In the 19th and early 20th centuries, patients diagnosed with "pernicious" (meaning deadly) anemia faced a grim prognosis. The journey to a cure began with George

The journey to a cure began with George Whipple , who was studying blood regeneration in anemic dogs. Due to a happy laboratory accident where a technician fed the dogs raw liver instead of cooked food, Whipple realized that . agonizing decline marked by severe pallor

Hearing of this, Boston physicians George Minot and William Murphy decided to try feeding raw liver to human patients dying of pernicious anemia.
