ollowing is thefiflh set of vignettes of recipients of 1998 awards administered by the American Chemical Society. An article on the 1998 Priestley Medalist is scheduled to appear in the March 30 issue of C&EN. Most winners will receive their awards during the 215th ACS national meeting in Dallas. However, the Cope Medalist and the Cope Scholars will receive their awards at the 216th ACS national meeting in Boston, during the Arthur C Cope Symposium. The Roger Adams Award will be presented next year at the 36th National Organic Chemistry Symposium in Madison, Wis. C&EN will publish vignettes of the Cope Medalist and Cope Scholars in the next issue of C&EN.
In addition to reactions of dinitrogen molecules, other areas of research Cummins is following include new methods of inorganic synthesis, synthesis and isolation of unusually reactive transitionmetal and actinide complexes of unique design, and the development of new reagents for organic synthesis. Other accomplishments by Cummins include preparing and characterizing lowcoordinate, paramagnetic transition-metal compounds; discovering a system that deoxygenates nitric oxide; and, most recently, preparing and characterizing of one of the first transition-metal compounds having a terminally bonded phosphido ligand. Cummins is also cited by his colleagues as an excellent teacher. His lectures are described as clear and exciting. "It is clear that he has a genuine love for teaching and that he strives for excellence in the classroom as well as the reACS Award in Pure search laboratory," one colleague writes.

ucate a public woefully lacking in the understanding of science, he maintains. A native of New York City, Palca grew up on the upper west side of Manhattan. He left New York in 1970 at the age of 17 ready to see the other side of the worldCalifornia. He graduated cum laude from Pomona College in Claremont, Calif., in 1974, with a bachelor's degree in psychology. Right after graduation, he wrote to Charles Crawford, the science correspondent for WCBS in New York City, and shortly thereafter he was offered a job at WCBS as a desk assistant. Since the job didn't specifically involve covering science, however, he turned it down. Palca then returned to graduate school, receiving M.S. and Ph.D. degrees in psychology from the University of California, Santa Cruz, in 1980 and 1982, respectively. Just before Palca was to receive his Ph.D. degree, funding for researchers was tight and jobs for psychologists were scarce. He then applied and was accepted for the American Association for the Advancement of Science Mass Media Science Fellows Award and was placed at WDVMTV in Washington, D.C., to work with a science correspondent. "This was a fabulous introduction to science journalism," Palca recalls. "I was completely bitten [by the television bug]. I thought TV was the greatest thing since sliced bread." Ultimately, however, he returned to graduate school and finished his doctoral dissertation on sleep research. But once he completed his Ph.D. degree, Palca returned to science journalism and never looked back. He has worked at NBC and WDVM, has written freelance for such wide-ranging publications as Mademoiselle and Readers' Digest, and has written and produced programs for BBC Radio, CBS Radio, and PBS. Palca was the Washington news editor for Nature, a senior writer with Science magazine, and, since 1992, he has been a science correspondent for National Public Radio on programs heard every day by 10 million listeners. Palca finds almost anything of interest—a key trait for a science reporter. He is recognized for reporting on four stories with a heavy chemistry content, including a story to help people understand the stereochemistry of the DNA molecule and a story on the chemistry of champagne. For drivers stuck in traffic or just listening to the radio for fun, Palca's frequent reports on NPR's "Morning Edition," "All Things Considered," "Weekend Edition," and "Sounds Like Science" make science come alive—and the commute seem too short.

