The Svedberg
The (Theodor) Svedberg ( pronunciation : [ ˌteː ˈsveːdbæɹʝ ], born August 30, 1884 in Valbo , Gävle municipality , † February 26, 1971 in Kopparberg ) was a Swedish chemist and 1926 Nobel Prize winner.
life and work
Svedberg began his studies at Uppsala University in 1904 . In 1905 he passed the examination to become a candidate for philosophy . The Filosofie licentiat followed in 1907 and the Filosofie doctor in 1908 . As early as 1907, Svedberg worked as a lecturer in chemistry at the university. From 1908 to 1912 he gave lectures in physical chemistry . In this department he was appointed professor in 1912. In 1913 Svedberg became a member of the Royal Swedish Academy of Sciences .
He mainly carried out research on colloids (solutions of finely divided macromolecules , e.g. of proteins in water). To do this, he constructed analytical ultracentrifuges with which, among other things, he could determine the molecular mass of proteins. Svedberg received the Nobel Prize in Chemistry in 1926 for his work on disperse systems . He determined u. a. the sedimentation coefficients of the respiratory blood proteins of nereis ( hemoglobin ) and octopus ( hemocyanin ).
According to him, the unit of measurement for the sedimentation coefficient is the Svedberg unit S , which indicates the speed with which large molecules or small particles are deposited in the unit acceleration field of an ultracentrifuge.
The Svedberg was married to the doctor Andrea Andreen between 1909 and 1915 . The marriage resulted in two children, the architects Hillevi Svedberg and Elias Svedberg.
Honors and memberships
The moon crater Svedberg is named after him. The Institute of Physics at Stockholm University has also named a lecture hall after him.
In 1925 he was elected a corresponding member of the Göttingen Academy of Sciences . In 1944 Svedberg was admitted to the Royal Society as a Foreign Member . In 1945 he was elected to the National Academy of Sciences , in 1948 to the American Academy of Arts and Sciences . Svedberg was a member of the German Academy of Sciences Leopoldina and since 1966 a foreign member of the then Academy of Sciences of the USSR .
