Northwestern University Library has just made available a magnificent, and freely accessible, collection of thousands of rare photographs chronicling Europe's colonization of East Africa. The collection, The Humphrey Winterton Collection of East African Photographs: 1860-1960, numbers over 7000 photographs and all are searchable because of extensive metadata.
The photographs “include formal and informal portraits of Africans and their colonizers, photos of slaves and slave traders, and images depicting the building of railroads and urban areas and of traditional African life.
They represent the work of explorers, colonial officials, settlers, missionaries, military officers, travelers and early commercial photographers.”
