George S. Benton was born on September 24, 1917, in Oak Park, Illinois, and was raised in Chicago. His family had a diverse background, with his mother's family originating from Edinburgh, Scotland, and his father's family immigrating from Rega to Michigan when his father was three years old. Benton's original family name was Blumenstock, but he later changed it to George Benton. Benton's early education was at the University of California at Berkeley, where he was involved with the Department of Geography. However, he did not complete his Bachelor's degree there.
