Dudley Robert Herschbach is an American chemist at Harvard University. He was awarded the Noble Prize in Chemistry (1986) for the development of a molecular cross beam technique which helps the study of chemical reactions. His research involves molecular stereodynamics, measurement and analysis of vector properties of reaction dynamics. He has also experimented with catalytic supersonic expansion reaction, dimensional scaling, and molecule orientation in collision stereodynamics. Herschbach was born in San Jose, California on June 18, 1932. He received his B.S. degree in Mathematics (1954) and M.S. in Chemistry (1955) at Stanford University, followed by an A.M. degree in Physics (1956) and Ph.D. in Chemical Physics (1958) at Harvard. His awards include Pure Chemistry Prize of ACS (1965), Linus Pauling Medal (1978), Michael Polanyi Medal (1981), Irving Langmuir Prize of APS (1983), National Medal of Science (1991), Jaroslav Heyrovsky Medal (1992), Sierra Nevada Distinguished Chemist Award (1993), Kosolapoff Award of the ACS (1994), William Walker Prize (1994) and the Council of Scientific Society President’s Award for Support of Science (1999).
