F. Wayne Grimm (21 June 1941 – 8 June 2005) was born in Philadelphia, Pennsylvania, U.S.A. His mother was Eugenia Stanley Grimm of West Virginia, and his father was Frank Gustav Grimm of Baltimore, Maryland. Wayne grew up in Baltimore and later attended Michigan State University on a Westinghouse Scholarship for Science. In 1954, he began his studies of terrestrial molluscs, mentored by Leslie Hubricht.
“Finding snails in secret places engages all of one’s faculties,” Wayne once wrote, “especially when one is committed to understanding them. Knowing the snails of an area means that one knows the whole history and general ecology.”
In the early 1970s Wayne immigrated to Canada and was employed in the design and display department of the National Museum of Canada (now Canadian Museum of Nature) in Ottawa. Most of his collection — up to about 1975 — was donated to the museum and forms comprises a significant part of the terrestrial gastropod holdings in that institution.
At some point Wayne lost interest in molluscs and took up other interests. He returned to his malacological studies around 1990, concentrating on the snails and insects of the eastern Ontario limestone alvars near his home. He was also contracted to survey alvars around the Great Lakes basin and summarized his knowledge of the fauna in his report, “Terrestrial Molluscs of the Mixedwood Plains Ecozone” (1996).
Wayne was Curator of Invertebrates at the now-defunct Eastern Ontario Biodiversity Museum (EOBM) from 1999 to his death. It was said that he had begun assembling data for a monographic revision of the fauna of Canada, but his progress was minimal and his later collections chaotic. Regardless, his death has left a major gap in Canadian malacology because, while his field experience was continental (especially in his earlier years) and his knowledge was encyclopedic, Wayne had published little in his later years. Wayne’s papers and most of his recent collections were moved to the Bishops Mills Natural History Centre for storage and curation when the EOBM closed shortly before his death. These collections are now being transferred permanently to the Canadian Museum of Nature, where they will join his earlier collection.
Wayne published approximately 25 zoological papers. Most of these were on molluscs, and appeared between 1959 to 1976 in The Nautilus, Bulletin of American Malacological Union, The Canadian Field-Naturalist, several other journals, and reports.

*In his 1996 report on the terrestrial molluscs of the Mixedwood Plains Ecosystem, Wayne Grimm that there were undescribed “new” species belonging to the genera Catinella, Cochlicopa, Columella, Discus, Glyphyalinia, Neohelix, Novisuccinea, Oxyloma, Pallifera, Succinea, Vertigo, andWebbhelix. None of these taxa, however, were ever published.
