Wassmannsdorf was active in "German South-West Africa" between 1895 and 1898. It is unclear whether he acquired objects himself during this period. Back in Berlin he collected "ethnographica" from all parts of the world and also lent it to local museums. Probably by exchange or donation within the Berlin colonial milieu, Wassmannsdorf acquired parts of the spoils of war from the storming of Hendrik Witbooi's residence Hornkranz in 1893. In 1902, Wassmannsdorf, on the advice of First Lieutenant Kuhn and with the aim of obtaining the award of an Order, donated 44 objects to the Verein für Handelsgeographie. Text: Christoph Rippe.
