Erwin Freundlich
1885–1964
A pioneering astronomer who worked closely with Albert Einstein, he helped turn bold ideas about relativity into tests that could be checked against the sky. His career carried him from Germany to Turkey, Czechoslovakia, and Scotland as political upheaval reshaped Europe.

The foundations of Einstein's theory of gravitation
by Erwin Freundlich
About the author
Born in Biebrich, Germany, in 1885, Erwin Finlay-Freundlich became known for trying to test Einstein’s theory of general relativity through astronomy. He studied in Germany, worked with leading scientists of his day, and became one of the early researchers to focus on effects such as the bending of light and gravitational redshift.
His career was deeply shaped by both science and history. He directed and helped build research institutes in Potsdam, Istanbul, and Prague, and after leaving Nazi Germany he later settled in Scotland, where he became professor of astronomy at the University of St Andrews and led its observatory.
Freundlich died in 1964, but he remains an important figure in the story of modern astrophysics: a scientist who pushed hard to connect theory with observation, even when the evidence was difficult to capture with the tools of his time.
