March 5, 1975

Swedish physical chemist Dr. Kai Pedersen from the University of Uppsala gave the Matthew Vassar Lecture on “The Importance of the Work of The Svedberg and Arne Tiselius in the Early Development of Modern Protein Chemistry.” Dr. Pederson’s subjects were the Swedish biochemists The (Theodor) Svedberg, the early student of colloids and the developer of their study using the technique of analytical ultracentrifugation, and Arne Tisellus, Svedberg’s student and successor, especially in the electrophoresis of proteins. Svedberg received the Nobel Prize in Chemistry in 1926, and Tiselius received the Nobel Prize in Chemistry in 1938.
