Who invented the blood storage system?

The blood storage system was developed by Dr. Charles Richard Drew, an American surgeon and medical researcher. In the 1940s, he pioneered techniques for the preservation and storage of blood plasma, which significantly improved the ability to store and transport blood for transfusions. His work laid the foundation for modern blood banks and transfusion medicine, saving countless lives. Drew's innovations were crucial during World War II, leading to the establishment of large-scale blood donation and storage programs.
