12 About Frank H. Westheimer Education for the 21st Century scientist

Frank Westheimer moved easily between Themes in 21st Century science , biology and computation long The Institute faculty offer tutorials on topics that are not often found before it was fashionable. By doing so, he showed how polydisciplinarity generates dis- in formal graduate programs in the sciences, but which are critical covery. Frank provides the inspiration for the for professional performance in science in the 21st century. polydisciplinary work done at the Institute. Trained at Dartmouth, Harvard, and Fund raising: Funding is the key to successful science. Institute Columbia, Frank worked at the University of trainees have their skills in this area developed in both formal and Chicago and Harvard. In his career, he devel- informal settings. oped three paradigms that today unify Intellectual property and technology transfer: In the future, chemistry and biology. pioneering scientific research will need to rely less on peer review First, Frank was an early practitioner of physical organic chemistry, which studies how chemical reactions occur. The reactions that he studied include those where mechanisms, and more on return from technology that it generates. molecules are oxidized or reduced, gain or lose phosphate, or release carbon dioxide. Institute trainees each submit a patent application which they Frank then turned to study the analogous reactions in biology. He began by prosecute pro se,to learn how this process works. seeking catalysis in amino acids, then metal ions, and then in enzymes themselves. Verbal presentation: The key to successful scientists is the ability to His work encouraged the study of enzyme mechanism, which today is key to the development of pharmaceuticals and diagnostic tools. convey scientific ideas verbally, to students, peers, and the public. Frank also introduced computation to molecular science. He founded molecular Every lecture at the Institute is recorded, so that trainees can review mechanics, and did the first computational studies of organic acids and bases. their performance with the aid of coaches. Today, molecular mechanics is key to all biological computation. Outreach: A key to successful science is contact to the public. As with those of other generalists of the last century, Frank’s contributions are so fundamental that it is difficult to believe that they were resisted when they were Institute trainees are involved in ongoing outreach activities ranging introduced. "Tierchemie ist Schmierchemie" (biochemistry is messy chemistry) was from elementary schools to the adult population, and also in activities the view of German chemists who surveyed the mixing of biology with chemistry. that measure the success of outreach using quantitative metrics. Modern society has benefited from science that is done without such blinders. Creative thinking: Much of modern training in science avoids issues Frank in 2003 asked where “our blind spots are now?” The Institute works to identify and remove these. We hope to have the same impact in the next century as basic as logic and creativity. Institute trainees are involved in both as Frank had in the last. formal and informal programs to enhance skills in both areas. Westheimer, F. H. (2003) Reflections. J. Biol.

A new organization for basic and applied research Technology developed by Institute scientists supports commercial products in many industries. The modern university as we know it may not be the most important developer of Bayer Diagnostics research and technology in the coming millennium. Its collegiate and departmental EraGen Biosciences divisions are well recognized barriers to innovation and multidisciplinarity. Its Bristol-Myers Squibb governance hinders technology transfer.
