Dr. W. 0. Baker Receives Perkin Medal The man who directs the research of one of the world's largest and most productive industrial laboratories is the winner of the Perkin Medal for 1963. He is Dr. William O. Baker, vice president for research of Bell Telephone Laboratories. The Perkin Medal, sponsored by the American Section of the Society of Chemical Industry, commemorates the work of Sir William Henry Perkin, the chemist who synthesized mauve dye and laid the groundwork for the coal chemicals industry. Dr. Baker is the 57th recipient of the medal, one of the top awards in American chemistry. He received the medal last week at a dinner at the Waldorf-Astoria Hotel in New York City. As Bell Laboratories' vice president for research (since 1955), Dr. Baker leads a technical staff of about 1200, located primarily at Murray Hill, N.J. Other laboratories are at Whippany, N.J., Holmdel, N.J., and New York City. The laboratories' patent division also reports to Dr. Baker. The Perkin Medalist was born in Chestertown, Md., in 1915. His formal schooling began in a one-room, one-teacher, Quaker country school in Maryland. It ended with a Ph.D. in physical chemistry from Princeton University, where he held the Harvard and Proctor Fellowships. He received the B.S. from Washington College in Chestertown in 1935. He did his doctoral thesis research with Prof. Charles P. Smyth. It was at Princeton that the medalist began his studies on the relation of dielectric behavior to molecular structure. Seven papers stemmed from his doctoral thesis research. Prof. Smyth has said, "The considerable number of our joint papers was due largely to Bill's energy and originality." His work at Princeton was an early stage of what came to be solid state research. In this work he determined the dielectric constant and absorption for several polyatomic dipolar organic compounds. These findings clearly indicated that the degree of molecular rotation (extending into the solid state well below the melting point) affected the entropy of fusion. Later, at Bell Telephone Laboratories, Dr. Baker studied the relation of dielectric prop90

Dr. W. O. Baker From a one-room school erties to the structure of certain crystalline polymers. He found that these properties, and even the melting points of technically important polyesters and polyamides, are determined by the orientation and concentration of the molecules' polar groups. The properties are modified to some extent by the polar groups' neighbors. After receiving the Ph.D., in 1938, Dr. Baker began research in physical chemistry at Bell Telephone Laboratories in 1939. Much of his research has been on the study of macromolecules, the giant molecules that are the basic elements of plastics, fibers, natural and synthetic rubbers, and of the tissue of growing plants and animals. These studies, many in collaboration with Dr. C. S. Fuller, Dr. W. P. xMason, and others, were made principally on a number of new polymers. A variety of experimental methods and techniques were used. Helical structures were discovered for certain synthetic polyamides, yielding simple analogies to protein and nucleic acid structures. Dr. Baker's studies on macromolecules provided a basis for solving the polyethylene cracking problem. This problem was encountered in polyethylene's early use in sheathing large telephone cables. His studies showed that polyethylene and some other polymers that elongate readily under uniaxial stress may crack when subjected to biaxial stress. Sorbed liquids greatly increase the cracking. He found that polyethylene's tendency to
crack under complex stressing depends mainly on the low molecular weight component. Thus the problem was solved by requiring better manufacturing control and eliminating very low molecular weight material. A most notable contribution to polymer science was Dr. Baker's concept of "microgel." This concept was extremely valuable in controlling the quality of synthetic rubber in the Government's wartime rubber program. The microgel concept, generally useful for all polymers, is expressed as follows: Synthetic rubber's gel fraction arises from a characteristic structure in the raw rubber that affects the final vulcanizate's physical properties and quality. Accessibility and concentration of catalyst, modifiers, and the supplied monomers govern this supermolecular cross-linked molecular unit, microgel. The emulsion medium permits truly three-dimensional or globular synthetic molecules to be made. Their average molecular weights (hundreds of millions to billions) posed a measurement problem solved by Prof. Peter Debye's modern light scattering methods. This microgel concept led to Dr. Baker's interest in highly netted polymers. With Dr. F. H. Winslow he found that, instead of vaporizing by cracking, many netted polymers would dehydrogenate to yield denser networks. This resulted in the proposal to use cross-linked polymers as ablative heat shields for protecting missiles and satellites from burning up upon re-entry into the atmosphere. Such polymer shields are now in use. For many years Dr. Baker has served in consulting and advisory capacities in Washington. Currently, he is a member of the National Science Board and a consultant in the Executive Office of the President (Office of Science and Technology) and the Department of Defense. He has served as councilor, and on national committees of the ACS. He is a fellow of the American Physical Society and a member of the National Academy of Sciences. Dr. Baker was married in 1941 and has one son. According to a colleague and personal acquaintance, "He is as remarkable as his work. He is widely read in literature and history as well as in science. He can recall and describe the significant findings in the sciences, and he remembers and can call by name almost everyone he has ever met."

