Dagstuhl is a computer science research center in Germany, located in and named after a district of the town of Wadern, Merzig-Wadern, Saarland. Location Following the model of the mathematical center at Oberwolfach, the center is installed in a very remote and relaxed location in the countryside. The Leibniz Center is located in a historic country house, Schloss Dagstuhl (Dagstuhl Castle), together with modern purpose-built buildings connected by an enclosed footbridge. The ruins of the 13th-century Dagstuhl Castle are nearby, a short walk up a hill from the Schloss. History The Leibniz-Zentrum für Informatik (LZI, Leibniz Center for Informatics) was established at Dagstuhl in 1990. In 1993, the over 200-year-old building received a modern extension with other guest rooms, conference rooms and a library. The center is managed as a non-profit organization, and financed by national funds. It receives scientific support by a variety of German and foreign research institutions. Until April 2008 the name of the center was: International Conference and Research Center for Computer Science (German: Internationales Begegnungs- und Forschungszentrum für Informatik (IBFI)). The center was founded by Reinhard Wilhelm, who continued as its director until May 2014, when Raimund Seidel became the director. The list of shareholders includes: German Informatics Society Saarland University Technical University of Kaiserslautern Karlsruhe Institute of Technology Technische Universität Darmstadt University of Stuttgart University of Trier Goethe University in Frankfurt Centrum Wiskunde & Informatica, Netherlands Institute for Research in Computer Science and Automation, France Max Planck Society In 2012, another new building was opened with 7 guest rooms. Since 1 January 2005, the LZI is a member of the Leibniz Association. Library Dagstuhl's computer science library has over 50,000 books and other media, among them a full set of Springer-Verlag's Lecture Notes in Computer Science (LNCS) series and electronic access to many computer science journals. Seminar series Dagstuhl supports computer science by organizing high ranked seminars on hot topics in informatics. Dagstuhl Seminars, which are established after review and approval by the Scientific Directorate, bring together personally invited scientists from academia and industry from all over the world to discuss their newest ideas and problems. Apart from the Dagstuhl seminars, the center also hosts summer schools, group retreats, and other scientific events, all discussing informatics. Every year about 3,500 scientists stay in Dagstuhl for about 100 seminars, workshops and other scientific events. The number of participants is limited to enable discussion and by
