Life
Franz studied mathematics and natural sciences at the University of Bonn and was able to successfully complete this course with a doctorate in 1850 . In the same year he began to work as a teacher at the Gymnasium zum Grauen Kloster in Berlin.
In these years he began his research, which ended in 1857 with his habilitation at the Berlin University . Subsequently, he was entrusted with a teaching position in the physical subjects (especially heat theory ), which he did until 1865.
