Volunteers CegeSoma

Our Volunteers

For several years, CegeSoma can count on the help of a dynamic and diverse team of volunteers. The majority of them works under the supervision of Fabrice Maerten, the member of staff responsible for the valorization of collections. 

Most of our volunteers do a precious work in the filing of documents and archives and in creating inventories of our collections (that mostly cover Belgian history between 1914 and the 1970s, with a focus on both World Wars). One of our volunteers is responsible for press clippings and files. Two young volunteers, from Germany and Austria, have joined our team and conduct several tasks for the reception of our public, for the archival section and for communication.

Our volunteers have access to a landscape office and can make use of the same basic infrastructures of our staff. They are obviously involved in the multiple activities of our centre. 

Do you have some spare time and do you have a keen interest in the careful filing of archives, press clippings and photographs, don't hesitate to contac Fabrice Maerten.

His arrival at CegeSoma within the framework of the data base project Wikibase Resistance can be seen as a continuation of the management of his own family archives about the Armée Secrète, of which some of his family were members. In parallel, he works for the cultural heritage promotion service of the municipality of Woluwé-Saint-Lambert.
