April 1979 saw the opening of the Museum of Music Automatons. To mark its 40th anniversary, the museum is presenting four themes: Music automatons with figures, music boxes, musical souvenirs and Swiss railway station and waiting hall music boxes. They offer a retrospective of forty years of collecting. The name of the anniversary exhibition – by analogy with “Industry 4.0” (i.e. the fourth industrial revolution) – suggests that some content in the museum will be presented via new media, not least in the newly designed ballroom, due to reopen in autumn 2019.
