Mattheus Marinus Schepman

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. 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 genera of shelled freshwater, marine, and land molluscs. ==Published works==
