a college preparation institute (Arbeiter-und-Bauern-Fakultät (ABF) „Wilhelm Pieck“). Since 1990 In the aftermath of German reunification, the infrastructure and academic body were reorganized in order to fit the new political circumstances. After its incorporation into the West German system of higher education, Bergakademie quickly found a prime position as "The University of Resources". As the first East German University, it joined the German Research Foundation. In connection, the social sciences section were eliminated, while a faculty for economics was restructured and expanded to 15 professorships. One of the emerging focus points in research was semiconductors, which led to corporations settling in and around Freiberg. These include Siltronic AG, Meyer Burger Technology AG, and JT Energy Systems, specializing in semiconductors, solar power, and lithium-ion batteries, respectively. Besides geo- and materials sciences, environmental science became a university strong point. In March 1993, then Technische Hochschule Bergakademie Freiberg was renamed Technische Universität Bergakademie Freiberg, underlining its increased status and significance. Today, TUBAF is a modern & environmentally focused university, internationally recognized as a "university of closed resource cycles". The university's history is presented in the Historicum through numerous exhibits, paintings and photographs, and documents. The Forum for Mining History (Forum Montangeschichte) is responsible for digitizing and publishing historic essays and publications concerning Saxony's historical mining and metallurgical industry. Historical figures and scientific achievements A number of known figures studied and/or lectured at the Bergakademie: Abraham Gottlob Werner (1749–1817) was a highly influential lecturer and scientist, who systematized minerals and rock formations. He is considered the founder of an early form of geology as a science, called 'geognosis'. Thus, he laid the foundation for mineralogy and resource deposit theory. During his tenure, he attracted a wide range of students and peers, among them Alexander von Humboldt, Franz Xaver von Baader, Leopold von Buch, Friedrich Mohs, and Robert Jameson. Wilhelm August Lampadius (1772–1842) was a professor of chemistry and metallurgy. He installed the first gas light on the European continent and advanced the technology to an industrial scale. Also, Lampadius founded the world's first chemical research laboratory in a university in 1796/97. The poet Novalis (1772–1801; Georg Philipp Friedrich von Hardenberg) studied in Freiberg from 1797 through 1799. He also created his pseudonym for his literary works during this time. Many topics and themes of his work came from the mining culture surrounding him. The polymath Alexander von Humboldt enrolled on 14 June 1791 and
