How a visionary architect helped design the firebombing of Berlin

In short: Erich Mendelsohn was a pioneer of expressionist architecture who defined the look of the Weimar Republic. Yet, his career took a dark turn in exile. While teaching in the United States, he used his expertise in German housing to help the U.S. Army simulate targets for devastating aerial attacks.

Born in 1887 in East Prussia, Mendelsohn rose to prominence through his dynamic, functionalist designs. His early reputation was cemented by the Einsteinturm in Potsdam and the innovative hat factory in Luckenwalde. By the 1920s, his practice in Berlin was a powerhouse, employing dozens of staff and shaping the urban landscape with iconic department stores and cinemas that pioneered Art Deco and Streamline Moderne styles.

The rise of the Nazis in 1933 forced Mendelsohn to flee Germany, where his assets were seized and his professional credentials stripped. After a period in England, where he collaborated on notable projects like the De La Warr Pavilion, he eventually settled in the United States in 1941. His status as an immigrant initially limited his professional activities, but he eventually served as a government consultant.

In 1943, Mendelsohn provided critical technical assistance to the U.S. military. He worked alongside Standard Oil to construct 'German Village,' a series of precise replicas of typical working-class residential estates. This project was not merely architectural; it was a strategic effort to master the specific construction methods of German buildings, providing the military with the necessary data to optimize the firebombing of Berlin.

After the war, Mendelsohn relocated to San Francisco, focusing his final years on projects for Jewish communities, including synagogues and hospitals. His legacy remains complex: he is remembered as a master of modern architecture who defined the aesthetic of a bygone era, yet his final contributions to the war effort highlight the tragic intersection of his technical genius and the geopolitical conflicts of his time.
