Dr. Herbert A. Laitinen won this year's Fisher Award in Analytical Chemistry for his fundamental con tributions in electroanalytical chem istry. He presented his award ad dress March 22 before the Division of Analytical Chemistry at the 139th ACS National Meeting in St. Louis. Dr. Laitinen received his B.S. at the University of Minnesota in 1936 and his Ph.D. there in 1940. His Ph.D. thesis work on the current-time behavior of a platinum electrode in a quiet solution remains the classic proof of the validity of linear diffusion cur rent control. Since 1940, Dr. Laitinen has made many other important contributions to electroanalytical chemistry. lie was the first to use the rotating platinum microelectrodc for voltametric deter minations and amperometric titrations. tie discovered the reductibility of hy drocarbons at the dropping mercury electrode, and he made the first sys tematic study of the polarographic properties of many hydrocarbons. Another of Dr. Laitinen's research interests is the polarographv of metal ion complexes. He introduced the ap plication of the polarographic tech nique using liquid ammonia as the solvent and has evaluated the stability constants and reduction mechanisms of several metal ion complexes. Dr. Laitinen has also carried out adsorp tion studies of organic substances at the dropping mercury electrode and has studied the influence of adsorbed monolayers on the kinetics of electrode reactions, and the mechanism of the electrolytic surface oxidation of plati num and gold.
Dr. Laitinen is now a professor of analytical chemistry at the University of Illinois and also directs the univer sity's analytical chemistry division. He joined the Illinois faculty 21 years ago. In addition to an active teaching and research career, Dr. Laitinen is secretary of the Commission on Elec trochemical Data of the Analytical Section of the International Union of Pure and Applied Chemistry, a mem ber of the Advisory Panel, Bureau of Standards, Chemistry Division I, edi tor of Monographs and Special Publi cations of the Electrochemical Society, and assistant editor of Anahjtica Chimica Acta. Just last year he pub lished his first solely authored text book, "Chemical Analysis." Lately, Dr. Laitinen has been doing electrochemical research using molten lithium chloride-potassium chloride eutectic as the solvent. These studies have led to the development of av electromotive force series of more than 30 entries in this solvent. Dr. Laiti nen is continuing his work in this area using alkali metal nitrate and sulfate solvent systems. He is also studying the adsorption of organic substances at electrode surfaces and the effect of these adsorbed substances on elec trode reactions. According to one of his colleagues, "The importance of Professor Laitinen's work is its thoroughness and the manner in which he has driven to the heart of each problem that he has studied. His efforts have provided us with a much more basic under standing of electrochemical principles than we had a decade or two ago."

1961
Shortly before World War II, when the U.S. dairy industry was being plagued with a breakdown in the flavor of its milk and milk products, Dr. Vladimir N. Krukovsky, then a young assistant professor of dairy chemistry at Cornell, showed the in dustry how to store and handle fresh milk to prevent the lipolytic action behind the rancid odor and bitter taste. Precooling milk to below 10° C , warming it to 30° C , and recooling it to 10° C. was at fault, he showed. In stead, he advised, keep fresh milk be low 10° C. until pasteurization. This service to the dairy industry and his life-long studies of off-flavor s have won for Dr. Krukovsky the 1961 ACS Award in the Chemistry of Milk, sponsored by the Borden Co. Founda tion, Inc. The award will be pre sented this week at the ACS St. Louis meeting. His interest in off-flavors recently led him into studying the effect of feed and breed. So far, he has been able to establish, for instance, that cows fed orchard grass produce milk very resistant to oxidized flavors. But cows fed red clover hay or silage will give milk that is very sensitive to oxidation. When Jersey cows and Ayrshires are fed the same ration, he finds, milk from the Jerseys produces butter and frozen cream with higher flavor scores than that from Ayrshires. On the average, the milk fat from Jerseys is higher in carotenoicls and lower in io dine value than that from Ayrshires. Carotenoid value, he finds, is corre lated with tocopherol, and milk's re sistance to oxidative off-flavors de pends, at least in part, on the tocoph erol level, which is influenced by
the kind of feed the cow eats, the breed of cow, and the physiological re sponse of the individual cow to its feed. This work leads Dr. Krukovsky all over the Cornell campus—into the de partments of chemistry, animal hus bandry, animal nutrition, and home economics, as well as his more usual haunts in the department of dairy and food science. Cooperation from those departments, he says, helps make his work possible, and association with them makes it all the more interesting. Dr. Krukovsky was born in the Black Sea resort city of Odessa. He says it was "the most beautiful city in Europe" in the early 1920's, when he had to leave Russia after serving in the Anticommunist Army. By 1921, he was in Prague, attending the Poly technic Institute, from which he grad uated in agricultural chemistry. Be tween 1926 and 1929, he was assistant and then manager of agricultural in dustries in Czechoslovakia. He came to the U.S. in 1930 and in 1933, went to Cornell to work to ward his M.S. ('34) and Ph.D. ('35). He's been there ever since. Translating Russian scientific liter ature and abstracting it for Chemical Abstracts Service occupies almost all of Dr. Krukovsky's free time. But, he says, "it keeps me abreast of the field." It also makes him an informed ob server of Soviet progress in food tech nology. He says the Soviet food in dustry was considerably behind that of the U.S. for some time, but it is now picking up. He suspects that Soviet food shortages are not so much in food production as they are in storing and processing it after harvest.

ISOTOPES for Your Development Work
Fritzsche Award
CASIMIR F. SEIDEL
Oak Ridge National Laboratory offers more than 300 radioactive and stable isotope products.
RADIOISOTOPES
Dr. Casimir F. Seidel, winner of the 1961 Fritzsche Award, has been de scribed by his colleagues as "one of the most brilliant organic chemists in the field of essential oils and natural flavoring materials." Dr. Seidel will receive the award at the ACS national meeting in St. Louis. He will give his award address on Constitution and Synthesis of an Oxide from Bulgarian Rose Oil, before the Division of Or ganic Chemistry. Since 1929 Dr. Seidel has worked at the Federal Polytechnical Institute in Zurich, Switzerland, as a scientific collaborator of Firmenich & Cie., on essential oils and natural flavoring materials. Most of the work for which he is known has been done there. This includes his work on the perfume composition of ambergris, a study of macrocyclic compounds covering the musk family, an illustration of the structure of irone and its isomers, a study of the odoriferous substances in raspberry and strawberry, and the iso lation, identification, and synthesis of sclareol. His work has also covered other terpene compounds and dehydrogenation processes. Dr. Seidel's particular talent seems to be, as one of his colleagues puts it, "his ability to extract, identify, and
synthesize the elusive odoriferous sub stances which are so important to the field of essential oils and natural flavor ing materials." Dr. Seidel was born in 1895 in Hengelo in the Netherlands. He at tended college at Enschede and re ceived a bachelor's degree, then entered the Federal Polytechnical In stitute in Zurich as a student in the chemistry department. After three and a half years he got his chemical engineer's license. From September 1919 to July 1920, he worked in the research department of N.V. Stickstofbindingsindustrie "Nederland" at Dordrecht in Holland. Afterward he returned to the Federal Polytechnical Institute in Zurich where he did graduate research on the synthesis of alkaloids and terpenes under Dr. Leopold Ruzicka. In 1923, he joined Verein fur Chemische und Metallurgische Produktion at Aussig, Czechoslovakia, in the pharmaceutical laboratory; he also worked in the industrial laboratory for coloring matters. In November 1926 he became an assistant in organic chemistry to Dr. Ruzicka at the University of Utrecht, where he worked for two years.
