What blood type did Karl Landsteiner have?

Initially, Landsteiner recognized three different blood types: A, B, and C. The C-blood type was later more commonly called type-O. In 1902, one of Landsteiner’s students found a fourth blood type, AB, which triggered a reaction if introduced into either A or B blood.

What are the 4 main blood groups?

There are 4 main blood groups (types of blood) – A, B, AB and O. Your blood group is determined by the genes you inherit from your parents. Each group can be either RhD positive or RhD negative, which means in total there are 8 blood groups.

Who discovered blood types in 1901?
