Hans Aronson (28 November 1865 – 8 March 1919) was a German pediatrician and bacteriologist.
He studied medicine in Königsberg and Berlin, and, as a student, he became an assistant of Paul Ehrlich.
In 1893, he became the first director of the newly established Department of Bacteriology at Schering AG.
In this capacity, he developed one of the first successful commercially produced antitoxic antisera against diphtheria, based largely on the basic research of Emil von Behring, but in competition with Behring himself.
[1][2] He died in Dresden and is interred at the Jewish Weißensee Cemetery in Berlin.
