    Svedberg, The (Theodor)

    (b. Fleräng, Valbo, near Gävle, Sweden, 30 August 1884; d. Örebro, Sweden, 25 February 1971)

    physical chemistry.

    Svedberg was the only child of Elias Svedberg and Augusta Alstermark. His father, a civil engineer, was a very active man with many interests besides his profession. He was strongly attracted to the study of nature and made long excursions with his son, who shared his enthusiasm. He worked as a manager of iron works in Sweden and Norway, but the family suffered economic problems from time to time. As a Gymnasium lärling Svedberg was especially interested in chemistry, physics, and biology, especially botany, and finally decided to study chemistry, believing that many unsolved problems in biology could be explained as chemical phenomena. In January 1904 he enrolled at the University of Uppsala, with which he remained associated for the rest of his life. He passed the necessary courses and examinations in record time and received the B.Sc.

    Theodor Svedberg

    Swedish chemist

    Theodor Svedberg (30 August 1884 – 25 February 1971; also known as The Svedberg) was a Swedish chemist and Nobel laureate for his research on colloids and proteins using the ultracentrifuge. Svedberg was active at Uppsala University from the mid-1900s to late 1940s. While at Uppsala, Svedberg started as a docent before becoming the university's physical chemistry head in 1912. After leaving Uppsala in 1949, Svedberg was in charge of the Gustaf Werner Institute until 1967. Apart from his 1926 Nobel Prize, Svedberg was named a Foreign Member of the Royal Society in 1944 and became part of the National Academy of Sciences in 1945.

    Early life and education

    [edit]

    Svedberg was born in Valbo, Sweden on 30 August 1884.[4] He was the son of Augusta Alstermark and Elias Svedberg. Growing up, Svedberg enjoyed botany and other branches of science.[5] While in grammar school, Svedberg conducted individual laboratorial research and

    Svedberg

    Non-SI unit for sedimentation coefficients

    For the surname, see Svedberg (surname).

    In chemistry, a Svedberg unit or svedberg (symbol S, sometimes Sv[a]) is a non-SImetric unit for sedimentation coefficients. The Svedberg unit offers a measure of a particle's size indirectly based on its sedimentation rate under acceleration (i.e. how fast a particle of given size and shape settles out of suspension).[1] The svedberg is a measure of time, defined as exactly 10−13seconds (100 fs).

    For biological macromolecules like ribosomes, the sedimentation rate is typically measured as the rate of travel in a centrifuge tube subjected to high g-force.[1]

    The svedberg (S) is distinct from the SI unit sievert or the non-SI unit sverdrup, which also use the symbol Sv, and to the SI unit Siemens which uses the symbol S too.

    Naming

    [edit]

    The unit is named after the SwedishchemistTheodor Svedberg (1884–1971), winner of the 1926 Nobel
