Dr. Mark took his doctorate from the University of Vienna in 1921, and worked at the Kaiser Wilhelm Institute, IG Farben, the University of Vienna, and the Canadian International Paper Co. before going to Brooklyn Poly in 1940. He is editor of the Journal of Polymer Science and the Journal of Applied Polymer Science.

Nichols Medal to Mark Given enough rope, some men have been known to hang themselves. For Dr. Herman F. Mark, in 1923 a young chemist at the Kaiser Wilhelm Institute in Germany, a bit of rope helped to launch a career, if not a whole branch of chemistry. With a small piece of hemp, Dr. Mark showed that cellulose is made up of macromolecules, a startling concept at the time. On March 11, Dr. Mark got the William H. Nichols Medal of the ACS New York Section. The subject of Dr. Mark's talk at the award presentation was Polymers, Past and Future. And he is without doubt qualified to expound on this topic: That Dr. Mark has had a heavy hand in almost all aspects of polymers, past, is a fact of chemical history; that Dr. Mark will have a good bit to do with polymers, future, is one of the safest bets anyone could make. As director of the Polymer Research Institute at Brooklyn Poly, Dr. Mark oversees seven professors and eight graduate students who are setting down the theoretical groundwork that will help to make future polymers better. As consultant to industry, Dr. Mark adds his 35 years of polymer experience to that of those seeking to solve application problems. And as professor of organic chemistry at Brooklyn Poly, he guides the development of some of tomorrow's polymer experts. 102

What polymer science owes to Dr. Mark was summed up some years ago by British chemist, Sir Eric Rideal, writing in the Journal of Polymer Science: "There are no workers in the world in this field who at some point in their investigations are not indebted to his pioneering work." With the Nichols Medal, Dr. Mark was cited in particular for research conducted and reported during the past five years. This includes the synthesis of several new monomers, vinyl and acrylic derivatives, as well as studies on the mechanics of polymerization. One of his interests is solid state polymerization. Powdered acrylamide, for instance, can be polymerized in the solid state, and retains some crystalline features that are lost if the monomer is in liquid form. Solid state polymerization of olefins is theoretically possible, Dr. Mark says, and might result in improved polymers. In the future, Mark's Polymer Research Institute will be concentrating on three general areas: photopolymerization, high-speed polymerization and ways to make polymers with higher regularity. On high-speed reactions Dr. Mark says: "We now take in the order of a half-hour for a polymerization. But why not do the same job in say one-half second?" Dr. Mark thinks this might be possible with the use of new catalysts and very high purity monomers.

Hillebrand Award to Heppel Earlier this month, Dr. Leon A. Heppel broke away from his laboratory (where he works up to 14 hours a day, seven days a week) at the Na-
tional Institutes of Health to attend a dinner meeting where he received the 1959 Hillebrand Award of the Chemical Society of Washington. The fifth NIH scientist to get the award, Dr. Heppel was honored for discovering and isolating several specific ribonucleases and phosphodiesterases and using them to clarify the structure and metabolism of ribonucleic acid (RNA). He was also cited for his research on the enzyme polynucleotide phosphorylase ( P N P ) , and how it plays a part in the biosynthesis of nucleic acid. Dr. Heppel believes more work is required in discovering and evaluating new hydrolytic enzymes and in developing techniques for the complete separation of both nucleic acids and larger nucleic acid fragments. He is now working with NIH's Dr. Herbert Sober on the separation of polynucleotides with chain length greater than six. At present, Dr. Heppel is making an extensive survey of the inhibition of polymerization reactions catalyzed by PNP, following up an initial observation of Dr. Severo Ochoa (who shared the 1959 Nobel Prize in Medicine with Dr. Arthur Kornberg). One of his initial observations is that polymerization of a given nucleoside diphosphate is inhibited only by a
104

