Diamond, Louis Klein


DIAMOND, LOUIS KLEIN (1902–1999), U.S. hematologist. Diamond was born near Kishinev, Ukraine, and immigrated to New York City at the age of two. He graduated from Harvard Medical School, Boston (1927), where he progressed to professor of pediatrics (1967). He was medical director of the new U.S. National Blood Program for blood transfusion (1948–50). After retirement from Harvard (1968) he remained professionally active first at the University of California, San Francisco, and then at the University of California, Los Angeles Medical School into his nineties. Diamond was one of the founders of pediatric hematology. With Kenneth Blackfan he clarified the clinical manifestations and treatment of rhesus incompatibility disease in the newborn, and they described an unrelated form of congenital anemia named after them. He was a world-renowned clinician and teacher.

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.
