Under the museum's first director, the geologist Herman van Cappelle, the collection policy moved towards natural history and ethnology.
Around 1910 the museum was also the first organisation in The Netherlands that programmed educational movies, an initiative that led to the foundation of the first school cinema in the country.
The museum moved several times, until the municipality had its present building built in 1985, by the design by architect WG Quist.
Museon aims at transferring knowledge about man and his relation with nature and culture and provides easily accessible information about topical themes and developments in science and society.
