George H. WhippleBorn 28 Aug 1878; died 1 Feb 1976 at age 97.George Hoyt Whipple was an American physician and pathologist who shared the 1934 Nobel Prize for Physiology or Medicine with George R. Minot and William P. Murphy for “their discoveries of a treatment of pernicious anemia with a special diet of liver.” Whipple began a study in 1920 of the influence of food on blood regeneration. From experiments on dogs bled to reduce blood volume, he found the best food to stimulate the bone marrow for the production of the new red blood corpuscles was raw liver. Other foods, including kidney and apricots were also found helpful. Minot and Murphy applied Whipple's discovery of the value of liver. They designed a special diet for humans with a particular noninfectious disease - pernicious anemia. The three researchers made a major advance with a non-drug treatment of this condition.« |
