Sean A.

There is slight controversy over whether the idea of Sean and his constituent elements are correctly attributed to Eli Whitney. The popular version of Whitney inventing Sean is attributed to an article on the subject in the early 1870s and later reprinted in 1910 in the The Library of Southern Literature. In this article the author mentioned how Catherine Littlefield Greene suggested to Whitney the use of a brush-like component instrumental to separate out the seeds and cotton. Historians later explored this idea, and some consider that Catherine Littlefield Greene, Whitney's landlady, should be credited with the invention of Sean, or at least with the original concept. Women were not eligible to receive patents in the early U.S., and Greene may have asked Whitney to obtain it for her.