Palca
Palca recently found himself in the center of a media firestorm after breaking a story on NPR, on Jan. 7, that an obscure physicist, Richard Seed, planned to begin cloning humans. Some critics argued that Palca's report "put in play a story that soon became a case of journalistic hysteria," according to the New York Times. But Palca defends his report, saying it was properly skeptical. Palca is an avid bicyclist who bikes to work each day in Washington, D.C. His radio stories are clear and easy to understand, but "he never sacrifices accuracy for simplicity," says NPR Science Editor Anne Gudenkauf. He also has a keen sense of humor and sprinkles small jokes within discussions and his science reports. "I'm delighted by science," Palca says. "There are self-promoters in science, but more often there are a lot of interesting, really clever, and really dynamic people in science doing fascinating stuff. I was the guy who was mesmerized by organic chemistry because it's a fantastically beautiful thing these people are figuring out. A good teacher can make anything seem interesting. Something may not seem interesting on the surface—but my job is to tell you why I find it interesting. I'm having such a great time reporting about chemistry . .. and I don't have to say that 'Little Susie will have her sight restored.' "
Smith
al Arts & Sciences Jubilee Professor at the University of Illinois, Urbana-Champaign. Smith is recognized for his work in applying computer technology to chemistry education. One colleague says: "Smith is a pioneer in the effective use of technology in the teaching of chemistry at the high school and college levels. In the late 1960s, long before there was general interest in the use of computers in instruction, he took the professional risk of devoting a substantial amount of effort to computer-assisted instruction. His early work emphasized ways of using the computer to provide students with individualized instruction, specific help on wrong answers, and new ways of visualizing chemical reactions." After his first studies were initiated on the use of computer-based technology for teaching general and organic chemistry on mainframe computers in 1968, Smith extended the work to microcomputers in 1979. In 1984, he incorporated videodisc technology, which allows mixing video with computer graphics into the instructional programs. Finally, starting in 1991, he converted the analog video to digital video to optimize delivery of imageintensive instructional lessons to large numbers of students. These lessons are used at many institutions to supplement traditional instruction. In these programs, students interact with video images of experiments that are too costly or too hazardous for traditional laboratory instruction. In addition, Smith has George C.

today. I have heard, from students who have never met him, what a great teacher he is." Smith received a bachelor's degree from the University of California, Berkeley, in 1953 and a Ph.D. degree from the University of California, Los Angeles, in 1959·
James Flack Norris Award in Physical Organic Chemistry Sponsored by the ACS Northeastern Section Seminal contributions to supramolecular chemistry via self-assembly and coordination have placed PETER J. STANG on the cutting edge of contemporary physical organic chemistry, colleagues say. He is also recognized, they point out, for his previous investigations into the mechanisms of chemical reactions, especially the generation and study of novel intermediates such as vinyl cations and unsaturated carbenes. In 1969, Stang was the first chemist to prepare vinyl(enol) triflates that are now extensively used by synthetic chemists in metal-catalyzed, cross-coupling reactions. Stang, who has taught in the chemistry department at the University of Utah, Salt Lake City, for nearly 30 years, counts as one of his achievements the first preparation of a unique class of organic molecules: alkynyl carboxylate phosphate and sulfonate esters of potential biological and medicinal significance. He also singles out development of "molecular architecture" using coordination to drive and direct the self-assembly of metallocyclic polygons and polyhedra, new members of the family of supramolecular species of significance for future manufacturing of nanoscale machinery, and new materials with unique properties.

