No. 2988: MILTON HUMASON
by Andy Boyd
Today, quiet persistence. The University of Houstonís College of Engineering presents this series about the machines that make our civilization run, and the people whose ingenuity created them.
Edwin Hubble is without question one of the most famous astronomers in history. With stellar credentials from the University of Chicago, Hubble not only discovered the universe is expanding — leading to the Big Bang Theory — but he quantified the rate of expansion through a law that bears his name. Today, however, we donít focus our sights on the luminary Hubble, but instead on his collaborator, Milton Humason.

Humason was born in 1891 in the tiny town of Dodge Center, Minnesota. At age fourteen his family moved to California, whereupon he attended camp at Mount Wilson. It was a period of great excitement as preparations were being made for the arrival of a new, massive telescope.

Enthralled by what he encountered, Humason left high school to work for a year, leading mule-powered wagons laden with building supplies up the mountain. One year stretched into five, at which point the young man met his wife-to-be, Helen Dowd. They married, and Humason took a job as a ranch foreman east of Los Angeles.
Humason never returned to high school nor any other school for that matter. But after seven years the call of the observatory proved too strong. When the observatoryís engineer, who also happened to be Humasonís father-in-law, told the twenty-six year old about a job as janitor, Humason jumped. It wasnít just a desire simply to be near the telescope. High in the mountains, tucked away from civilization, Humason knew that even an aspiring janitor could be called upon to help out with equipment.
And thatís exactly what happened. Humason became adept at manipulating the telescopes to take pictures — a meticulous process given the motion of the stars. Within three years Humason was promoted from janitor to staff, a controversial step given competition for the job and Humasonís lack of credentials. But Humason didnít disappoint. He was not only good with photography, but with the endless hours spent examining photographic plates looking for minute details.

Humason worked closely with Hubble for many years, providing much of the spadework contributing to Hubbleís success. But while Humason never achieved the stature of Hubble, he was nonetheless greatly respected by his peers. Hubble and Humasonís names appeared jointly on a long list of publications, and after decades of spending cool, dark evenings under the stars, Humason was appointed Secretary of the Observatory. Here he devoted much of his time to answering letters from people all over the world in all walks of life. His correspondence shows a man whose patience watching the stars translated into a cordial patience with the many viewpoints he encountered.
Humason retired in 1957 at the age of sixty-six, settling into a small town on the Northern California coast. There he and wife Helen lived together quietly and happily for their remaining years.
