German zoologist and collaborator of F. Poey in the natural history of Cuba and Puerto Rico. Established his personal cabinet of types in 1846; cooperated fully with other scientists by giving them his notes and descriptions of new species. After 1888 he moved his specimens to the Havana Museum, where he became the curator of their general collection. Shortly before his death, the Museum bought his specimens. His papers consist of lists and catalogues of Cuban Coleoptera and Hymenoptera contained in our collection number 366 and this series of papers consisting of 17 pieces and lists addressed to E. T. Cresson, Sr. Various notes about the collection as donated to the Academy are included.
