Award Statement C&EN (Page 1) Since 1981, Armbruster and coworkers at GSI and other European institutes have created six new elements—elements 107 to 112—by bombarding bismuth or lead targets with high-energy beams of metal atoms. Last February, the multinational team synthesized one atom of element 112—the newest and heaviest of all elements—by fusing lead and zinc atoms. One of the […]

Award Statement C&EN (Page 4) Born in Madison, Wis., Ehmann received a B.S. in 1952 and an M.S. in 1954, both in chemistry from the University of Wisconsin, Madison, and a Ph.D. in radiochemistry from Carnegie Institute of Technology (now Carnegie Mellon University) in 1957. After completing a postdoctoral fellowship at Argonne National Laboratory, he joined the University of Kentucky […]
Award Statement C&EN (Page 4) Natowitz received a Ph.D. degree in nuclear chemistry at the University of Pittsburgh in 1965. Natowitz and his collaborators have made a number of seminal contributions to the understanding of heavy-ioninduced nuclear reactions. They have spearheaded the study of light particle emission to provide important experimental tests of the predicted thermodynamic properties of nuclei at […]
Award Statement C&EN (Pages 2-3) Hulet received a B.S. degree in chemistry from Stanford University in 1949 and a Ph.D. degree in nuclear chemistry from the University of California, Berkeley, in 1953. His work as leader of the heavy elements group at Lawrence Livermore National Laboratory from 1966 until his retirement in 1991 enabled him to accomplish “firsts” in nuclear […]
Award Statement C&EN (Page 5) Diamond received his B.S. from UCLA in 1947 and his Ph.D. degree from the University of California, Berkeley, in 1951. Diamond’s early career focused on the development of cation exchange methods for separation of transplutonium elements. From 1950 until 1965, his research involved experiments and theory explaining ion-exchange resin and solvent extraction behavior. After joining […]
Award Statement C&EN (Page 1) Born in Hamilton, Ontario, Canada, Clayton attended Queen’s University in Kingston, where he received B.S. and M.S. degrees in 1951 and 1952, respectively. In 1955 he obtained a Ph.D. degree at California Institute of Technology. In 1973, he discovered oxygen isotope anomalies in meteorites, which has provided striking new insights into the nuclear and chemical […]
Award Statement C&EN (Pages 1-2) Alexander obtained a B.S. degree in math and chemistry from Davidson College, in North Carolina, in 1953 and a Ph.D. degree in physical and nuclear chemistry from Massachusetts Institute of Technology in 1956. Along with his research colleagues, he was one of the early investigators of heavy-ion nuclear reactions. He helped provide the first extensive […]
Award Statement C&EN (Pages 4-5) Michael J. Welch was a pioneer in radiopharmaceutical chemistry and professor of radiology, chemistry, developmental biology, and biomedical engineering at Washington University in St. Louis. Born in Stoke-on-Trent, England, Welch earned a B.A. in 1961 and an M.A. in 1964, both in natural sciences, from Cambridge University. He received a Ph.D. in chemistry from the […]
Award Statement C&EN (Pages 2-3) Macfarlane received a B.S. from the University of Buffalo in 1954, and M.S. (1957) and Ph.D. (1959) degrees from Carnegie Institute of Technology. Macfarlane along with fellow postdoc Roger Griffioen discovered a new method for the analysis of short-lived radioactive species—the helium jet recoil transport method—which Macfarlane and his coworkers have used, over the years, […]
Award Statement C&EN (page 2-3) Herrmann received his diploma degree in 1954 and his doctoral degree under the direction of Fritz Strassmann in 1956 from Johannes Gutenberg-Universität. He was instrumental in establishing the university’s research reactor that went into operation in 1967. The 61-year-old chemist has had a prolific research output, mainly in five interrelated areas: development of rapid, automated […]
