Charles Reilly wrote about Erich Mendelsohns' De La Warr Pavilion in the Architect's Journal of February 1934.

"The straightforward spaciousness of the interiors and the great spatial staircase gracefully mounting in their glass cylinders are things we have all dreamed about but none of us have done on their scale or with their sureness of touch. Thank goodness we still open our gates a little now and then to foreigners and make them members of our community."

Now undergoing a renovation, it is arguably one of Britains' best loved modernist buildings.

Erich Mendelsohn: De La Warr pavilion, Bexhill on Sea, 1933-4. Einstein Observatory, Potsdam 1924

At his Einstein tower of 1924 in Potsdam, expressionism carries echoes of Gaudi's playful anthropocentrism. Recently photographed by Hiroshi Sugimoto, it is perhaps surprising that as the tribute of one Jewish intellectual to another it survived the ravages of the German dictatorship and post-war East German regime.
Erich Mendelsohn was born in Allenstein, East Prussia in 1887. From 1910 to 1912 he studied under Theodor Fischer at the Technische Hochschule. Five years later he was driving a Red Cross ambulance for the German army on the Russian front. Extant from those years are Mendelsohn's sketches of modernist architecture, sent in letters from Russia. Among these is a design for a very unusual tower which was to prove Einstein's theory of relativity by measuring the sun's spectral lines.

"Armed only with cameras, sketchpads and a rough map, we set off to find the observatory. The tower, completed in 1924 as a facility for Albert Einstein to conduct astrophysical research, had been restored just months before our visit after over fifty years of neglect. The trek turned into an adventure of its own when we found ourselves somewhat lost. We made a shortcut through a cemetery to find a 10-foot-tall fence separating us from the gates to the grounds were the tower was located. We fashioned a crude ladder out of debris and scaled the barrier. Once through the gates, we followed a winding road through the grounds. The setting was a mixture of academic buildings and scientific structures set amongst trees and seemed meant for the endeavor of learning. Around a final corner, framed perfectly through the trees, we had our first look at the tower.
Our timing could not have been better. The late afternoon sun, on an almost clear day colored a long, quiet afternoon with Mendelsohn’s masterpiece. It was a joy to draw. Although the tower is completely symmetrical, it is not at all static. Its forms are soft, curved and folded planes that intersect with supreme grace. In the sunlight, the creamy color of the stucco-like skin accentuates the tower’s dramatic form."