NUCLEAR ROCKETRY The Los Alamos Scientific Laboratory has openings for scientific and engineering personnel in Project Rover (nuclear reactors for rocket propulsion). At Los Alamos, New Mexico, located high in the pine-covered mountains of northern New Mexico, a small nucleus of scientists and engineers is creating the modern technology and basic research to make nuclear reactors practical for space propulsion. These reactors generate many thousands of thermal kilowatts per cubic foot of core, yet start-up time is measured in tens of seconds. Precise sensing of reactor system conditions and fast response command of power and propellant flow are requirements which challenge the best of current reactor and rocket engine technology. In an atmosphere of inquiry and imaginative applied research, individuals are pooling their diverse skills and challenging their competence to solve the expected and unexpected problems posed by nuclear rocketry. At the National Nuclear Rocket Development Station near Las Vegas, Nevada, the most powerful reactors ever built are being tested and analyzed by the Los Alamos Scientific Laboratory.

Dr. Mildred Cohn
The interdisciplinary approach to solv ing problems has been growing in popularity in the scientific community during the past 10 years. But long before that, in the late 1930's, Dr. Mildred Cohn, the Garvan Medalist for 1963, began to practice the inter disciplinary art. Dr. Cohn is with the Johnson Foun dation of the University of Pennsyl vania, Philadelphia. She received the award during the ACS national meet ing in Cincinnati. The medalist is a pioneer in the use of the oxygen isotope, 0 1 S , to study enzymic mechanisms, especially with re spect to bond cleavage. In particular, Dr. Cohn used the oxygen isotope to study the cleavage reactions in such substances as glucose-1-phosphate, adenosine diphosphate (ADP), and adenosine triphosphate (ATP). She also used the technique to learn about the phosphorus-water exchange that is catalyzed by mitochondria concomi tant with oxidative phosphorylation. In addition, she has studied the nu clear magnetic resonance spectra of ADP and ATP and their complexes with divalent metal ions. This widely based and varied scien tific experience did not originate de novo. It started when Dr. Cohn, who had a B.A. (1931) from New York's Hunter College, took her advanced training with Dr. Harold Urey at Co lumbia University. There, in 1938, she received a Ph.D. in physical chem istry. Her dissertation was on the use of 0 1 S to study exchange reactions of organic compounds. From Dr. Urey's laboratory, Dr. Cohn went to work with Dr. Vincent du Vigneaud at Cornell University medical college, New York City. At
Cornell for eight years, she played a significant role in the introduction of the heavy isotopes of nitrogen and hy drogen into the study of biological problems. In 1946 Dr. Cohn moved to Wash ington University medical school, St. Louis, Mo. There she worked until 1950 with the biochemical husbandand-wife team, Carl and Gerti Cori. In St. Louis Dr. Cohn began the studies that helped eventually to open the door to the mechanism of oxida tive phosphorylation, other phosphate transfer reactions, and the mode of ac tion of uncouplers such as dinitrophenol. From St. Louis, Dr. Cohn went to Harvard medical school, Boston, Mass. (1950-51), where she worked with Dr. B. A. Hastings. In 1951 she went back to Washington University where she remained until 1960. For eight months, in 1955, she worked in England with Prof. H. A. Krebs. While at St. Louis, Dr. Cohn was appointed Established Investigator of the American Heart Association. When she joined the Johnson Foun dation in 1960, she became associate professor of biophysics and physical biochemistry, becoming a full profes sor a year later. Dr. Cohn is married to Dr. Henry Primakoff, Donner Professor of Phys ics at the University of Pennsylvania, Philadelphia. They met during a physics course that they were taking together when they were students at Columbia. They married in 1938 and have three children: a 20-year-old daughter who is a psychology major at Stanford, an 18-year-old son who is studying biochemical science at Har vard, and a 13-year-old daughter.
