One hundred years after the foundation of Bauhaus , the famous German school of architecture, arts and design (1919-2019), Museion presents the "Lichtspiel-Apparat" (machine for colored light shows) by the artist Ludwig Hirschfeld-Mack (1893-1965) . The work, created between 1923 and 1925, is one of the first ever to combine electric light and movement.

The one presented at Museion is an authorized replica of the machine - the original was in fact lost in the 1930s. The exhibited specimen is part of the Museion Collection and was reconstructed on the occasion of the first major exhibition at Museion in 2000 on Ludwig Hirschfeld-Mack's work "Reflektorische Lichtspiele" - the exhibition was also presented at the Jewish museums in Vienna and of Frankfurt. The new exhibition at Museion, which has a purely documentary character, is completed by photographs, construction plans, scores, historical and recent films, which illustrate the complex functioning of the machine, but also its history. The staging of the exhibition, which makes use of color and birch wood panels, was created for the occasion, taking inspiration from the Lichtspiel-Apparat and documents relating to its operation.
