 The nickname "Ringsiedlung" came from the association of some of these architects with Der Ring collective.The open spaces were designed by the German modernist landscape architect Leberecht Migge.Unlike the other significant public housing projects of the time, which were produced under government cooperative Gehag sponsorship, the Siemensstadt was constructed by a private housing cooperative as worker housing for Siemens' nearby electrical factory, which employed 60,000 workers.
