1927 Press Photo Albert A. Michelson-Scientist of University of Chicago

Pasadena, California---Doctor Albert A. Michelson internationally known scientist of the University of Chicago and the first American to be awarded the Noble Prize in Physics more than 20 years ago, recently arrived in Pasadena, California to complete life-long experiments on the speed of light and to test the so-called "ether drift" element of the relativity theory as advanced by Einstein. Fro experiments made with light thrown back and forth from the summit of Mount Wilson and Mount Baldy, 22-miles apart several years ago, Doctor Michelson calculated the velocity of light at 186,284 miles a second. For his new experiments, apparatus has been installed on Mount San Jacinto and Mount Wilson, 82 miles apart, and by throwing light between these two peaks he hopes to obtain a still more accurate check on his previous figures and arrive at a stated speed to be used by the entire scientific world. While in Pasadena, California at the Mount Wilson observatory, Doctor Michelson, who is 77-years-of-age, will repeat the famous Michelson-Morley experiment made 30 years ago to demonstrate that the earth is not drifting through the ether which scientists claim fills space, but is actually drifting with it, if there is any motion whatsoever.
