Ludwik Herszfeld

Ludwik Herszfeld (1884 - 1954) Polish microbiologist and serologist, who along with colleague Emil von Dungern, a German internist, discovered the inheritance of ABO blood type. He was also the first to suggest the ABO naming for Karl Landsteiner's discovery of blood groups, which were originally named I, II, III and IV. Herszfeld also discovered the bacillus Salmonella paratyphi C, today called Salmonella herszfeldi. As a serologist, he was also the first to forsee a serological conflict between mother and developing fetus, which was confirmed by the discovery of Rhesus factor.
