Maria Montessori
Netherlands (1917–1936)

In 1917, Montessori lectured in Amsterdam, and the Netherlands Montessori Society was founded. She returned in 1920 to give a series of lectures at the University of Amsterdam. Montessori programs flourished in the Netherlands, and by the mid-1930s there were more than 200 Montessori schools in the country. In 1935 the headquarters of the Association Montessori Internationale, or AMI, moved permanently to Amsterdam.
