In 1997, Jaap van Zweden and his wife Aaltje established the Papageno Foundation, the objective being to support families of children with autism. Now, over 20 years later, the Foundation has grown into a multi-faceted organisation which, through various initiatives and activities, focuses on the development of children and young adults with autism. The Foundation provides in-home music therapy to children through a national network of qualified music therapists in the Netherlands; opened the Papageno House in August 2015 (with Her Majesty Queen Maxima in attendance) for young adults with autism to live, work and participate in the community; created a research centre at the Papageno House for early diagnosis and treatment of autism and for analysing the effects of music therapy on autism; develops funding opportunities to support autism programmes; and launched the app, TEAMPapageno, which allows children with autism to communicate with each other through music composition.
