Carl Johan Schönherr

Carl Johan Schönherr was a Swedish entomologist who revised the taxonomy of beetles, including weevils by examining all the descriptions of beetles since the time of Linnaeus. He began with an examination of the Charles de Geer collection which had been handed to the Swedish Academy of Sciences in 1778. He introduced the system of using a red label to mark historical specimens that had served as the basis of De Geer's descriptions. This continues to be a standard practice in entomological collections today for holotypes.
