Edwin Hubble was born in Marshfield, Missouri in 1889, to an insurance executive. As a child Edwin loved reading science fiction novels. He received his first telescope at the age of 8, made by his grandfather. He moved to Chicago when he was ten years old. Hubble was a fine student as well as an athlete. He excelled in sports such as boxing and basketball. He was awarded a scholarship during high school and he paid his expenses by teaching and working during the summers. When Hubble received a scholarship to study at oxford he studied Roman and English Law and in 1913 he returned home and started practicing law in Kentucky.
He was hired by New Albany High School in the autumn of 1913 to teach Spanish, Physics and Mathematics, and to coach basketball. When the term ended in 1914 he decided to study astronomy from Yerkes Observatory. In 1917, he received a doctorate degree in astronomy from the University of Chicago. While in university he was recruited by California's Mount Wilson Observatory to help complete the construction of its Hooker telescope. Before beginning the new position Hubble completed a doctorate in astronomy, enlisted in the U.S. Army and served a tour of duty in World War I.
Using the Hooker 100-inch reflector on Mount Wilson, Hubble found that the Andromeda nebula, a cloudy patch in the sky, was so far away it could not be within our own galaxy. This illustrated that the Milky Way is just a small object within the universe. Later, by examining the light of distant galaxies, he showed that the universe is expanding, and that everything in it is moving away from everything else. In the early mid-1920s, Hubble began conducting new research with Milton Humason, on the galaxies' spectral shifts and unique distances. He and Humason published their research in 1929, theorizing that red shifts in galaxies' light emissions move at a linear rate to the distance between them. This means that galaxies are
