History of mathematics and the sciences can be studied at the University of Mainz as a Minor in the B.Sc. and M.Sc. Programs of Mathematics. For details, see our Module handbook.
History of mathematics is also a component of the M.Ed. program with major in mathematics, specifically as Module 11 ("Entwicklung der Mathematik in Längs- und Quersschnitten"), and optionally as a Vertiefungsmodul.
For further details, see the M.Ed. Module handbook (and its recent amendments), that you can find on this page.
