After completing Gymnasium in the Rhineland, Heckmann entered the University of Bonn, completing a doctorate in 1925 with a thesis on the positions and proper motions of stars in the nearby cluster Praesepe, using plates taken at Bonn and under the directorship of Karl Küstner. That same year he married Johanna (née) Topfmeier who predeceased him by 2 years; they had three children.
For two additional years at Bonn, Heckmann worked on the theory of the dynamics of star clusters. (One of the important implications of his thesis observations and that theory is that
