After graduating in 1852 with CF Gauss in Göttingen, he worked from 1854 to 1958 as a lecturer at the University of Göttingen, from 1858 to 1862 as a professor of mathematics at the Polytechnic in Zurich and from 1862 to the end of his life as a professor of mathematics at the Technical University of Braunschweig. Dedekind created a comprehensive theory whose method was decisive for many questions of mathematics, not least for the development of modern algebra. Dedekind was a member of several academies and multiple honorary doctor. The academy in Berlin, the today's academy of the sciences of the GDR, selected him 1880 to its Corresponding member.
