The University of Hohenheim (German: Universität Hohenheim) is a university in Stuttgart, Germany. Founded in 1818 it is Stuttgart's oldest university and one of Germany's leading universities both in agricultural sciences and economics. From 1770 to 1794, the Karlsschule was the only university in Stuttgart. Since 1818, Stuttgart's oldest university is the University of Hohenheim. It is not related to the University of Stuttgart (founded in 1829), apart from some cooperations. On November 20, 1818, Hohenheim became the site of an important agricultural institution, founded by King William I of Württemberg for teaching, experimentation and demonstration. The first director was Johann Nepomuk Schwerz, and it was located in Hohenheim Castle built by Duke Karl Eugen. In 1847 the institution was designated as holding the rank of an "Academy of Agriculture and Forestry". In 1904 the name was changed to "Agricultural College". Hohenheim College was awarded the right to confer doctorates in 1918 and habilitations in 1919. By appointing Margarete von Wrangell on the chair for plant nutrition in 1923, she became the first female full professor at a German university.
