Canadian-American physicist who was born in Ridgeway, Ontario, on May 16, 1919 and became a naturalized American citizen. With Rebka, he first carried out an experiment using the Mössbauer effect to test the predictions of general relativity. An emitter was set up on the top of a building and an absorber at the bottom. A frequency shift was observed which was in excellent agreement with the prediction of general relativity (Eisberg and Resnik 1985, p. 588).
