Founded in 1846 under the name of Royal Saxon Society for the Sciences, the Saxon Academy of Sciences in Leipzig, like its sister institutions, is rooted in the idea of the academy formed by Leibniz to unite "theoriam cum praxi". More than 200 scientists of all disciplines meet regularly to exchange views, examine methods and results of specialist studies in interdisciplinary discussion and engage in long-term basic research. Ordinary Fellows of the Saxon Academy must be habitually resident in Saxony, Saxony-Anhalt or Thuringia at the time of election. Right now, the Academy is responsible for more than 20 research projects especially in the humanities but also in the natural sciences and in engineering, most of which are carried out in close cooperation with universities and other non-university research establishments. The Academy looks back on a particularly long tradition concerning the compilation of dictionaries. They cover a broad range of languages and dialects including, for example, Ancient Egyptian, Old High German and large-area dialects. The Academy's research also focuses on history and regional studies. Among its regular projects is the edition of collections of sources and maps relating to Central Germany's history. Its main topics are the importance of the region as a centre of European Enlightenment, the history of the Lutheran Reformation and its worldwide effects, as well as Slavic-German cultural relations and the European response to Central German legal sources. Here, annotated editions of collected works and editions of letters also deserve to be mentioned, as well as studies from the field of the history of science. In the natural sciences the Academy carries out basic research in the fields of anatomy, environmental studies, geology and geo-ecology. In 1997, the Academy set an additional trend in accepting short-term research projects related to technology assessment. President of the Saxon Academy of Sciences in Leipzig is Professor of Philosophy Pirmin Stekeler-Weithofer.
