William Murphy, American Medical Researcher

William Parry Murphy (February 6, 1892 - October 9, 1987) was an American physician and medical researcher who shared the Nobel Prize in Physiology or Medicine in 1934 with george Minot and George Whipple for their combined work in devising and treating anemia. He completed his A.B. degree in 1914 from the University of Oregon. He completed his M.D. in 1922 from Harvard Medical School. In 1924, Murphy bled dogs to make them anemic, and then fed them various substances to gauge their improvement. He discovered that ingesting large amounts of liver seemed to restore anemia more quickly of all foods. Minot and Whipple then set about to chemically isolate the curative substance. The active ingredient, found serendipitously, was not iron, but rather a water-soluble extract containing a new substance. From this extract, chemists were ultimately were able to isolate vitamin B12 from the liver. Even before the vitamin had been completely characterized, the knowledge that raw liver and its extracts treated pernicious anemia (previously a terminal disease) was a major advance in medicine. He died at the age of 95.
