Hans-Georg Wenzel 1998

Hans-Georg Wenzel (born February 3, 1945 in Hahnenklee-Bockswiese , † November 11, 1999 in Wennigsen ) was a German geodesist , geophysicist and university professor. His most important field of work was physical geodesy , where he worked after completing his dissertation on earth tides with geophysical measurements and global models of the earth's gravity field .

Life

From 1962 to 1964 Wenzel trained as a surveying technician . Until 1967 he studied surveying at the State Engineering School for Civil Engineering in Essen and at the Technical University of Hanover , which he obtained in 1972 with the degree of Dipl.-Ing. completed. He then worked at the Institute for Earth Surveying at the University of Hanover, initially as a research assistant, later as a research assistant, senior engineer and finally as an academic adviser . In 1985 he completed his habilitation with his thesis High-resolution spherical function models for the earth's gravitational potential . In 1988 he was appointed professor of gravimetry and geodynamics at the Geodetic Institute of the University of Karlsruhe and director of the geoscientific joint observatory of the Universities of Karlsruhe and Stuttgart in Schiltach in the Black Forest, which was housed in the former Grube Anton mine . Since 1987 Wenzel has been active on the board of the International Association of Geodesy , of which he chaired the sections on gravity field determination from 1991 to 1995 and the International Earth Tide Commission from 1995 to 1999. From 1987 to 1995 he was also a member of the board of the International Gravimetric Office and since 1996 of the Federation of the Astronomical and Geophysical Data and Analysis Services (FAGS) . On March 1, 1999, Wenzel was appointed to succeed Professor Wolfgang Torge at the University of Hanover. Shortly after his appointment, he passed unexpectedly in late 1999.

Services

Hans-Georg Wenzel was known for many years in geodesy primarily for his groundbreaking development of the spherical function of the gravitational potential , which he began in 1984 and continued with ever higher resolution . They made an important contribution to geophysics and geodynamics , but also to regional and global geoid determination . In his research career, Wenzel published more than 150 publications on global ge tide research, earth gravity research and geodynamics. In May 2000 the Earth Tide Commission awarded Hans-Georg Wenzel the ETC Medal Award posthumously.
