The late Professor Willard Hartman (1921-2013) spent nearly his entire academic and professional life at Yale University. He arrived as an undergraduate in 1939, eventually earning his B.S. M.S. and Ph.D. degrees from Yale. His dissertation focused on the natural history of New England sponges, and thereafter sponges have been his primary research interest. In 1950 he moved to California and was an Instructor in Zoology at the University of California, Berkeley. In 1953 he returned to Yale and began his long professional career as an Assistant Professor of Zoology, and Curator in the Yale Peabody Museum, eventually becoming a full professor in 1973. Appointed Acting Director of the Museum in 1987, he became its Director in 1990 (fall term).
