Theodor Svedberg

Physical chemist, born at Valbo, E Sweden. He studied at Uppsala, where he spent his whole career. In 1924 he described his ultracentrifuge, in which a solution can be spun at very high speed, generating centrifugal forces many thousand times that of gravity, and used it to develop methods for separating proteins. He was awarded the Nobel Prize for Chemistry in 1926.

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.
