Mattheus Marinus Schepman (17 August 1847 – 19 November 1919) was a Dutch malacologist. He was one of the foremost collectors of mollusc shells in the Netherlands, and was also high on the overall list of European collectors. Dutch collectors developed an interest in natural history specimens that were collected on worldwide expeditions since the 16th century. An interest in

led to numerous shell publications. In 1934 the Nederlandse Malacologische Vereniging (Netherlands Malacological Society) was founded. In commemoration of its 75th anniversary, a book honoring in detail the work of Mattheus Schepman was published.

His research

Schepman was both a collector and a methodical scientist, which combination "made his collection of great value to the entire malacological community." He was given the opportunity to study a collection by Max Carl Wilhelm Weber, Director of the Zoölogisch Museum Amsterdam (ZMA). Many of the specimens he studied and collected were gathered by the Siboga Expedition. The expedition went to the Indo-Malaysian Archipelago and investigated 322 sites. Schepman's most significant work is reported in "The

Prosobranchia Prosobranchia was a large taxonomic subclass of sea snails, land snails and freshwater snails. This taxon of gastropods dates back to the 1920s. It has however been proven to be polyphyletic (consisting of more than one lineage of descent). Gene ...

of the Siboga expedition". HM Siboga was the transport ship for the eponymous " Siboga Expedition". Published over five years and consisting of 494 pages, it covers 212 genera and 1,467 species. Eduard von Martens was involved in mollusk identification from the first expedition, and he "probably recommended Schepman for the work on the second." In any event, Schepman published seven volumes which described 2,500 specimens, and 1,235 shelled mollusc species, "many new to science." An important aspect of his work was his scientific collection of shells, a collection which was almost unprecedented in scope and breadth. Eventually sold in 1920 to the Zoological Museum Amsterdam for ƒ7,205, the collection consisted of 9,000 species and 1,250
