On the occasion of the 80th birthday of Prof. Dr.-Ing. Günter Seeber and the 90th birthday of Prof. Dr.-Ing. Wolfgang Torge, the Department of Geodesy and Geoinformatics and the DVW Niedersachsen / Bremen e. V. will hold a festive colloquium (online event) on June 8 from 4 pm. The keynote speech will be held by Prof. Dr. Hermann Drewes from the Technical University of Munich on the topic "The Progress of International Geodesy after World War II".

Wolfgang Torge joined the "Institut für Theoretische Geodäsie" (Institute of Theoretical Geodesy) as director in September 1968. Günter Seeber was appointed "Professor für Geodätische Astronomie und Satellitengeodäsie" (Geodetic Astronomy and Satellite Geodesy) at the Institute in October 1973 and headed the Astronomical Station. From October 1982, the two colleagues alternated as executive directors of the now newly established Institute of Geodesy. In 1996 Professor Torge retired, Professor Seeber retired in 2006.

Wolfgang Torge’s research focused on the basics of geodesy, especially in the field of mathematical geodesy as well as with surveying networks, terrestrial gravimetry and geoid determination. In the 1990s, he was elected president of the International Association of Geodesy (IAG). He also made a name for himself as the author of the textbook "Geodesy" and other textbooks, some of which have been published in various languages.

Günter Seeber played a major role in the development of satellite methods in geodesy and was one of the first geodesists in Germany to recognize the potential of the Global Positioning System (GPS) for geodesy. He became known as the author of the standard work "Satellite Geodesy" and was considered an outstanding lecturer among students. He was also very active internationally, especially with regular visits to South America. He received several awards for his commitment in Brazil, including the title of professor honoris causa from the Federal University of Paraná.

Seeber and Torge organized extensive geodetic measurement campaigns worldwide, for example in Iceland, China and South America, and both used current measurement methods for geodetic applications.

Today, the Institute of Geodesy is still very active in the field of satellite geodesy and physical geodesy. The main focus is on GNSS-based positioning and navigation, terrestrial gravimetry, geoid determination, analysis of satellite data, and modeling of mass variations in the Earth system. The development of new measurement concepts for gravity field determination is carried out in a multi- disciplinary collaboration. Another flagship of the Institute of Geodesy is the analysis of laser measurements to the Moon.
