Life

Stegmann studied medicine at the Philipps University of Marburg and became a member of the short-lived Corps Markomannia Marburg in 1832/33. August Rühl and Hermann Wolff von Gudenberg were active with him . At the Hessian Ludwigs University , he was on 19 December 1835 for MD PhD .

On September 10, 1840, he also received his doctorate in philosophy in Marburg . After settling for higher mathematics habilitation had, he was 1840-1844 teacher of mathematics and physics at the secondary school in Marburg . Philipps University appointed him associate professor on January 23, 1845 and full professor of mathematics on August 26, 1848 . With his appointment, pure mathematics gained more weight in Marburg. In 1856 and 1862 he was Vice Rector of the University. The Philosophical Faculty elected him dean in 1857, 1861, 1864 and 1869 . 1864/65 he was interim director of the Mathematical-Physical Institute, 1869–1872 director of the scientific examination committee for candidates for the higher education authority. At the age of 71 he retired . One of his most famous students was the British physicist John Tyndall .

In his textbook on the calculus of variations he proved a weaker version of the fundamental lemma of the calculus of variations .
