Edwin Powell Hubble, hero of 20th century astronomy, was an American Astronomer. He lived between November 20, 1889 and September 28, 1953, who is famous for the discovery of the existence of Galaxies other than the Milky Way and galactic Red Shift. Discovery that the loss in frequency -- the Red Shift -- observed in the spectra of light from other galaxies increased in proportion to a particular galaxy's distance from Earth. This relationship became known as "Hubble's Law." Hubble's findings fundamentally changed the scientific view of the universe. Hubble noted the Doppler Shift interpretation of the observed Red Shift that had been proposed earlier by Vesto Slipher, and that led to the theory of the metric expansion of space. He tended to believe the frequency of any beam of light could, by some so far unknown means, be diminished ever stronger, the longer the beam travels through space. Hubble then served in the US Army in World War I, and he quickly advanced to the rank of major. In 1919, Hubble was offered a staff position in California near Pasadena, where he remained on the staff until his death. Hubble experienced a heart attack in July 1949. He died of Cerebral Thrombosis (a spontaneous blood clot in his brain) on September 28, 1953, in San Marino, California.
