Hirszfeld completed his doctoral dissertation, "Über Blutagglutination," in 1907, thus taking the first step in what was to become his specialty. But first he became a junior assistant in cancer research at the Heidelberg Institute for Experimental Cancer Research, where E. von Dungern was his department head.

At Heidelberg they did the first joint work on animal and human blood groups which, in 1900, had been identified as isoagglutinins by Karl Landsteiner. Von Dungern and Hirszfeld examined 348 individuals from 72 families and showed that blood groups A and B did not occur in the offspring unless they were present in at least one of the parents, fulfilling the Mendelian principles of inheritance. They also showed that A and B are dominant, while O is a recessive trait. In addition, they…
