After discovering that leukemia patients were often bleeding to death because they had insufficient platelets, Dr. Freireich developed and patented the first continuous-flow blood cell separator.

His daughter, Lindsay Freireich, said, “Out of all the oncologists in the world, he decided to use his own plasma and combine chemotherapies so that children’s leukemia went from 100% death to 97% life.”
