Freundlich reasearched 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. Freundlich demonstration would have proven Newton's theories incorrect. He did conduct inconclusive tests of Einstein's general relativity.
FinlayFreundlich was one of a family of seven children, five boys and two girls.
Freundlich was awarded a doctorate by the University of Göttingen for a thesis on analytic function theory in 1910.
Freundlich was interested in measuring the deflection in a light ray passing close to the sun since again Einstein's incomplete theory of relativity suggested that this test could be used to check the validity of the theory and show that Newton's theory was incorrect.
Freundlich was a working associate of Albert Einstein and introduced experiments for which the general theory of relativity could be tested by astronomical observations based on the gravitational redshift.
