scientist Karl Landsteiner is widely credited to have discovered the ABO blood grouping system,
who identified the O, A, and B blood types in 1900.

Landsteiner
originally described the O blood type as type “C”, it was later
rendered as “0” (zero), signifying the lack of A or B antigen. He was
awarded the Nobel Prize in
Physiology or Medicine in 1930 for his work. Due to inadequate communication at the time, it
was subsequently found that the Czech serologist Jan Jansky had independently
discovered and pioneered the classification of human blood into four (4)
groups, but Landsteiner’s independent discovery had been accepted by the
scientific world while Jan Jansky
remained in relative obscurity (Ogasawara, 2006).

The
designation A and B with reference to blood groups was proposed by Ludwik Hirszfeld. In America, W.L. Moss published his own (very
similar) work in 1910 (Moss, 2011).

Ludwik Hirszfeld and Evon Dungern discovered the heritability of ABO blood groups in
1910–11. Felix Bernstein demonstrating the correct blood group inheritance pattern of multiple alleles at one locus in 1924 (Crow, 2003).

Watkins
and Morgan, in England, discovered that the ABO epitopes were conferred by sugars, to be specific, N-acetylgalactosamine for the
A-type and galactose for the B-type (Morgan and Watkin, 2010).
