Francis La Flesche (1857-1932) lived between two worlds: as an Umonhon (Omaha), he fought for their rights, and as a scholar he researched his own culture. He is regarded as the first indigenous ethnologist of North America and stands representatively for the many indigenous protagonists without whom ethnological collections would never have come into being. We are no longer familiar with most of these individuals, since the focus until today has been on European and North American collectors. Francis La Flesche is an exception: his work provides insights into indigenous agency and their resistance to racism and colonialism as well as their active participation in the trade with objects. The book presents La Flesche's records of the objects, the collection of which he contributed to what is today the Ethnological Museum in Berlin in 1894-an impressive testimony to his successful efforts to preserve the culture of the Omaha for future generations.
