| Einstein with Hubble at Mount Wilson |
Although Albert Einstein’s second wife, Elsa, didn’t
understand what he did, she was immensely proud of him for doing it. One sunny
day in January 1931, while Einstein played with the controls of the 100-inch
reflector telescope at the Mount Wilson Observatory near Pasadena, someone
explained to Elsa that astronomer Edwin Hubble had used this equipment to
discover the size and shape of the universe. She replied, “Well, my husband
does that on the back of an old envelope.”
