Ernest Beutler (September 30, 1928 – October 5, 2008) was a German-born American hematologist and biomedical scientist. He made important discoveries about the causes of a number of diseases, including anemias, Gaucher disease, disorders of iron metabolism and Tay-Sachs disease. He was also among the first scientists to identify X-inactivation as the genetic basis of tissue mosaicism in female mammals, and pioneered a number of medical treatments, including bone marrow transplantation techniques.
