AWARDS

Alexander Rich to receive 1995 Pauling Award Alexander Rich, professor of biophys­ ics at Massachusetts Institute of Tech­ nology, will accept the 1995 Linus Pauling Award of the ACS Puget Sound, Oregon, and Portland Sections. The award, which consists of a gold medal, recognizes outstanding achieve­ ment in chemistry. Rich's undergraduate studies at Harvard Uni­ versity centered on phys­ ics, chemistry, and bio­ chemical sciences. He re­ ceived an M.D. degree at Harvard Medical School in 1949, and joined the chemistry department at California Institute of Technology to do post­ doctoral work with Li­ nus Pauling. While at Caltech, he initiated Xray diffraction studies on 124

both small molecules and polymeric nu­ cleic acids. From 1954 to 1958 he was head of the section on physical chemis­ try at the National Institutes of Health in Bethesda, Md., and was a visiting scien­ tist at the Cavendish Laboratory in Cam­ bridge, England, in 1955, working with various colleagues. Rich discovered the three-dimensional struc­ ture of collagen. He also discovered the first hy­ bridization reaction in which two unstructured polynucleotides combine to form a double helix. This reaction became one of the major analytical tools in the development of molecular biology. It also demonstrated that the RNA molecule, like DNA, could exist as a

stable double helix. A year later, he dis­ covered the nucleic acid triple helix. In 1958, Rich moved to the biology de­ partment at MIT, where he is now Sedgewick Professor of Biophysics. One of his major accomplishments at MIT is formation of a hybrid helix containing a DNA strand and an RNA strand. He discovered and characterized polyribosomal structures involved in protein synthesis and also discovered DNA in chloroplasts. Rich's group was the first to obtain high-resolution crystals of transfer RNA. He then proceeded to find its three-dimensional folding and to un­ cover the fine details of its molecular structure. Further work in this field led to the discovery of a left-handed form of the DNA double helix. Rich is the author of 500 publications, and has received many honors and awards, including a 1995 National Med­ al of Science. The Pauling Award Sym­ posium will be held Saturday, Oct. 28, at 1:30 PM in Willamette Hall, Room 100,
