Raymond Urgel Lemieux, CC, AOE, FRS[1] (June 16, 1920 – July 22, 2000) was a Canadian organic chemist, who pioneered a number of discoveries in the field of chemistry, his first and most famous being the synthesis of sucrose.[2] His contributions include the discovery of the anomeric effect and the development of general methodologies for the synthesis of saccharides still employed in the area of carbohydrate chemistry.[3] He was a fellow of the Royal Society of Canada and the Royal Society (England), and a recipient of the prestigious Albert Einstein World Award of Science and Wolf Prize in Chemistry.

Life and career

Dr. Raymond U. Lemieux was born in Lac La Biche, Alberta, Canada. His family moved to Edmonton, Alberta in 1926. He studied chemistry at the University of Alberta and received a BSc with Honours in Chemistry in 1943. He went on to study at McGill University, where he received his PhD in Organic Chemistry in 1946. He won a post-doctoral scholarship at Ohio State University, where Bristol Laboratories Inc. sponsored his research on the structure of streptomycin. He met his future wife, a doctoral student, at Ohio State and they were married in 1948.

In following years, he returned to Canada where he spent two years as an assistant professor at the University of Saskatchewan. Next he served as Senior Research Officer at the National Research Council's Prairie Regional Laboratory in Saskatoon. In 1953 he and a fellow researcher, George Huber, were the first scientists to successfully synthesize sucrose. In 1954, he accepted the position of Dean in the Faculty of Pure and Applied Sciences at the University of Ottawa, where he established their Department of Chemistry. In 1961 he returned to the University of Alberta as a professor in the Chemistry Department and to serve as the Chairman of the Organic Chemistry Division. He developed a method to make synthetic versions of oligosaccharides, which led to improved treatments for leukemia and hemophilia and the development of new antibiotics, blood reagents, and organ anti-rejection drugs.

While at the University of Alberta, he established a number of biochemical companies, including R&L Molecular Research Ltd. in 1962, Raylo Chemicals Ltd. in 1966 (which purchased R&L) and Chembiomed in 1977 (which has since been taken over by Synsorb Biotech of Calgary, Alberta.) Prof. Lemieux published an autobiography, entitled "Explorations with Sugars: How Sweet It Was," in 1990.[4]

Dr. Raymond Lemieux died of cancer in 2002.

In 1999, the University of Alberta Faculty of Science and Strathcona County established the Strathcona County/R.U. Lemieux Chair in Carbohydrate Chemistry. In 2001, the University of Alberta renamed the building(s) housing the Department of Chemistry to the Gunning/Lemieux Chemistry Centre to acknowledge the contributions of Profs. Raymond Lemieux and Harry Gunning.
