Ilmenau is a town in Thuringia, central Germany. It is the largest town within the Ilm district with a population of 38,600, while the district capital is Arnstadt. Ilmenau is located approximately 33 km south of Erfurt and 135 km north of Nuremberg within the Ilm valley at the northern edge of the Thuringian Forest at an elevation of 500 m.
The most important institution in Ilmenau is the Technische Universität Ilmenau, a public research university and Thuringia's only "Technical University" with about 4,900 students and an emphasis on engineering disciplines, computer science, mathematics, natural sciences, economics, and media studies. Its precursor was founded in 1894 and developed into a university in 1992. Since 1990, many research institutes have been established in the vicinity making Ilmenau an important hub of technological research.
Ilmenau was historically a small mining town, primarily silver, copper and manganese, until the deposits were depleted. After 1800, it was one of Johann Wolfgang von Goethe's favourite resorts because of its beautiful surroundings. In 1838, the establishment of the town as a spa led to the advent of tourism, which is still an important industry. Industrialisation started after the railway arrived in 1879, but increased rapidly during the following century primarily in glass and porcelain manufacturing. The porcelain factories closed (as in many other places in western Europe) during the 1990s. The glass industry, however, remained and produces laboratory equipment and measurement devices and is leading source of economic activity together with mechanical, electrical, and software engineering. Ilmenau and the surrounding region have produced many winter Olympic champions in disciplines such as luge, bobsleigh, and biathlon.
