German astronomer, a pupil of Felix Klein, and a working associate of Albert Einstein, who introduced experiments for which the general theory of relativity could be tested by astronomical observations based on the gravitational redshift.

Freundlich researched the deflection of light rays passing close to the Sun. He proposed an experiment, during an eclipse, to verify the validity of Einstein's theory of general relativity. Freundlich's demonstration would have proven Newton's theories incorrect. He did conduct inconclusive tests on the prediction by Einstein's theory of gravitation-induced red shift of spectral lines in the Sun, using the solar observatories he had constructed in Potsdam and Istanbul. In 1953, he proposed with Max Born an alternative explanation of the red shifts observed in galaxies by a tired light model.

Freundlich died in Wiesbaden on 24 July 1964, aged 79.
