(1921–83). German architect. As City Architect of Berlin in the 1960s he was a leading light in the conservation movement to save Berlin's heritage of stucco-fronted C19 apartments, but he was also a prime mover in the campaign to persuade Mies van der Rohe to return to Berlin and build the Nationalgalerie, which, arguably, with the Philharmonie by Scharoun, ignored the historic plan of the city in that area. He was responsible for some major developments, including low-density housing at Heiligensee (1975) and apartment-blocks at Märkisches Viertel, Wittenau, both in Berlin (1970).
