Provenance Research and Restitution in Colonial Scientific Contexts

This historical photograph has been deliberately obscured to avoid renewed public display of deceased persons held by the University. It refers to earlier archival registration practices that marked individuals from colonial contexts with signatures and inventory numbers. “M 0001” refers to the archival classification “Musealia”, which the University no longer uses. Showing the image unobscured without prior consultation and consent would risk reproducing the objectification of these people this research seeks to address.

Not objects. People.

The University of Freiburg acknowledges its historical responsibility for deceased individuals who came into university custody through colonial, racializing and anatomical-anthropological research contexts. Provenance research on victims of colonial violence in the care of the University, and the preparation of possible repatriations, are therefore matters of university-wide responsibility.

The historical anthropological collection of the University of Freiburg originated in the nineteenth century. Founded in 1857 by the anatomist and anthropologist Alexander Ecker and expanded by later successors, it eventually comprised more than 1,500 deceased persons. Many remained unnamed in the surviving documentation. Some were killed in colonial contexts of violence; others were taken from graves after death. They were brought to Freiburg and used for anatomical and anthropological research.

The surviving records often did not preserve names, biographies, kinship relations or personal histories. Historical inventories reduced people to numbers, geographical attributions and body-related classifications. The University’s provenance research therefore seeks, as far as possible, to reconstruct origins, contexts of violence, relationships and biographical traces, while making the limits of the surviving documentation transparent.

“We deeply regret what was done at the University of Freiburg in the guise of science. Unfortunately, we cannot undo the injustice and suffering committed by researchers in the past. But we will do everything we can to help heal the wounds and return the ancestors to their homeland.”

The deceased persons who were originally displayed there have been removed in this digital composition. The image makes the historical exhibition logic visible without showing the dead again.

Historical and Post-Colonial Responsibility

The project is institutionally located at the Rectorate for University Culture and is therefore not subordinated to a single disciplinary institute. This structure is significant: the historical responsibility addressed here concerns the University as a whole. Current work does not continue the logic of a historical collection, but subjects it to critical reappraisal.

The deceased individuals are no longer understood as scientific objects. They are people whose names, life stories, relationships and social belonging were often erased by colonial and racializing knowledge systems. Provenance research is intended to support further repatriation processes where such processes are methodologically responsible, possible and desired by the relevant communities or states of origin.

Previous Repatriations

In close cooperation with the Ministry of Science, Research and the Arts Baden-Württemberg and international partners, the University of Freiburg has already participated in several repatriations. Further provenance clarifications and repatriation procedures are in preparation.

Namibia, 2014The University of Freiburg returned deceased persons to Namibia after provenance research had established a high probability of origin in the territory of present-day Namibia.
Australia, 2019The University of Freiburg participated in the return of people to Aboriginal and Torres Strait Islander communities in Australia.
Hawaiʻi, 2023The University of Freiburg participated in the return of iwi kūpuna to Hawaiʻi. The repatriation took place in coordination with the State of Baden-Württemberg and representatives from Hawaiʻi.
Republic of the Marshall Islands, 2025The Universities of Göttingen and Freiburg returned deceased persons to a delegation of the Republic of the Marshall Islands.

In 2025, the Universities of Göttingen and Freiburg returned deceased persons to a delegation of the Republic of the Marshall Islands. The deceased persons in the care of the University of Freiburg came from Jaluit Atoll and had reached Germany through historical collecting and trading networks. The image shows the preparation for their formal handover and repatriation to their communities. Published with the permission of the Delegation of the Republic of the Marshall Islands.

Provenance Research on Destroyed Archives

Provenance research at the University of Freiburg is shaped by a severely fragmented archival situation. Large parts of the historical documentation were damaged or destroyed in the twentieth century. The surviving traces are dispersed across inventories, inscriptions, historical publications, institutional records and other indirect references.

For this reason, provenance cannot be reconstructed through a single archival source. It requires the careful connection of fragmentary evidence. The research distinguishes between what is documented, what is probable, what remains uncertain and what cannot currently be established.

Aim: Restitution and Repatriation

Visualisation of a relational provenance network for ancestral human remains. Colonial knowledge nodes (■) represent institutional archives and collections; community knowledge nodes (●) represent oral traditions, genealogical records, and repatriation programmes. Red lines mark cross-epistemic provenance hypotheses generated through a neural network layer. Dashed lines indicate latent connections or provenance gaps. Christoph Balzar, University of Freiburg, 2025.

Relational Provenance Reconstruction with Knowledge Graphs and Neural Networks

The University of Freiburg is developing methods of relational provenance reconstruction for cases in which archives are fragmented, destroyed or structurally incomplete. Provenance is understood as the reconstruction of relationships between people, places, events, documents, acquisition networks, contexts of violence, oral traditions, communal knowledge and histories of loss.

The research proceeds from two directions. From the archive, it connects surviving fragments, historical publications, inscriptions, colonial records, places, persons, events, institutions and documented contexts of violence. From communities and states of origin, it engages with oral traditions, communal knowledge, genealogical memory, place-based histories and histories of loss. Where these forms of knowledge meet, provenance hypotheses may emerge.

Neural networks and large language models support the evaluation of large and heterogeneous source collections. They can help identify references, patterns of colonial appropriation, connections between previously unlinked sources and systematic gaps in the transmission. The systems do not assign identities, origins or provenances. They generate possible connections that may inform provenance hypotheses. Every machine-supported hypothesis remains marked as a hypothesis and is subject to scholarly and ethical review.

Biographical Database and Archive Access

The following database is part of an ongoing transition. Earlier entries were created in archival and collection systems that documented the people in university custody as objects of an anatomical-anthropological collection. The University of Freiburg has begun to detach this responsibility holding from the object-centred archival logic and to transfer it into a biographical and relational form of documentation.

The aim is to describe these people not as collection objects, but to reconstruct their origins, relationships, contexts of violence and individual biographies as far as possible.

Because many historical entries are fragmentary, uncertain or shaped by colonial and racialising scientific practices, older terms, attributions or categories may still appear in the database as source or legacy data. These terms do not correspond to the present language and position of the University of Freiburg. They remain visible only where necessary for critical documentation, provenance research and the preparation of further repatriations.
