TheSiboga Expedition
Weber'slastand mostimportant travelventure was
the Siboga Expedition. He had been one of the
initiators of the Society for the Advancement of
Scientific Researchinthe Netherlands'Coloniesin
1889. One of the most important initiatives taken
by this Society (now called Treub Maatschappij,
afterthe botanist Melchior Treub) was theorgani-
zationoftheSibogaExpedition. Consequently, the

of theMalayan Archipelago was launchedin May
1896. At a meeting on 19 September of the same
year Weber declared himself willing to accept the
leadership ofanexpedition withtheobject to study

cially of its deep basins (Sluiter, 1897; Weber,
