On the first floor of the Humboldt Forum, the Humboldt-Universität zu Berlin is designing an interdisciplinary stage for knowledge with the involvement of Berlin scientific institutions and the public. The Humboldt Lab has been conceived as an open, internationally networked laboratory. In keeping with the mindset of the brothers Alexander and Wilhelm von Humboldt, it will bring research, teaching and the public sphere together. The programme ranges from lectures, conferences and discussions about film screenings and exhibitions to forms of play and performances. It involves the design of experimental forms of knowledge acquisition, which include insights into history and into other cultures. This allows the Humboldt Laboratory to become a versatile platform and an important incentive for the development and presentation of the overarching themes that characterise the Humboldt Forum.
