Karrer, Paul

Karrer, Paul. (1889-1971). A recipient of the Nobel Prize for chemistry in 1937 with Fiaworth. Although bom in Moscow, he attended European universities and received his doctorate in Zurich. Fie initiated work on flavins, carotenoids, and vitamins A and B, and accomplished work on stmcture and synthesis of vitamin B2as well as vitamins A and E.

Karrer, Paul (1889-1971) Swiss organic chemist. Karrer was famous for his work on vitamins and vegetable pigments. In 1930 he determined the structure of carotene. In 1931 he synthesized vitamin A, having worked out the structure. Karrer was aware of the similarity between the two molecules. He subsequently determined the structures of each and synthesized riboflavin (vitamin B2) in 1937 and tocopherol (vitamin E) in 1938. Karrer shared the 1937 Nobel Prize for chemistry with Norman HAWORTH for the constitution of carotenoids, flavins, and vitamins A and B . Karrer wrote an influential textbook entitled Textbook of Organic Chemistry (1927).

HAWORTH. SIR WALTER N. 0883-1950). An English chemist who received the Nobel prize in chemistry in 1937 along with Paul Karrer. He recommended the name ascorbic acid and synthesized vitamin C, He accomplished much work on carbohydrate structure und developed a substitute for blood plasma using carbohydrates. During World War 11. he developed gaseous diffusion separation on uranium isotopes. He received his Ph D. in Manchester. England. 

While the group was in good shape from the very beginning, I had to accommodate to the imbalance between inorganic and organic chemistry in the Zurich department. In contrast to Munchen, its resources in terms of lab space and assistantships were distributed in a ratio of 1 3 in favor of the organic section. The reason was that when Alfred Werner (Fig. 2.18) retired, he was succeeded by his former student Paul Karrer (Nobel laureate 1937), who became... 

Methods, the ACS Arthur C. Cope Award, and the Paul Karrer Gold Medal. He is a Fellow of the National Academy of Science, the American Academy of Arts and Science, and the Royal Society of Chemistry. In his Nobel Lecture [163], he conceded that starting from seemingly unrelated work, our investigations into the fundamental chemistry of this transformation have been an exciting journey, with major advances often resulting from complete surprises, mistakes, and simple intuition. Ultimately, these efforts have contributed to olefin metathesis becoming the indispensable synthetic tool that it is today .

Werner received the Nobel prize in 1913, and about this time began to suffer from arteriosclerosis, but he did not become seriously ill until 1915. Then his assistants, Paul Karrer and Paul Pfeiffer, took over for him until his death on November 15, 1919. Karrer remained at the University of Zurich where his work with the vitamins has brought fame to him and...
