Theodor Svedberg

Theodor (The) Svedberg (August 30, 1884 –  February 25, 1971) was a Swedish chemist and Nobel laureate. His work with colloids supported the theories of Brownian motion put forward by Einstein and the Polish geophysicist Marian Smoluchowski. During this work, he developed the technique of analytical ultracentrifugation, and demonstrated its utility in distinguishing pure proteins one from another.