homopolymer whose base can combine with the base represented by the nucleoside diphosphate by hydrogen bonding. For example, polyadenylic acid specifically inhibits the polymerization of the diphosphates of uridine, inosine, and thymine ribonucleoside. This, says Dr. Heppel, correlates with the fact established by Warner, Rich, Felsenfeld, and others that polyadenylic acid can form hydrogen-bonded structures with homopolymers containing uridine, inosine, and thymine ribonucleoside. Recently, NIH's Dr. Marie Lipsett, collaborating with NIH's Dr. Dan Bradley and Dr. Heppel, has also observed that adenine oligonucleotides (small polynucleotides) will form completely hydrogen-bonded structures with polyuridylic acids. This new knowledge about hydrogen bonding should lead to better understanding of RNA. Although Dr. Heppel is chief of the laboratory of biochemistry and metabolism, National Institute of Arthritis and Metabolic Diseases, and has his share of administrative duties, he continues to make the lab bench the center of his life. He picked up this habit some 17 years ago when he and Dr. Kornberg worked together as bachelors. However, he finds time for his wife, Adelaide, and their two children. He is an editor of the Journal of Biological Chemistry. He received his Ph.D. in biochemistry from the University of California in 1937 and his M.D. at the University of Rochester in 1941. He went to NIH in 1942 and did research on the toxicity of halogenated hydrocarbons until 1947, when he began to study their enzymatic reactions. During 1953, Dr. Heppel worked in the laboratory of Dr. Roy Markham at Cambridge University. There he used the chromatographic techniques developed in Dr. Markham's lab for isolating and identifying nucleotides. Dr. Heppel feels that much progress has been made by combining medical and chemical know-how. He points out that at NIH's biochemistry and metabolism laboratory, many young M.D.'s have spent several years as research associates, thus getting an expert knowledge of biochemistry and the opportunity to do basic research.

And your product? Will it, too, take its place in a few seasons among these bits of nostalgia? Why not? Foster D. Snell, Inc., has built a business in preparing today's products to meet tomorrow's competition. Sometimes all that's needed is a new package, as in the development of the non-rigid vacuum packs for cheeses, bacon, and cold cuts; it may be a change in the way your product looks, smells, performs, as in the case of a new pine-scented, foaming, household ammonia. On the other hand, we are often asked to translate a blue-sky product-idea into a hard, salable reality, as in the case of latex emulsion paints, or the "pushbutton" shave-lather, or to develop new uses for a raw material as old as civilization, as in the case of our sucrose-ester detergents. Why Snell? Good question. Some of our clients have chosen us for our 40 years of professional experience; some for our million-dollar facilities; some for our experienced staff of 124; some for the fact that Snell services require no fixed overhead; you pay for what you use, not a penny more! Half of our projects are billed out at less than $1,000. Best reason of a l l . . . . but why don't you get in touch with us and find your own reason to use Snell services? FREE BOOKLETS

This great seaborne health center will carry a new kind of aid abroad—with your help. Part of the v people-to-people project Hope, it will enlist 200 specialists in sharing our health skills. OFFICIAL UNITED STATES NAVY PHOT0ORAPH
Ambassador with a blackboard, the Hope specialist will help the often woefully few local medical technicians train helpers. The result: many more hands. And that means one Hope dollar is multiplied many times over.
YOUR HELP CAN COME BACK A HUNDRED TIMES OVER If enough of us help, the S.S. Hope will be outbound in 1960. First port of call: Indonesia. A bold health project called Hope will be underway. The need is crucial. Many places, too many health hazards exist. Too many people robbed of the will to live. Too few hands to help. Often, a doctor for 100,000. Hope's approach is practical. Help where a nation's doctors ask help. Help them help themselves to health. By training, upgrade skills—multiply hands. Hope's doctors, dentists, nurses, and technicians will man a center complete to 300-bed mobile unit and portable TV. You can not only make every dollar do the work of many, you can earn a priceless dividend. With health comes self-respect. People at peace with themselves are less likely to war with others. Hope is yours to give. It's a people-to-people project. For one year's worth, 3Vi million Americans must give a dollar. Don't wait to be asked. Mail a dollar or more now to HOPE, Box 9808, Washington 15, D.C.
One local doctor for 100,000 people. These are the odds Hope may face. Yet Hope can mean so much. The health of this child. The health of five Indonesians. Trained hands and only a dol- # lar's worth of penicillin can cure them of crippling yaws. •i'^^* *fc et**
