Can someone please verify this for me? But I do believe that it was a black doctor who discovered blood types and the means to transfuse blood effectively. I also believe that ironically he died as the result of bleeding to death. I do recall that he had been in an accident and because he was a black man they would not transfuse *white blood* into him to save his life.
I dont recall the doctor's name and I am not 100% certain of the circumstances of his death, but I think I am correct.
Talk about irony... I do believe that is why this stuck in my mind.
