Nobel Prize Recipient. Arne Tiselius, a Swedish biochemist, received international recognition after being awarded the 1948 Nobel Prize in Chemistry. He received this coveted award for, according to the Nobel Prize committee, "his research on electrophoresis and adsorption analysis, especially for his discoveries concerning the complex nature of the serum proteins." His 1930 scientific discovery later proved to be an important tool in chemical analysis. For this find, he earned his doctorate degree. He received a total of 12 nominations starting in 1940 for the Nobel candidacy, with six in the category of Chemistry and six in Physiology or Medicine. Born, Arne Wilhelm Kaurin Tiselius, the son of a mathematician, he was a young boy when his father died in 1906. At that point, his mother, with him and his sister, relocated to Gothenburg, where his interest in chemistry was inspired by a teacher. After graduation, he became an inspiring grammar school teacher of chemistry and biology. In 1921, he began to study chemistry at the University of Uppsala under 1926 Nobel Prize for Chemistry recipient Dr. Theodor Svedberg. In May of 1924 he earned his master's degree in chemistry, physics, and mathematics, becoming a research assistant in Svedberg's laboratory, studying physical chemistry. He expanded his research in ultracentrifuge. In September of 1923 he had returned to Uppsala with many new ideas after eight months at the University of Wisconsin. In 1926 he and Svedberg published an article, describing an electrophoresis apparatus using a U-tube that allowed migrating protein boundaries to be followed by ultraviolet absorption. This followed in 1930 with his doctorate degree thesis, "The Moving Boundary Method of Studying the Electrophoresis of Proteins." Upon receiving his doctorate degree, he searched for a professional position in biochemistry in Sweden without results, thus accepting a position in inorganic chemistry at Uppsala University. This led to him studying zeolite crystals, which are microporous aluminosilicate minerals found where volcanic rock and layers of ash react with alkaline groundwater. He went to Princeton University in the United States to do research with respected Professor H. S. Taylor on adsorption phenomena. He received a Rockefeller Foundation fellowship for his studies during the period of September 1934 through August 1935. It was at Princeton that he was encouraged to continue his research in electrophoresis by a host of scientists, who were familiar with his earlier work with Svedberg. He left the United States with plans for a systematic study of sources of error in electrophoresis. He was successful in his research and published an article in the "Transactions of the Faraday Society," receiving the positive support of scientists around the world. Electrophoresis is used in the 21st century in clinical chemistry laboratories today to analyze serum, urine, and cerebrospinal fluid to diagnose cancers, such as multiple myeloma, autoimmune disease, kidney disease, and hemoglobinopathies, among other applications. During World War II, his laboratory was asked to develop a means of freeze-drying plasma for military use, which was well suited for his laboratory, given the experience with proteins. From this researched, they developed Dextran, a substance to increase blood volume, which was produced commercially. Up to this point, he had worked in the laboratory alone or with one assistant, but the work had to be divided, with him overseeing the experiments. After World War II, he became very active in the Nobel Prize process being the vice president of the Nobel Foundation from 1947 to 1960 and from 1960 to 1964, the president. He became a member of the Nobel Committee for Chemistry in 1947; was chairman of the Swedish Natural Science Research Council from 1946 to 1950; and was the chairman of the Research Committee of the Swedish Cancer Society from 1951 to 1955. In 1947, he co-authored a published paper about the use of adsorption to separate insulin into its four components. He retired in 1969. He married Ingrid Margareta Dalén in 1930, and the couple had a son and a daughter. Weeks after being told to pace his activities, he died from a sudden heart attack the morning after a stressful meeting in Stockholm.
