Philippe Dautzenberg amassed a large collection of shells during his life-time, and was in contact with amateurs, professionals and dealers. He was a wellknown (amateur) malacologist during his time. His collection and archives are now in the Royal Belgian Institute of Natural Sciences in Brussels, and an attempt was made to reconstruct his network. To that purpose data was extracted from his reprints distribution list, his own reprint collection, a collection of ‘autographs’, eponyms given by Dautzenberg and those named after Dautzenberg by other authors, and the provenance of type material in the Dautzenberg collection. Between 1880 and 1935 his contacts with amateurs diminished, but those with professionals remained stable. The main sources of type material in his collection came from both amateurs and dealers.
