Eliza Ann Youmans (born in Greenfield, New York, 17 December 1826; died in Winona, Minnesota, 27 September 1914) wrote books, mainly on botanical subjects.
[1] To further her usefulness as a tutor, in 1843 she attended classes in chemistry given by William Mather in Fairfield, New York.
Later in New York City, with the same purpose in mind, she studied agricultural chemistry in the laboratory of Thomas Antisell.
[2] Her studies and tutoring stimulated her own interest in science, and her fondness for children led her to apply her knowledge to early education.
She prepared an enlarged edition of Henslow's Botanical Charts (1873), translated from the French Quatrefages' Natural History of Man (1875), and contributed to the Popular Science Monthly and other periodicals.