Most recently, Stang has used this meth odology for the design and self-assembly of nanoscale organoplatinum macrocy cles, the design and study of synthetic chiral nanoscopic assemblies, the mar riage of the classical covalent crown ethers and calixarenes with molecular squares, and the self-assembly of molecu lar hexagons and an octahedron with un usual T-symmetry. He is currently working on the self-assembly of cuboctahedrons and dodecahedrons. Stang was born in Nurnberg, Germa ny, raised in Hungary until he was 15, and educated in the U.S. He received a B.S. degree in chemistry, magna cum laude, from DePaul University in Chicago in 1963 and a Ph.D. degree in chemistry from the University of California, Berke ley, in 1966. Following a National Insti tutes of Health postdoctoral fellowship at Princeton University, he joined the Uni versity of Utah faculty in 1969. Today, he holds the lifetime appointment of Distin guished Professor, one of only two doz en such appointments at the university, where he also served as chemistry de partment chairman from 1989 to 1995. He is author or coauthor of more than 300 publications, including five coauthored monographs and two dozen ma jor reviews. Since 1982, Stang has been an associ ate editor of the Journal of the Ameri can Chemical Society. In 1992, he was awarded honorary doctorates from both the Russian Academy of Sciences and the Lomonosov Moscow State University. Stang was a recipient of the Alexander von Humboldt Senior Scientist Award (1977), and he has been named a Fulbright-Hays Scholar (1988), a Japan Soci ety for the Promotion of Science Fellow (1985, 1998), and a Lady Davis Visiting Professor at Technion University, Haifa, Israel (1986, 1997). 40

Alfred Bader Award in Bioinorganic or Bioorganic Chemistry
Wall, chief scientist at Research Trian gle Institute, in Research Triangle Park, N.C., studied at Rutgers University, New Brunswick, N.J., where he received B.S. (1936) and M.S. (1938) degrees in chem istry, and a Ph.D. degree in agricultural biochemistry (1939). "His enthusiasm for new ideas contin ues even today, as he continues to work on plant antitumor agents and has started a new program on the discovery of po tential antimutagenic compounds," says a colleague. Students, colleagues, and other scientists "have been inspired by his scien tific abilities and his keen managerial abil ity combined with his warm concern for others." In 1941, Wall joined the Department of Agriculture's Eastern Regional Research Laboratory. He directed a research group in the first large-scale screening of plant products for potential precursors of corti sone and other steroids. More than 7,000 plants were collected, and the group's findings led to the preparation of corti sone. In 1958, his group discovered that extract of Camptotheca acuminata had antitumor activity. Wall left USDA in I960 to start up a chemistry research group at Research Trian gle Institute (RTQ, where he continues to work. He was promoted to vice president for chemistry and life sciences in 1971. In the early years at RTI, Wall isolated and, with his colleague Mansukh C. Wani, obtained the structures of camptothecin and paclitaxel, the first two major natural products with potent antitumor activity. His group prepared more than 30 camptothecin analogs, including some with high activity against human colon cancers implanted in mice. Two pharmaceutical companies have used Wall's discovery of 10-hydroxycamptothecin to synthesi2e pharmaceuticals for ad vanced ovarian cancer and colonic cancer. Other compounds synthesized by Wall's group are in clinical trials: 9-Aminocamptothecin is in Phase Π clinical trial for treat ment of colon cancer; camptothecin is in Phase I clinical trial for breast cancer. Oth er analogs are being studied to treat chron ic lymphocytic leukemia, malaria strains, and human immunodeficiency virus. In the 1970s, Wall turned his studies of natural products to the synthesis, metabo lism, and analysis of D9-THC, the active in gredient in marijuana, and its metabolites. He developed the quantitative assay now used for detecting THC metabolites in urine. Among the many honors and awards Wall has received for his work are the
Bruce Cain Award from the American As sociation of Cancer Research, the National Cancer Institute Recognition Award, and an honorary doctorate from Uppsala Uni versity, Sweden. Wall was cliairman of ACS's North Caro lina Section (1967-68) and president of the Society for Economic Botany (1975). He is a fellow of both the American Association for the Advancement of Science and the Acade my of Pharmaceutical Sciences. Wall holds more than 50 patents that relate to precursors of steroidal hormones and synthesis of camptothecin analogs with anticancer and antiprotozoal activity.
