Page  124 ï~~124 THE MICHIGAN BOTANIST Vol. 41 OBITUARY Howard A. Crum (1922-2002) The Great Lakes botanical community lost a highly regarded colleague with the passing of Dr. Howard Crum on 30 April 2002. Virtually anyone who studied mosses, lichens, or peatlands in the Great Lakes region has probably come in contact with Dr, Crum, either in person, in the classroom or the field, or from reading one of his many articles and books. Members of the Botanical Club may also remember Howard as the second editor of The Michigan Botanist, taking over the reins from Dr. Edward Voss in 1977 and continuing until 30 April 1984. Howard received his B.S. from Western Michigan University in 1947, completing his graduate degrees at the University of Michigan (M.S. in 1949, Ph.D. in 1951). His "Michigan connection" resumed when he returned to the University of Michigan in 1965 as an Associate Professor of Botany and Curator of Bryophytes at the UM Herbarium. Over the next 35+ years, he did many things to both advance our knowledge of the bryophytes of our area as well as impart this knowledge to others. Howard taught courses about mosses, lichens, and peatland ecology both on the main campus in Ann Arbor and at the Biological Station at Pellston, continuing to spend summers there after his official retirement as Curator Emeritus in 1995. While much of his research dealt with the classification and distribution of the genus Sphagnum (peat mosses), he also ranged more broadly among the bryophytes of the Great Lakes region. His book Mosses of the Great Lakes Forest, a definitive work which first appeared in 1973, is still used as a text in several college classes. Howard was working on a fourth revision of the work at the time of his passing. The other volumes that Howard wrote which involve Great Lakes subjects are his Liverworts and Hornworts of Southern Michigan (1991) and A Focus on Peatlands and Peat Mosses (1988). While I have just touched on a few of the highlights of his career, readers who would like to read an extensive account of his life and a bibliography (to 1992) should consult the following article: Anderson, L.E. 1992. A tribute to Howard Crum. Contributions from the University of Michigan Herbarium 18: 3-38. This article was written by one of Howard's colleagues as an introduction to a collection of papers assembled as a celebration of Howard's 70th birthday. Richard K.
