Sanford received an A. B. from the University of Minnesota in 1905 and, after a year of high school teaching in Minnesota, came to Lick Observatory as an assistant to Richard H. Tucker. From 1908 to 1915, he was with Lick expeditions at San Luis, Argentina, determining positions of southern stars, and at Santiago, Chile, measuring radial velocities. Sanford returned to Lick in 1915 and completed a Ph. D. dissertation in 1917, working with  Heber Curtis.
