Harry B. Gray

Harry Barkus Gray (born November 14, 1935) is the Arnold O. Beckman Professor of Chemistry at California Institute of Technology.^[2]

Career

Gray received his B.S. in chemistry from Western Kentucky University in 1957. He began his work in inorganic chemistry at Northwestern University, where he earned his Ph.D. in 1960 working under Fred Basolo and Ralph Pearson. He was initiated into the Upsilon chapter of Alpha Chi Sigma at Northwestern University in 1958.^[3] After that, he spent a year (1960–61) as an NSF Postdoctoral Fellow at the University of Copenhagen,^[4] where, along with Walter A. Manch, he collaborated with Carl J. Ballhausen on studies of the electronic structures of metal complexes.^[5][6]

After completing his NSF Postdoctoral Fellow at the University of Copenhagen, he relocated to New York City to take up a faculty appointment at Columbia University. He served as an assistant professor from 1961 to 1963 and as an associate professor from 1963 to 1965.

In 1966, he became the Arnold O. Beckman Professor of Chemistry at California Institute of Technology, and founding director of the Beckman Institute for Advanced Science and Technology.^[7] He also served on the Physical Sciences jury for the Infosys Prize from 2010 to 2013.

Gray also trained future leaders of several major science research universities. Four of his doctoral students became presidents or chancellors of University of Rhode Island, Iowa State University, University of North Carolina at Chapel Hill, and Washington University in St. Louis.^[8]

Research

Gray's interdisciplinary research program addresses a wide range of fundamental problems in inorganic chemistry, biochemistry, and biophysics. Electron transfer (ET) chemistry is a unifying theme for much of this research.^[9]

Over the past twenty-five years the Gray group has been measuring the kinetics of long-range ET reactions in metalloproteins labeled with inorganic

Wolf Prize

He was awarded the Wolf Prize in Chemistry in 2004 for his pioneering work in bioinorganic chemistry, unraveling novel principles of structure and long-range electron transfer in proteins.^[9][27]

Gray has made generative contributions to the understanding of chemical bonding of metal complexes, mechanisms of inorganic reactions, spectroscopy and magneto-chemistry of inorganic compounds. His study of the first trigonal prismatic complexes is one such example. Harry Gray's most significant work lies at the interface between chemistry and biology. As a pioneer of the important and thriving field of bioinorganic chemistry, he has made many key contributions, the most important of which is the development of fundamental understanding of electron transfer in biological systems, at the atomic level.^[28]
