Robert A. Moss is the Louis P. Hammett Professor of Chemistry at Rutgers, the State University of New Jersey, New Brunswick, NJ. He received his Ph. D. with Professor Gerhard Closs (Chicago) and was a postdoctoral student with Professor Ronald Breslow (Columbia). Dr. Moss has been an A.P. Sloan Foundation Fellow, and a visiting professor or scientist at M.I.T., the University of Oxford, the Politechnika (Warsaw), the Weizmann Institute, the National Research Council of Canada, and the Hebrew University of Jerusalem. He has more than 350 scientific publications in the areas of reactive intermediates and chemistry in molecular aggregates. Matthew S. Platz was born in New York City and graduated from the State University of NY at Albany ( B.Sc. in Chemistry and Mathematics) in 1973 and obtained his Ph.D. in Chemistry studying with Professor Jerome Berson in 1976. After a postdoctoral stint with Professor Gerhard Closs, Platz joined the faculty of The Ohio State University in 1978 where he has spent his entire independent career. Platz served as chair of the OSU Chemistry Department from 1994-1999, was the Melvin S. Newman Professor (1994-2001), and was named Distinguished University Professor in 2001. Platz has been a Sloan Fellow, a Camille and Henry Dreyfus Teacher-Scholar, and a Cope Scholar of the American Chemical Society. He has over 200 scientific publications and holds over a dozen patents. Maitland Jones, Jr. turned to chemistry only after the invention of the curveball by his peers made it clear that he would never be a major league centerfielder. He received his B.S. degree from Yale College and his M. S. and Ph. D. degrees from Yale University, where he studied with William von E. Doering. After a postdoctoral year with Jerry Berson at Wisconsin he came to Princeton in 1964 as an Instructor. He has been there ever since, and is now David B. Jones Professor of Chemistry. He has been a visiting professor at Columbia and Harvard in this country, as well as at the Vrije Universiteit in Holland, the Kiev Polytechnic in Ukraine, and Fudan University in the People's Republic of China. He recently spent three months in Basel as the Freiwillige Akademische Gesellschaft Professor. He and his wife, the artist Susan Hockaday, were comasters of Stevenson Hall, one of Princeton's undergraduate colleges, for several years. Together with the members of his research group, he has published more than 200 papers centered on the chemistry of reactive intermediates, as well as a recent textbook on organic chemistry.
