What medical discovery was made by Charles Drew?

Blood plasma fractionation

Charles Drew, an African-American physician and scientist, made significant contributions to the field of blood storage and transfusion. His most notable achievement was the development of a method for separating blood into its components, known as blood plasma fractionation. This process allowed for the storage of blood plasma and the production of plasma-based products, such as albumin, which were vital in treating wounded soldiers during World War II. Drew's work laid the foundation for modern blood banking and transfusion medicine, saving countless lives and revolutionizing the field of medical science.
