Robert S. Mulliken was born on June 7, 1896 in Newburyport, MA. He attended the Massachusetts Institute of Technology and the University of Chicago receiving his Ph. D. in 1921. He was exposed to quantum theory by Robert A. Millikan while at the University of Chicago and continued his post-doctoral studies with E.C. Kemble at Harvard where he also became acquainted with Robert Oppenheimer, Harold Urey and John C. Slater. Trips to Europe in 1926 and 1927 allowed him to meet with Erwin Schrodinger, Paul Dirac and Werner Heisenberg among other luminaries. After a stint teaching at NYU he returned to the University of Chicago where he spent the remainder of his career.
