Joseph Ehrenfried Hofmann (* 7 March 1900 in Munich, † 7 May 1973 in Günzburg ) was a German historian of mathematics, known for his research on Gottfried Wilhelm Leibniz.

Life and Work

After graduating from high school in 1919 at the Wilhelm Gymnasium in Munich, Hofmann studied in Munich (Ph.D., 1927, Walther von Dyck and George Faber ) and was briefly an assistant in Munich and Darmstadt, before he went into the teaching profession (in Gunzburg, Nördlingen). As a student he was drawn to the history of mathematics, after Faber him for publishing the works of Euler heranzog. A big influence was Henry Wieleitner, with whom he published several works on the history of calculus. As a school teacher, he continued his historical studies. In 1939 he habilitated in the history of mathematics at the University of Berlin. 1940 to 1945 he was entrusted with the Leibniz edition of the Berlin Academy of Sciences. 1947 until his retirement in 1963 he was again high school teacher in Gunzburg. He also had (in part-time) professor of the History of Mathematics at the Albert-Ludwigs-University Freiburg, the Humboldt University of Berlin, the Eberhard Karls University of Tuebingen (honorary professorship in 1950) and the Technical University of Karlsruhe . He organized regular symposia on the history of mathematics at the Mathematical Research Institute in Oberwolfach, where he worked right after the war. Hofmann was considered an expert in the development of calculus by Leibniz, whose time in Paris he studied carefully and so significantly to the Enlightenment (or reassurance) of long in the history of mathematics echoing priority dispute between Leibniz and Isaac Newton contributed to the invention of calculus. He was co-editor of the works of Leibniz, and others of Nicholas of Cusa, Johann Bernoulli (and other reprint editions of her work in publishing and Georg Olms, Hildesheim, such as mathematics history of Abraham Gotthelf Kästner ). He also worked on number theory by Leonhard Euler and Pierre de Fermat . He discovered including some new works of Fermat (published 1943). He died after he drove off a car on the morning walk.
