Thomas, Cyrus

Cyrus Thomas, 1825–1910, American anthropologist and entomologist, b. Kingsport, Tenn. He was a lawyer, then a minister (1865–69) of the Evangelical Lutheran Church. He was associated with the U.S. Geological and Geographical Survey of the Territories from 1869 to 1873. As state entomologist of Illinois (1874–76) and a member of the U.S. Entomological Commission (1876–77), he helped bring under control the insect plague that was retarding the agriculture of the border states. In 1882 he left natural science for social science, becoming archaeologist to the newly established U.S. Bureau of Ethnology, where he served until his death. Besides numerous articles on entomology and archaeology, he wrote Introduction to the Study of North American Archaeology (1898) and The Indians of North America in Historic Times (1903).

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.
