Background
If a person loses a lot of blood-either from a wound or during surgery-he or she may be given a blood
transfusion. Most early attempts at blood transfusion failed, but no one knew why until the early
1900s. Karl Landsteiner, an Austrian American physician, had led to a better understanding of
transfusions.
