Between 1820 and 1850, the Dutch government sent several scientists to the Netherlands Indies as part of the Natuurkundige Commissie (Natural History Committee). One of these was naturalist Eltio Alegondus Forsten (1811–1843), who was sent on a collecting mission to Celebes (Sulawesi). This paper explores the ways in which Forsten was in a relationship of mutual interdependence with four spheres of influence, two in the Netherlands (those of the Dutch government and the natural history museum in Leiden) and two in (...) the Dutch East Indies (those of the governor-general and the local population of Forsten's collecting grounds). These four entities served as focal points for Forsten's practice, and tried to use his mission for their own purposes. At the same time, Forsten negotiated their demands deftly and turned them to his own advantage in order to serve his own future career. Throughout, I draw parallels with the experiences of various other members of the Natural History Committee. I ultimately propose that this case study of Forsten provides a glimpse of a possible pattern for the relationship between government-sponsored science and empire in the Dutch East Indies in the first half of the 19th century.
