The Development of different types of Blood.

Karl Landsteiner developed Modern Classification of Blood Types.

In 1900 he found out that the blood types of two people under contact agglutinates and in 1901 he found this effect was because of the contact of blood with blood serum. As a result he succeeded in identifying the three types of blood groups A, B, & O, which he labelled C of human blood. He also found out that blood transfusion between people with the same blood type did not lead to destruction of the blood cells, which happens with people with different blood types.
