In February 2021, a team at the Centre for Contemporary and Digital History at the University of Luxembourg launched a call for contributions as part of the project, “WARLUX – War Experiences in Luxembourg,” funded by the Luxembourgish Research Fund (Fond National de la Recherche). The team researches the personal side of the Luxembourgish war generation’s history. To uncover the individual experiences of these men, women and families, the team asked the public to share their family stories, letters, diaries, photographs, and other personal documents. The researchers aimed to enrich existing records of individual experiences, which had not yet been collected or published. While the crowdsourcing campaign was intended as complementary research material, we created a unique digital archive of personal memories and individual voices in the form of first-hand documents, a novelty in the cultural landscape in the Grand-Duchy of Luxembourg.
