Have you ever wondered why your body only accepts a certain blood type? Where did the concept come from? Well, it’s all because Karl Landsteiner, and Austrian and American biologist, discovered the blood groups in 1901. He died in June 1943.
Landsteiner discovered four blood types A,B, AB and O, and it was only six years later in 1907 that the first successful blood transfusion took place because of his discovery.
Not only did he discover blood types, Landsteiner also lay the foundation, that led to the discovery of the polio virus, along with scientist Erwin Popper.
Reportedly, blood transfusions took place in the 17th century between animals but when animal blood was attempted to transfuse in a human body, it refused to accept it and proved to be fatal. In some cases, when it did happen successfully, it was merely by chance.
“On what would be his 148th birthday, we thank you, Karl Landsteiner, for helping us lead longer, healthier lives,” says a Google post on the biologist.
