Why Is Charles R. Werth Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Charles Richard Werth was an American botanist who studied the evolution of numerous plant taxa through isozyme analysis. Background 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 began his post-secondary education at the University of Virginia, which granted him a BA in biology in 1969. He taught middle school science and mathematics at various schools in Virginia from 1969 to 1976. During this time, he received an MA in secondary education in 1973 and subsequently received another MA in biology from the University of Virginia in 1978 or 1979.
