Thomas, Edward Donnall

Edward Donnall Thomas, 1920–2012, American surgeon, b. Mart, Tex., M.D. Harvard, 1946. At the Univ. of Washington from 1963 (emeritus from 1990), Thomas performed (1969) the first successful bone marrow transplant between people who were not twins, using tissue crossmatching, radiation, sterilized environments, and immunosuppressive drugs to help prevent immune system complications and postoperative infection. For his innovations, which led to the use of the procedure as a standard treatment for leukemia in young people, he was awarded the 1990 Nobel Prize in Physiology or Medicine, which he shared with Joseph E. Murray, the first doctor to perform a successful kidney transplant. Known as the "father of the bone marrow transplant," Thomas built the Fred Hutchinson Cancer Research Center in Seattle, Wash., which he joined in 1974, into the world's largest bone marrow transplant unit.

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
