Herschbach is a Fellow of the American Academy of Arts and Sciences, the National Academy of Sciences, the American Philosophical Society and the Royal Chemical Society of Great Britain. In addition to the Nobel Prize in Chemistry, he has received a wide variety of national and international awards. These include the National Medal of Science, the ACS Award in Pure Chemistry, the Linus Pauling Medal, the Irving Langmuir Award and the American Institute of Chemists Gold Medal.
Herschbach was born in San Jose, California on June 18, 1932. The eldest of six children, he grew up in a rural area. He graduated from Campbell High School, where he played football. Offered both athletic and academic scholarships to Stanford University, Herschbach chose the academic. His freshman advisor, Harold S. Johnston, hired him as a summer research assistant, and taught him chemical kinetics in his senior year. His master's research involved calculating Arrhenius A-factors for gas-phase reactions. Herschbach received a B.S. in mathematics in 1954 and an M.S. in chemistry in 1955 from Stanford University.
Herschbach then attended Harvard University where he earned a A.M. in physics in 1956 and a Ph.D. in chemical physics in 1958 under the direction of Edgar Bright Wilson. At Harvard, Herschbach examined tunnel splitting in molecules, using microwave spectroscopy. He was awarded a three-year Junior Fellowship in the Society of Fellows at Harvard, lasting from 1957 to 1959.
In 1959, Herschbach joined the University of California at Berkeley, where he was appointed an Assistant Professor of Chemistry and became an Associate Professor in 1961. At Berkeley, he and graduate students George Kwei and James Norris constructed a cross-beam instrument large enough for reactive scattering experiments involve alkali and various molecular partners. His interest in studying elementary chemical processes in molecular-beam reactive collisions challenged an often-accepted belief that "collisions do not occur in crossed molecular beams". The results of his studies of K + CH3I were the first to provide a detailed view of an elementary collision, demonstrating a direct rebound process in which the KI product recoiled from an incoming K atom beam. Subsequent studies of K + Br2 resulted in the discovery that the hot-wire surface ionization detector they were using was potentially contaminated by previous use, and had to be pre-treated to obtain reliable results. Changes to the instrumentation yielded reliable results, including the observation that the K + Br2 reaction involved a stripping reaction, in which the KBr product scattered forward from the incident K atom beam. As the research continued, it became possible to correlate the electronic structure of reactants and products with the reaction dynamics.
In 1963, Herschbach returned to Harvard University as a professor of chemistry. There he continued his work on molecular-beam reactive dynamics, working with graduate students Sanford Safron and Walter Miller on the reactions of alkali atoms with alkali halides. In 1967, Yuan T. Lee joined the lab as a postdoctoral student, and Herschbach, Lee, and graduate students Doug MacDonald and Pierre LeBreton began to construct a "supermachine" for studying collisions such as Cl + Br2 and hydrogen and halogen reactions.
His most acclaimed work, for which he won the Nobel Prize in Chemistry in 1986 with Yuan T. Lee and John C. Polanyi, was his collaboration with Yuan T. Lee on crossed molecular beam experiments. Crossing collimated beams of gas-phase reactants allows partitioning of Energy among translational, rotational, and vibrational modes of the product molecules—a vital aspect of understanding reaction dynamics. For their contributions to reaction dynamics, Herschbach and Lee are considered to have helped create a new field of research in chemistry. Herschbach is a pioneer in molecular stereodynamics, measuring and theoretically interpreting the role of angular momentum and its vector properties in chemical reaction dynamics.
He is a board member of the Center for Arms Control and Non-Proliferation and was the chairman of the board for Society for Science & the Public from 1992-2010. Herschbach is a member of the Board of Sponsors of The Bulletin of the Atomic Scientists. In 2003 he was one of 22 Nobel Laureates who signed the Humanist Manifesto.
Although still an active research professor at Harvard, he joined the Texas A&M University faculty September 1, 2005 as a Professor of Physics, teaching one semester per year in the chemical physics program. As of 2010, he holds the title of Professor Emeritus at Harvard, and remains well known for his involvement as a lecturer and mentor in the Harvard research community. He and his wife Georgene Herschbach also served for several years as the co-Masters of Currier House, where they were highly involved in undergraduate life in addition to their full-time duties.
Herschbach's wife, Georgene Herschbach, served as the Associate Dean of Harvard College for Undergraduate Academic Programs. Prior to retirement in 2009, she chaired Harvard College's influential Committee on Undergraduate Education.
In Oct. 2010, Herschbach participated in the USA Science and Engineering Festival's Lunch with a Laureate program where middle and high school students will get to engage in an informal conversation with a Nobel Prize–winning scientist over a brown-bag lunch. Herschbach is also a member of the USA Science and Engineering Festival's Advisory Board. Furthermore, Herschbach has participated in the Distinguished Lecture Series of the Research Science Institute (RSI), a summer research program for high school students held at MIT.
Professor Herschbach publicly endorsed Hillary Clinton for President in 2016.
