He was smart. He was outspoken and he did not give up. Dr. Charles Drew was a highly intelligent man. It was him who stood against the US Army when they segregated the blood of both black and white donors. It was also him that came up with the collection and processing of blood plasma which ultimately saved the lives of many in the war.
Dr. Drew could have easily been accepting of the policy and returned to his research or the next great advancement in his research, but he took a stance for what was right. This man did awesome work and made great contributions to the world of healthcare and science.
