Field Museum, Mollusk (FM-MOL)

Established in 1938, the Division of Invertebrates is in charge of all invertebrate groups except insects and other non-marine arthropods. The first curator of this Division was Fritz Haas, formerly of the Senckenberg Museum in Frankfurt, Germany. Haas (1938 - 1969) and his successor Alan Solem (1957 - 1990) built massive mollusk collections, particularly strong in unionid bivalves and terrestrial snails, reflecting their respective research interests. Current curators Rüdiger Bieler (1990 -) and Janet Voight (1990 -) focus their research and collection-building on marine molluscan groups.
