This book is devoted to Hardt-Waltherr Hämer as a salute to the architect, town planner, Bauhaus director, teacher and journalist who played a central role in German post-war architecture. Five authors - architecture critics, town planners, builders - present a portrait of this famous figure in German architectural history, who was once described by a colleague as a "city seducer" and who, in everything he did, had the city on his mind.
