Career

Dieter Lelgemann studied surveying at the engineering school in Essen and geodesy at the Technical University of Berlin , where he was a scientific assistant to Helmut Moritz after graduating and was awarded his doctorate in 1971. In 1975/76 he was on a study visit to the USA. He completed his habilitation in 1978 and was appointed professor for astronomical and physical geodesy at the Technical University of Berlin in 1985. In 2004 he retired .

In the 1970s and 1980s, Lelgemann worked at the Institute for Applied Geodesy in Frankfurt a. M. worked and researched the astro-gravimetric calculation of the quasi geoid for the Federal Republic of Germany (so-called "Lelgemann geoid"). He later became known for his new investigations of the world map of Claudius Ptolemy (see Geographike Hyphegesis ), using modern geodetic rectification methods to determine the location of the places indicated there - initially in the area of ​​today's Germany. He also wrote a book about Carl Friedrich Gauß as a geodesist and dealt with the importance of geodesy in antiquity , including copying devices such as the gnomon . He worked with the Berlin science historian Eberhard Knobloch .

In 2011 he was awarded the Eratosthenes Prize of the support group of the Museum of Surveying Technology in Dortmund. Lelgemann was a member of DVW Berlin-Brandenburg e. V. - Society for Geodesy, Geoinformation and Land Management and lived in Berlin.
