Abstract

The nineteenth-century museum and auction house are seemingly distinct spaces with opposing functions: while the former represents a contemplative space that accumulates objects of art and science, the latter provides a forum for lively sales events that disperse wares to the highest bidders. This contribution blurs the border between museums and marketplaces by studying the Berlin Zoological Museum's duplicate specimen auctions between 1818 and the 1840s. It attends to the operations and tools involved in commodifying specimens as duplicates, particularly the auction catalogue. The paper furthermore contextualizes the museum's sales in a broader history of duplicate auctions across Berlin's collection landscape.
