My great grandfather

Interesting that my first job was as a Montessori preschool teacher.  And it turns out that my great grandfather was a very early Waldorf educator in Switzerland (which is very similar).

Willi Aeppli (1894–1972) was a master Waldorf teacher in the Rudolf Steiner School in Basel, Switzerland. He is remembered as an excellent teacher who used his observations and daily experience to enrich his classroom teaching. He also led many informal courses on the art of education for teachers and prospective teachers throughout his long career as an educator."
