Blood bag inventorDavid Bellamy

As an assistant to a Harvard Medical School’s Professor Carl Walter, Bellamy helped with a number of medical inventions. But he, with Dr. Walter, made perhaps their biggest contribution when they came up with plastic containers for blood — blood bags. They innovation not only helped with storage and sterility of blood and other products, but made blood collection and the delivery of other fluids easier and virtually break proof. Bellamy died August 29 from brain cancer. He was 74.
