Who Discovered The Different Blood Types?

Karl Landsteiner

            

                Karl Landsteiner was a Viennese Physician who discovered the different types of blood. How? you may ask, well in the late 1800's people were dying from blood transfusions. At the time people thought of why people would die after a blood transfusion is, because of unknown disease. He thought differently, he believed maybe we all have different blood types, and He was right.

           How he prove his theory was, he and some of his colleagues (3) in 1901 did a experiment on their blood. The conclusion was that they definitely had different blood times, but what was weird that so it happened to be that everyone had a different blood type. Just imagine if 2/3 had the same type, maybe it wouldn't of led to his discovery. It would of  been a major fail if him, and his colleagues had the same blood type. It could of also not be discovered until 1981 when another Physician improve his discovery.

          He discovered Type A, type B, type O, and later type AB. How he figured it out, well its far from me to understand, but what I do know is each blood group have different Characteristics. Also you cant mix different blood types since one can be thicker than the other causing to clot in your arteries. O is the only universal blood type.

                                             
       
                    Due to his work, he saved thousands if not millions of peoples lives, if it wasn't for his curiosity it wouldn't of save people's lives still to this day. He later won the Nobel Prize in 1930. Sadly he later passed away on June 26, 1943 2 days previous to his death, he had a heart attack in his laboratory that led to his death.
