Milton L. Humason
From Wikipedia, the free encyclopedia
Milton Lasell Humason (August 19, 1891 – June 18, 1972) was as American astronomer. He was born in Dodge Center, Minnesota.
He started out as a janitor at the Mount Wilson Observatory in 1917, but soon became night assistant. As a professional, he became known as a meticulous observer, obtaining photographs and spectrograms. His observations played a major role in the development of physical cosmology, including assisting Edwin Hubble in formulating Hubble's law. He retired in 1957.
He discovered Comet C/1961 R1 (Humason), notable for its large perihelion distance.
Due to merest chance, Humason missed discovering Pluto. Eleven years before Clyde Tombaugh, Humason took a photograph in which the image of Pluto fell on a defect in the photographic plate and was not detected.
Much of the work Humason performed was actually credited to Hubble, the two of which worked together for many years.
He died in Mendocino, California.