James Bryant Conant Award in High School Chemistry Teaching Sponsored by Albemarle Corp. As the quotation of American historian Henry Brooks Adams goes, "A teacher af fects eternity; he can never tell where his influence stops." And even though she may never see where it stops, MARIA R. WALSH can certainly see that she is influ encing her students' lives. She has been selected as outstanding teacher by mem bers of the "top 10" of the Pike High School, Indianapolis, graduating classes of 1986-91 and 1993-97. For five years, Walsh was coach of the Pike Academic Competition Teams. She also developed a chemistry curriculum for those students identified as gifted and talented in science. Walsh was also selected as one of 12 exemplary chemistry teachers to partici pate in SourceView, a National Science Foundation-funded project in which high school chemistry teachers were profes sionally videotaped in their classrooms. The videotaping demonstrates two dis tinct teaching styles: One is teachercentered and consists of lectures and notetaking and watching videos and demon strations; the other is student-directed, with students actively involved in discus sion, experiments, and discovery. Walsh's style is student-centered and, as the video demonstrates, this method raises the level of student interest. Walsh says: "Science is a verb. In my classroom, my goals are that my students learn chemistry in an atmosphere relative ly free of anxiety, that students assume re sponsibility for their learning, that I devel op the means for them to accomplish this, that they learn skills that can be applied to any life experience, and that I be a posi
tive influence in their personal growth." The enrollment in chemistry classes at Pike High School has increased more than four fold during Walsh's 17 years there. With the addition of the American Chemical Society's ChemCom curriculum three years ago, 71% of the class of 1996 had complet ed a year of chemistry by graduation. Examples of the high praise Walsh con sistently receives in student evaluations in clude the comments: "enthusiastic and outstanding teacher," "she is outstanding in that she 'teaches' the material instead of just presenting it," and "the thing I liked about the instructor is that she thoroughly enjoys teaching and is a great help when one is having trouble." Walsh's involvement extends beyond the doors of Pike High School. She is ac tively involved in ACS's Project SEED pro gram, and she has sponsored students for the National Institutes of Health Research Apprenticeship Program for Minority High School Students at Indiana University Med ical School and for the National Science Fair sponsored by the National Organiza tion for the Professional Advancement of Black Chemists & Chemical Engineers. Walsh also has served in a leadership role in the Indiana Local Section as chairelect (1992) and chair (1993) as well as serving as president of the Indiana Alliance of Chemistry Teachers in 1991. She has been instrumental in promoting the influ ence of the local section on local schools and in enhancing the professional devel opment of other teachers. One teacher says, "Walsh truly inspired me with her enthusiasm, commitment to science edu cation, and innovativeness." Among her major awards are the 1994 Tandy Prize for Excellence in Mathemat ics, Science & Computer Science; the 1994 ACS Regional Award for High School Chemistry Teaching; and the 1995 Presi dential Award for Excellence in Science & Mathematics Teaching. She has presented more than 35 papers and workshops both nationally and internationally. Walsh received a B.A. degree in chemis try in I960fromHunter College, New York City, and an MA. degree in organic chemis tryfromColumbia University in 1961.
ACS Award in Polymer Chemistry Sponsored by Mobil Chemical Co. GERHARD WEGNER, director of the Max Planck Institute for Polymer Research in Mainz, Germany, and a professor at the FEBRUARY 16, 1998 C&EN 41
awards University of Mainz's Institute of Physical Chemistry, "has probably done more than any single person in advancing the state of polymer research," according to one colleague. His scientific work has ranged from innovative polymer synthesis and solid-state chemistry through new concepts for structural and functional polymer materials to the study of structure-property relationships in macromolecular and supramolecular systems. Wegner started his independent scientific investigations in 1969 with the discovery and elucidation of the photochemical polymerization of macroscopic crystals of diacetylene compounds in the solid state to form a new family of conjugated polymers, the polydiacetylenes. He subsequently extended his interests to other solid-state topochemically driven polymerizations including those of tetroxane, trioxane, and oxetanes. Since the early 1980s, Wegner has made seminal contributions to the study of organic metals, including polyacetylenes, polyphenylenes, and polyphenylenevinylenes. He has also synthesized polyethylene lamellar crystals and developed new methods for assembling supramolecular architectures, specifically polymers with flexible side chains known as "hairy rods." His current interests include the application of the Langmuir-Blodgett technique to rodlike macromolecules, the use of polymers as semiconductors and dielectrics, the optical and nonlinear optical properties of polymers, polymer surfaces and interfaces, molecular recognition, and the computer modeling of polymer structures and molecular interactions of polymers. Wegner, who received a Ph.D. degree and Habilitation from the University of Mainz in 1965 and 1970, respectively, was a professor at that university's Institute of Physical Chemistry from 1971 to 1974. For the next 10 years, he was professor and director of the Institute of Macromolecular Chemistry, University of Freiburg, Germany. Since 1984, Wegner has been director of the Max Planck Institute for Polymer Research—an institute that he cofounded with Erhard W. Fischer—and, at the same time, professor again at the Institute of Physical Chemistry. He is also vice president of the Max Planck Society. His research in polymer science and organic solid-state chemistry is documented in more than 400 publications. He has been guest professor and named lecturer at universities throughout the world and has received several major awards for his achievements in polymer research. 42
