Hans Wussing
Hans-Ludwig Wußing (October 15, 1927 in Waldheim – April 26, 2011 in Leipzig) was a German historian of mathematics and science. Life. Wussing graduated from high school, and from 1947 to 52 studied mathematics and physics at the University of Leipzig. Ernst Hölder was one of his teachers. In 1952 he took the state examination, and received his doctorate in 1957. His dissertation was on embedding finite groups. From 1956 to 1966 he was assistant at the Karl-Sudhoff Institute for the History of Medicine and Science at the University of Leipzig. He qualified as a professor there  in 1966 with a ground-breaking work on the genesis of the abstract group concept. From 1966 to 1968 Wußing was lecturer, and from 1968 professor, of history of mathematics and natural sciences. In 1969 his book "Genesis of the Abstract Group Concept" was published in German; it was translated by Abe Shenitzer and Hardy Grant in 1984. B.H. Newman wrote in Mathematical Reviews (see external link below) that Wussing's "main thesis, ably defended and well documented, is that the roots of the abstract notion of a group do not lie, as frequently assumed, only in the theory of  algebraic equations, but they are also to be found in the geometry and in the theory of numbers at the end of the 18th and the first half of the 19th centuries". Newman comments that Wussings bibliography is "oddly arranged". Newman also notes that a broader perspective on the topic would require reading the works of George Abram Miller. Promoted from a department head at the Karl-Sudhoff Institute, he headed the institute from 1977 to 1982. In 1971 he became a corresponding member of the International Academy of the History of Science, and a regular member in 1981. In  1984 he became a full member of the Saxon Academy of Sciences in Leipzig. Wussing retired in 1992. Wussing is the author of numerous scientific historical publications, the author of many mathematicians' biographies, and co-editor of several series of publications, including biographies in the Teubner Verlag, and several volumes in the series "Klassiker der exakten Wissenschaften" (Ostwald's Classics of the Exact Sciences), in particular on Euler's work on functional theory, Gauss' diary, and Felix Klein's Erlangen program. In 1993 he was awarded the Kenneth O. May Prize. Until 1998 he was Chairman of the Commission for  the History of Science at the Saxon Academy of Sciences. He was also involved in the publication of Johann Christian Poggendorff's "Biographical and Literary Pocket Dictionary of the History of Exact Sciences.
