The Fondation Jeunes Scientifiques Luxembourg (FJSL) is an organisation with public utility that promotes natural and social sciences among young people in Luxembourg and provides a platform where they can exhibit their own scientific projects, participate in cultural exchanges and win prestigious awards. The foundation was first established under the form of an association in 1977 and a separate foundation in 1992 to assure a steady financing of the association’s activities. On a national level, FJSL is closely working with the Service National de la Jeunesse, with the Ministère de l’Education nationale, the Mérite Jeunesse, the University of Luxembourg, the Musée national d’histoire naturelle and many educational institutions (national and international alike). On an international level, FJSL is a founding member of MILSET (Mouvement International pour le Loisir Scientifique et Technique) and its contest is recognised by the UNESCO. As of 2017, FJSl has been awarded the High Patronage of his Royal Highness the Grand-Duc. The FJSL organises each year the national "Jonk Fuerscher" contest, which targets young people who are interested in science and eager to create their own projects. The contest is a great opportunity for the participants to get in contact with the scientific world, meet like-minded people, present their own projects in front of a jury and an audience and win many prestigious prizes. In addition, the FJSL has initiated the Expo-Sciences Luxembourg in 2009. The Expo-Sciences is an international, non-competitive science fair that welcomes young laureates from all over the world. Young scientists get the possibility to present their scientific projects alongside our national participants. The Expo furthers international relationships, the exchange of ideas and cultures and is an excellent opportunity to visit Luxembourg and learn more about the Grand-Duchy.
