Wagner Jr. (August 29, 1920 – January 8, 2000), known as Herb Wagner, from his middle name, "Herbert," was an eminent American botanist who lived in Michigan. A longtime faculty member at the University of Michigan (Ann Arbor), he developed, in the early 1960s, the first algorithm for discerning phylogenetic relationships among species based upon their respective character states observed over a set of characters. This work was honored by James Farris and Arnold Kluge in their later appellation of related algorithms as "Wagner parsimony."Wagner specialized in the ferns, especially the Botrychiaceae. The standard botanical author abbreviation W.H.Wagner is applied to species he described.
