Louis Hermann Pammel

Louis Hermann Pammel (1862–1931) was an American botanist, conservationist, and professor of botany.

Biography Louis Hermann Pammel was the second of six children and the oldest son of his parents who were Prussian immigrants to Wisconsin. In 1885 he graduated with a bachelor's degree in agriculture from the University of Wisconsin–Madison, where William Trelease taught him in courses in ecology, cryptogamic botany, and botanical taxonomy. In July 1885 he became employed in a Chicago seed company. In October 1885 he became a medical student at Philadelphia's Hahnemann Medical College. However, he soon accepted an offer to work as an assistant to the botanist William G. Farlow at Harvard University and arrived in Cambridge, Massachusetts in early December 1885. In the spring of 1886 Pammel received a letter from William Trelease, his former botany professor at Wisconsin, who had moved in 1885 to Washington University in St. Louis. The letter offered Pammel an assistantship at the Shaw School of Botany with a salary of $50 per month for the eight months of the academic year. He accepted and began work there in the fall of 1886.

He was president of the Iowa Academy of Science in 1892–1893 and again in 1923–1924. and Ada Hayden. Hordeum pammelii Scribn. & Ball (a grass) Senecio pammelii Greenman (a composite)
