Yizhak Marcus was born in Germany and immigrated to Israel as a child. He obtained his M.Sc. degree in 1952 and his Ph.D. degree in 1956 in chemistry from the Hebrew University of Jerusalem. There he was Professor of Inorganic and Analytical Chemistry from 1965 to his retirement (to emeritus status) in 1999, and he continues to be active. Professor Marcus spent a dozen years with the Israeli Atomic Energy Commission laboratories, and he was a visiting scientist and professor in various countries: Australia, England, Germany, Japan, Turkey, and the U.S.A. His research interests concern solution chemistry, and he has published in this and neighboring fields 6 books and over 270 papers in refereed journals. Glenn Hefter received his B.Sc. (in 1969) and his Ph.D. (in 1973) degrees from the University of Melbourne. He worked as a high school teacher and then at Stirling University in Scotland, the University of Malaya in Malaysia, and the Marine Science Laboratories in Australia before joining Murdoch University in 1982, where he is currently Associate Professor in Chemistry. His main research areas, in which he has published over 200 papers, are in solution chemistry, including the thermodynamics of ion solvation and the nature of ion pairs in aqueous, nonaqueous, and mixed solvents, as well as chemical speciation in complex hydrometallurgical and environmental solutions. He has had a long-standing involvement with the IUPAC-NIST Solubility Data Series and recently co-edited and contributed to a book: The Experimental Determination of Solubilities (2003).
