	Theodor Svedberg Biography (1884-1971)
		Svedberg was raised by a civil engineer who shared his love of nature with his son.
		Svedberg wanted to identify the exact size of the colloids he studied, but this was difficult because the only way to make such measurements was to note how the particles settled through sedimentation.
		Svedberg was awarded the Nobel Prize in Chemistry in 1926 for his contributions to colloid chemistry.

	Theodor Svedberg
		Theodor 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 physicist Marian von Smoluchowski[?].
		During this work, he developed the technique of analytical ultracentrifugation[?], and demonstrated its utility in distinguishing pure proteins one from another.

	Svedberg - Wikipedia, the free encyclopedia
		A Svedberg (symbol S, sometimes Sv) is a non-SI physical unit used in ultracentrifugation.
		It is named after the Swedish physicist and chemist Theodor Svedberg (1884-1971), winner of the Nobel prize in chemistry in 1926 for his work in the chemistry of colloids and his invention of the ultracentrifuge.
		The speed is constant because the acceleration applied by the ultracentrifuge (measuring typically in the millions of gravities) is cancelled by the viscous resistance of the medium (normally water) through which the particle is moving.

	Theodor Svedberg Summary
		Svedberg used an alternating current with an induction coil whose spark gap was submerged in a liquid to produce relatively pure colloidal mixtures of metals.
		Svedberg continued his work with colloids, using an ultramicroscope (a microscope that uses refracted light for visualizing specimens too small to be seen with direct light) to study the Brownian movement of particles.
		Theodor (The) Svedberg (August 30, 1884 – February 25, 1971) was a Swedish chemist and Nobel laureate.

	The Svedberg - Biography
		Theodor (The) Svedberg was born at Fleräng, Valbo, in the county of Gävleborg, Sweden on August 30, 1884, as the son of Elias Svedberg, a works manager, and his wife, Augusta, née Alstermark.
		Svedberg accepted a post as assistant in the Chemical Institute at Uppsala in 1905 and in 1907 he was given the additional position of lecturer in chemistry in the university.
		Svedberg has contributed a large number of scientific papers to Swedish and foreign journals on colloid and high-molecular solutions, nuclear chemistry and radiation biology.

	Svedberg, Theodor H.E.,
		Svedberg's early research was on colloids, in which particles too small to be resolved by ordinary light microscopes are dispersed throughout water or some other substance.
		Svedberg found that the size and weight of the particles determined their rate of settling out, or sedimentation, and he used this fact to measure their size.
		With an ultracentrifuge, Svedberg went on to determine precisely the molecular weights of highly complex proteins such as hemoglobin.

	Svedberg, Theodor (Site not responding. Last check: 2007-10-18)
		Svedberg was born near Gävle, studied at Uppsala and spent his career there, as professor 1912-49 and head of the Institute of Nuclear Chemistry 1949-67.
		Svedberg discovered that thorium-X crystallizes with lead and barium salts (but not with others), anticipating English chemist Frederick Soddy's demonstration of the existence of isotopes.
		Svedberg also investigated, about 1923, the chemistry involved in the formation of latent images in photographic emulsions.

		Svedberg studied at the University of Uppsala and obtained his doctorate in 1907 becoming professor in 1912.
		With the exception of research periods in Göttingen and Wisconsin, Svedberg remained loyal to his Alma Mater, heading the Institute of Physical Chemistry of the University of Uppsala until retirement in 1949.
		Svedberg was chiefly interested in the chemistry of colloids and in 1923 developed the ultracentrifuge to settle the tiny colloid particles according to their molecular weights.

		The(odor) Svedberg (1884-1971) professor in physical chemistry at Uppsala University from 1912 to 1949, was awarded the Nobel Prize in chemistry in 1926 for his research on dispersed systems (colloidal solutions).
		Intensive discussions concerning the type and size of accelerators Swedish research in nuclear and high-energy physics should have at its disposal took place in early 1980's, One result of this process was that a decision was taken to bring the magnets of the so-called ICE-ring (Initial Cooling Experiment) from CERN to Uppsala.
		Since 1994 The Svedberg Laboratory is a national research facility funded to a large fraction from the Swedish Natural Science Research Council.

		Swedish chemist who won the Nobel Prize for Chemistry in 1926 for his studies in the chemistry of colloids and for his invention of the ultracentrifuge, an invaluable aid in those and subsequent studies.
		In the early 1940s, Helge Tyrén, former professor of high-energy physics, a student of 1926 Nobel Chemistry Laureate Theodor Svedberg, had constructed a neutron generator for the production of radionuclides.
		In Svedberg's discussions with the main customer of these radionuclides, gynaecology professor John Naeslund, plans emerged for a more powerful accelerator - a cyclotron - to increase the quantities of radioactive substances.
