The Rhesus system is named after the Rhesus Macaque, following experiments by Karl Landsteiner and Alexander S. Wiener, which showed that rabbits, when immunized with rhesus monkey red cells, produce an antibody that also agglutinates the red blood cells of many humans. Landsteiner and Alexander S. Wiener discovered this factor in 1937 (publishing in 1940).
