Maria Montessori. The 1946 London course was the first course given in Europe by Maria Montessori after she and her son Mario returned from seven years of exile in India. This course was to have significant pedagogical consequences, since ‘The 1946 London Lectures’ became the foundation of AMI’s 3 – 6 courses. • The Montessori Series: 264 pp, soft cover, 2012 edition, Volume 17.
