Martin and Sophie Keizer Waterman family collection
The collection consists of a flashlight, documents, and photographs relating to the experiences of Meijer and Sophia Frederika Keizer Waterman, their daughter, Roosje, and other family members in the United Kingdom, the Netherlands and the Westerbork transit camp, and the Vittel internment camp in France before, during, and after the Holocaust. Some of these materials may be combined into a single collection in the future.
