He was emeritus professor for dynamic and historical geology at the Bergakademie Freiberg . He was known worldwide as one of the most important paleontologists for marine fossils of the Cretaceous Period.

Life

His father Carl Herbert Tröger (1904–1945) was the technical director of a tannery in Melun, then came to Russia, was wounded and returned to Dresden at the age of 42. His mother was Anna Sophie Charlotte Grimm (1904–1986), she came from the Westphalian gardener family in Mecklenburg, who had moved to Plauen. Karl-Armin Tröger came to Dresden via Plauen in 1939, attended elementary school in Dresden from 1939 to 1941, from 1942 to 1945 the secondary school in Dresden, graduated from high school for boys in Dresden-Nord in 1950 and studied geology from 1950 to 1955 , Mineralogy and geophysics at the Bergakademie Freiberg. He wrote his diploma thesis on sediment petrographic and biostratonomic-paleontological investigations of the chalk of the Plauen reason in Dresden.

1955 assistant at the Bergakademie, Freiberg, 1959 doctorate, 1959 to 1961 geological service of the GDR, branch Saxony, 1961 Bergakademie Freiberg, 1965 habilitation, 1966 lecturer for practical and theoretical stratigraphy, 1975 to 1976 study visit to the Soviet Union. 1989 C4 professorship, 1992 appointment as C4 professor for dynamic and historical geology until 1996 at the Bergakademie Freiberg. 1990 to 1994 member of the Senate of the Bergakademie, Dean of the Faculty of Mathematics and Natural Sciences and Director of the Geological Institute of the Bergakademie Freiberg.

His specialties were Cretaceous research and the Paleozoic . Tröger was known as a connoisseur of the Nossen-Wilsdruffer slate mountains and the so-called Weesensteiner group ; the mapping and publication of the geological maps of Saxony on a scale of 1: 25,000 took place with his authoritative participation. Many of his more than 200 publications appeared in Freiberg's research books , he also published in the papers of the State Museum for Mineralogy and Geology in Dresden . He supervised 8 doctoral and 36 diploma theses.

In 1973 he was elected a member of the German Academy of Sciences Leopoldina .

Karl-Armin Tröger was one of the so-called " gap professors " who did not have civil servants and for whom there was no supplementary pension despite high earnings in the reunification of Germany, as this is not regulated in German pension law.
