Charles Drew was a brilliant doctor and scientist who helped save many lives! He studied how to keep blood safe and healthy so it could be given to people who were sick or hurt. Before Dr. Drew’s amazing work, it was very hard to store blood in hospitals. He figured out how to separate blood into parts and freeze it so it would last a long time!
Because of his clever ideas, Dr. Drew helped start the very first blood banks. These are special places where doctors keep blood ready for emergencies. His incredibly important work helped doctors and nurses care for thousands of people during times of need. He is a true hero in the world of medicine!
