Svedberg, The(odor)

(born Aug. 30, 1884, Fleräng, near Gävle, Swed.—died Feb. 25, 1971, Örebro) Swedish chemist. He won a Nobel Prize in 1926 for his studies in the chemistry of colloids and for his invention of the ultracentrifuge (see centrifuge), which has become invaluable to research in biochemistry and other areas. Svedberg used it to determine precisely the molecular weights of highly complex proteins (e.g., hemoglobin). Later he made studies in nuclear chemistry, contributed to the improvement of the cyclotron, and helped his student Arne Tiselius (1902–71) develop electrophoresis.
