Hans Niels Jahnke

Hans Niels Jahnke (born July 26, 1948 in Wuppertal ) is a German math historian and math didactic .

The son of MdL Walter Jahnke was a classmate of Albrecht Dümling and Heinz Finger until he skipped a class for the first time at his school, the Obersekunda of the mathematical and scientific Carl-Duisberg-Gymnasium in Wuppertal-Oberbarmen . From 1966, Jahnke studied physics, mathematics and philosophy at the University of Tübingen and the Free University of Berlin , where he obtained his diploma in 1973. In 1979 he received his doctorate (after two years of community service) in didactics of mathematics at Bielefeld University . There he was then an academic councilor and later senior councilor. In 2000 he received his habilitation in didactics of mathematics and has been an adjunct professor there since 1995. Since 2000 he has been Professor of Mathematics Didactics at the University of Duisburg-Essen .

Jahnke dealt with the history of analysis (he is the editor of a standard work on this topic) and in particular the so-called algebraic analysis (with the central figure Leonhard Euler , in Germany the school of combinatorial analysis by Carl Friedrich Hindenburg and others), mathematics among the Romantics and application of the history of mathematics in mathematics didactics, development of the concept of numbers, evidence in mathematics lessons.

Since 1990 he has been co-editor and from 2001 to 2005 managing editor of the mathematical semester reports. From 1995 to 2001 he was the managing editor of the Journal for Mathematics Didactics. Since 2006 he has been co-editor of Historia Mathematica .
