Helmut Moritz was born in [[Graz|Graz, Austria]] as only son of Josef and Karoline Moritz. His father Josef Moritz was a calibration officer and killed in action in France during the Second World War in 1944. Helmut Moritz studied geodesy at the [[Graz University of Technology]] (TH Graz) from 1951 to 1956, graduating in 1956 with a degree in Surveying. From 1955 to 1958, he worked as a research assistant at the TH Graz; in 1959, he was awarded a Dr. techn. degree by [[Sub auspiciis Praesidentis]]. From 1958 to 1964 he was employed in Graz as an official of the Federal Office of Metrology and Surveying (Bundesamt für Eich- und Vermessungswesen, BEV). In 1960, he received his habilitation at the Graz University of Technology.

In 1962, he became a Visiting Research Associate at the Department of Geodetic Science at [[Ohio State University]] (OSU) in [[Columbus, Ohio]], US. His research was strongly supported by Professor [[Veikko Aleksanteri Heiskanen|Weikko A. Heiskanen]]. Moritz became internationally known with a fundamental work on [[Error propagation]] in Geodesy. He studied publications by the mathematicians and cyberneticists [[Norbert Wiener]] and [[Andrey Kolmogorov|Andrei Nikolayevich Kolmogorov]], and expanded his academic teaching in theoretical geodesy. This was later reflected in the book Physical Geodesy, co-authored with Heiskanen; this work was translated from English into Chinese, Serbo-Croatian, Spanish, and Turkish and became a geodetic bestseller. His first research appointment at [[Ohio State University]] thus opened up long-term perspectives for Moritz; he has remained in professional contact with this university for more than 20 years.

In 1964, he initially returned to the BEV in Graz, and soon after became a private lecturer at the TH Hannover. Here he continued his work on the geodetic boundary value problem of the great Russian geodesist [[Mikhail Molodenskii]] for the determination of the Earth's shape from measurements of gravity and gravitational potential. Moritz was appointed Full Professor of [[Physical geodesy|Physical Geodesy]] at the Technical University of Berlin in 1964. In 1971, Moritz received a call as Full Professor at the [[Graz University of Technology|Technical University of Graz]] where he remained until his retirement in 2002.

In Moritz's career, his international activities played an increasing role; he speaks several foreign languages: English, French, Italian, Polish, Russian, Serbian, Croatian, Slovenian, Spanish, and Czech. His early activities in the German Geodetic Commission led to his election as chairman as early as 1965. He became chairman of a study group of the [[International Association of Geodesy]] (IAG) on fundamental Earth constants, which have not only geodetic but also astronomical, geophysical, and geographical significance. Moritz served as president of the IAG during the 1979 to 1983 term. From 1991 to 1995, he was president of the [[International Union of Geodesy and Geophysics]] (IUGG).

Helmut Moritz, 2012

Helmut Moritz (1 November 1933 – 21 October 2022)[1] was an Austrian physical geodesist. He became internationally known for fundamental work on error propagation in geodesy. He was a member of the Austrian Academy of Sciences and many other international academies and societies. From 1991 to 1995, he was president of the International Union of Geodesy and Geophysics (IUGG).

Early life and education

Moritz was born in Graz, Austria as the only son of Josef and Karoline Moritz. His father was a calibration officer who was killed in action in France during the Second World War in 1944. Helmut studied geodesy at the Graz University of Technology (TH Graz) from 1951 to 1956, graduating in 1956 with a degree in Surveying. From 1955 to 1958, he worked as a research assistant at the TH Graz; in 1959, he was awarded a Dr. techn. degree by Sub auspiciis Praesidentis. From 1958 to 1964 he was employed in Graz as an official of the Federal Office of Metrology and Surveying (Bundesamt für Eich- und Vermessungswesen, BEV). In 1960, he received his habilitation at the Graz University of Technology.

Career

In 1962, he became a Visiting Research Associate at the Department of Geodetic Science at Ohio State University (OSU) in Columbus, Ohio, US. His research was strongly supported by Professor Weikko A. Heiskanen. Moritz became internationally known for fundamental work on error propagation in geodesy. He studied publications by the mathematicians and cyberneticists Norbert Wiener and Andrei Nikolayevich Kolmogorov, and expanded his academic teaching in theoretical geodesy. This was later reflected in the book Physical Geodesy, co-authored with Heiskanen; this work was translated from English into Chinese, Serbo-Croatian, Spanish, and Turkish and became a geodetic bestseller. His first research appointment at Ohio State University thus opened up long-term perspectives for Moritz; he remained in professional contact with this university for more than 20 years.

In 1964, he initially returned to the BEV in Graz, and soon after became a private lecturer at the TH Hannover. Here he continued his work on the geodetic boundary value problem of the great Russian geodesist Mikhail Molodenskii for the determination of the Earth's shape from measurements of gravity and gravitational potential. Moritz was appointed Full Professor of Physical Geodesy at the Technical University of Berlin in 1964. In 1971, Moritz received a call as Full Professor at the Technical University of Graz where he remained until his retirement in 2002.

During his time in Graz, Moritz compiled and carefully structured the mathematical and statistical foundation of collocation in all its facets in his fundamental book Advanced Physical Geodesy (1980). Jointly with Ivan I. Mueller he wrote the volume Earth Rotation: Theory and Observation (1987). His book Geometry, Relativity, Geodesy (1992), jointly written with Bernhard Hofmann-Wellenhof, may be considered a sort of bridge building, starting from the curved surface, known to every contemporary geodesist, towards the curved space. His book Science, Mind and the Universe (1995) can be understood as a demanding journey into the vast dimensions of our universe, and its reflection by our human mind, enriched by a glimpse on the special and general theory of relativity and quantum physics. And finally, a strong international demand for a revised new edition of his fundamental early book Physical Geodesy, now jointly with B. Hofmann-Wellenhof, closed the circle of his scientific volumes.[1]

In Moritz's career, his international activities played an increasing role. He spoke several foreign languages: English, French, Italian, Polish, Russian, Serbian, Croatian, Slovenian, Spanish, and Czech. His early activities in the German Geodetic Commission led to his election as chairman as early as 1965.

Moritz served as president of the IAG during the 1979 to 1983 term. From 1991 to 1995, he was president of the International Union of Geodesy and Geophysics (IUGG).

Moritz received three honorary doctorates: in 1981 from the Technical University of Munich, Germany; in 1992 from the Ohio State University, and in 1994 from Moscow University of Geodesy, Aerophotogrammetry and Cartography, Moscow, Russia.

He received awards worldwide, including the Carl Friedrich Gauss Medal in 1977 and the Alexander von Humboldt Medal. He was a member of many national and international professional associations and academies of sciences.

Helmut was married since 1959 to Gerlinde Moritz, who passed away in 2002. The couple has two children, Berta (* 1960) and Albrecht (* 1962), who became biologists and biochemists, respectively. Helmut's fields of private interest covered hiking, languages, German literature, philosophy of science and the dialogue between science and faith.[1][2] After a reversion to his faith, Moritz was a practicing Catholic.[3]
