Jesper Lützen (born 8 October 1951 in Svendborg) is a Danish historian of mathematics and the physical sciences.
Lützen graduated in mathematics (with a minor in physics) in 1976 from Aarhus University, where he also earned his PhD in 1980 in the history of science under the supervision of Kirsti Andersen.
Lützen's research deals with the prehistory of distributions (before their precisely-defined introduction by Sergei Sobolev around 1936 and Laurent Schwartz around 1950), as well as Joseph Liouville (whose biography he wrote) and Heinrich Hertz and Hertz's mechanics.
[1] He is a co-editor of the Archive for History of Exact Sciences, Historia Mathematica, and the Revue d'histoire des mathématiques, as well as Springer Verlag's book series Archimedes: New Sources and Studies in the History of Mathematics and Physical Sciences with series editor Jed Buchwald.
He was elected in 1996 a member of the Royal Danish Academy of Sciences and Letters and in 2012 a Fellow of the American Mathematical Society.
