 Albert Abraham Michelson - Wikipedia, the free encyclopedia
Albert Abraham Michelson, (pronunciation anglicized as "Michael-son", December 19, 1852 - May 9, 1931), was a Prussian-born American physicist known for his work on the measurement of the speed of light, and especially for the Michelson-Morley experiment.
Michelson died with only 36 of the 233 measurement series completed and the experiment was subsequently beset by geological instability and condensation problems before the result of 299,774±11 km/s, consistent with the prevailing electro-optic values, was published posthumously in 1935.
Michelson continued to "refine" his method and in 1883 published a measurement of 299,853±60 km/s, rather closer to that of his mentor.

 ALBERT ABRAHAM MICHELSON
      Albert Michelson revolutionized science by measuring the speed of light with his interferometer and proving that there was, in fact no such thing as Ether.
Figure 1:The Michelson interferometer consists of a half-transparent mirror that divides a light beam into two equal parts (A and B), one of which is transmitted to a fixed mirror and the other of which is reflected to a movable mirror.
With this knowledge Michelson goal was to use the sensitivity of his interferometer “to measure the Earth’s velocity against ether….

 Albert Abraham Michelson 1852-1931
Albert A. Michelson's background, which seems odd to modern eyes, was not surprising in his own times.
Michelson later acknowledged the importance of Einstein's work, but to the end of his life he could never believe that light was not a vibration in some sort of ghostly ether.
This experiment of Michelson and Morley was quickly recognized as the most striking and significant of several different kinds of attempts to measure the ether, which together prepared the ground of doubts and opinions among European physicists from which Einstein's theory of relativity sprang.
