1962 doctorate toads Heerdt at the Martin Luther University of Halle-Wittenberg for Dr. rer. nat. with a thesis on the subject of a special type of alternating knot . His doctoral supervisor was Ott-Heinrich Keller . In 1968, Krötenheerdt completed his habilitation with a thesis on the subject of the homogeneous mosaics of the nth order in the Euclidean plane .

In 1968 he was a lecturer at the Martin Luther University in Halle-Wittenberg. In 1969 a chair for geometry was set up there to which Krötenheerdt was appointed as a full professor. From 1969 to 1994 Krötenheerdt was a mathematics professor for geometry at the Martin Luther University in Halle-Wittenberg. In 1994 he retired.

Krötenheerdt was married and had children, grandchildren and great-grandchildren. He had a younger brother, Johannes Krötenheerdt (1933-2014), who was also a professor in Halle.
