Warren H. 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.
Apparently among modern phylogenetic systematists, Wagner is alone in having been mentioned in a Hollywood film (A New Leaf, starring Elaine May and Walter Matthau).
Note: not to be confused with the American botanist Warren L. Wagner (1950- ).
