The original blood group pioneers: the Hirszfelds

Ludwik Hirszfeld, together with his wife Hanka, was the first to study the blood groups in large numbers of subjects (soldiers) during World War I at the Macedonian front. They found significant differences in the distribution of the ABO blood groups, that is, type A was more common in soldiers from North Central Europe, whereas type B was more common in those from Eastern Europe. Their data were later (in the 1920s and 1930s) misused by German nationalists to support the concept of Aryan supremacy. The Hirszfelds also discovered Salmonella paratyphi C, now known as Salmonella hirzfeldi. Their landmark studies drew others to this new field of seroanthropology, most notably Arthur Mourant, as well as Robin Race and Ruth Sanger, who wrote "Blood Groups in Man" detailing the antigenic differences among various peoples.
