Dr. Drew – The blood preservation pioneer

No. Not the guy on TV whose patients frequently passed away.

Charles Richard Drew (June 3, 1904 – April 1, 1950) was an American physician, surgeon, and medical researcher. He researched in the field of blood transfusions, developing improved techniques for blood storage, and applied his expert knowledge to developing large-scale blood banks early in World War II.

He received patent #2,301,710 on November 10, 1942 for a method of preserving human blood. Prior to Dr. Drew’s invention, transfusions required a nearly simultaneous exchange of blood from the donor to the patient before the blood became tainted. Dr. Drew discovered that plasma, which has a longer shelf life than blood and is less prone to contamination, could be separated from whole blood and used in transfusions, thus paving the way for the blood bank.
