside is created.
