The brothers undertook their expedition at a time of profound epistemological transformation in the areas of field research and the study of foreign cultures. Humboldt’s correspondence with the Schlagintweit brothers documents a paradigm shift in media history from natural painting to photography. The extensive collections of the Schlagintweits were initially intended, with Alexander von Humboldt's support, for a planned Indian Museum in Berlin's Monbijou Palace, but soon became the object of dispute between British colonial authorities and the Prussian museum administration.
