American inorganic chemist
Harry Barkus Gray (born November 14, 1935) is the Arnold O. Beckman Professor of Chemistry atCalifornia Institute of Technology .[ 2]
Gray received his B.S. in chemistry fromWestern Kentucky University in 1957. He began his work ininorganic chemistry atNorthwestern University , where he earned his Ph.D. in 1960 working underFred Basolo andRalph Pearson . He was initiated into the Upsilon chapter ofAlpha Chi Sigma at Northwestern University in 1958.[ 3] After that, he spent a year (1960–61) as anNSF Postdoctoral Fellow at theUniversity 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 Fellowship at theUniversity of Copenhagen , he relocated to New York City to take up a faculty appointment atColumbia 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 atCalifornia Institute of Technology , and founding director of theBeckman Institute .[ 7] He also served on the Physical Sciences jury for theInfosys 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: Dave Dooley atUniversity of Rhode Island , Greg Geoffroy atIowa State University ,Holden Thorp atUniversity of North Carolina at Chapel Hill , andMark Wrighton atWashington University in St. Louis .[ 8]
Gray's interdisciplinary research program addresses a wide range of fundamental problems ininorganic chemistry ,biochemistry , andbiophysics .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 inorganicredox reagents. Early research by his lab members showed that details of the internal structures of the proteins dominate the ET rates.[ 10] Current research is aimed at understanding how intermediate protein radicals accelerate long-range ET. In collaboration withJay R. Winkler of theBeckman Institute at Caltech they have developed new techniques for measuring ET rates in crystals of Ru-, Os-, and Re-modifiedazurins , as well as crystals of Fe(III)-cytochrome c doped with Zn(II)-cytochrome c.[ 11] This method of integratingphotosensitizers into protein crystals has provided a powerful new tool for studying biochemical reaction dynamics.[ 12] The Gray/Winkler group is also using ET chemistry to probe the dynamics ofprotein folding incytochrome c .[ 13]

His accolades include:
He was awarded theWolf Prize in Chemistry in 2004 for his pioneering work inbioinorganic chemistry , unraveling novel principles of structure and long-rangeelectron 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 betweenchemistry andbiology . As a pioneer of the important and thriving field ofbioinorganic 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]
