[1] From 1922 he was an assistant to Ludwig Mecking (1879–1952) at the University of Münster, where he habilitated in 1924 with a ground-breaking thesis on Standortfragen der Industrie des Thüringer Waldes.
After Creutzburg became professor by special appointment at the Gdańsk University of Technology in 1928, his research focus shifted, in that he devoted himself primarily to tasks and obligations of a regional and folklore nature.
In November 1933 he signed the Bekenntnis der Professoren an den deutschen Universitäten und Hochschulen zu Adolf Hitler.
Since he had been a NSDAP candidate and Wehrmacht officer before 1945, he was refused a return to the chair in Dresden and he switched to the University of Göttingen, where he taught geography from 1946 at the Institute of Hans Mortensen (1894–1964).
In 1948, Creutzburg received a professorship at the University of Freiburg, first as deputy chair and from 1951 as full professor and director of the Geographical Institute, where he retired in 1961.
