Robert S. Mulliken, codirector of the Laboratory of Molecular Structure and Spectra at the University of Chicago, has been named recipient of two separate awards in chemistry. The 1964 John Gamble Kirkwood Medal, honoring the late director of the Division of the Sciences at Yale, was presented to Dr. Mulliken in November by the Yale University Chemistry Department and the New Haven Section of the American Chemical Society. The 53rd Willard Gibbs Award is scheduled to be presented to him in May, during a dinner ceremony of the Chemical Society's Chicago Section. Both awards pay tribute to Dr. Mulliken's pioneering work in molecular chemistry.
