Charles Richard Werth (25 September 1947 – 27 July 2001) was an American botanist who studied the evolution of numerous plant taxa through isozyme analysis.
Born in Seoul, Korea, Werth and his family moved to Falls Church, Virginia in 1950, where he grew up and graduated from high school in 1965.
Werth's doctoral work involved the genetics of a group of ferns known as the "Appalachian Asplenium complex", which included a large number of hybrid species.
[1] Werth continued to study the technique of isozyme electrophoresis, demonstrating that it could be used, under certain conditions, with dried herbarium material as well as fresh plant specimens.
[4] Werth was appointed an associate professor in Biological Sciences at Texas Tech University in 1987; he was also made curator of the R. L. Reed Herbarium there.
