The building was unlike anything in 1920s Germany: a curving, melted-looking solar observatory that one critic compared to an ungainly spaceship parked in the suburbs of Potsdam. Einstein said nothing as they walked. He said nothing on the stairs. He said nothing in the dome. Hours later, in a meeting with the building committee, he leaned over and whispered a single word: organic. Mendelsohn took it as the highest praise he ever received. Whether the moment really happened that way is a story the building has been telling about itself for a hundred years.

In 1911 Einstein had published the early version of his general theory of relativity, and one of its predictions involved a slight reddening of light from massive bodies - a gravitational red shift in the spectrum of the sun's surface. To test it required precision spectroscopy o...

Erich Mendelsohn was one of the founders of expressionist architecture in Germany, and the Einstein Tower was his first major commission - completed when a young Richard Neutra, later one of the great mid-century modernists in Los Angeles, was on his staff. Between 1917 and 1920 ...

Einstein had emigrated to America that same year; pictures of him were taken down and busts were officially melted. After the war it emerged that staff at the obs...

Einstein Tower: Still Watching the Sun

The actual signal was so small, and the turbulence on the sun's surface so disruptive, that the prediction was not cleanly verified until the 1950s. By then the Einstein Tower had pivoted ...
