Renilde Montessori, Hilla Patell and Camillo Grazzini organised the first EsF Assembly. It was held at the Villa Montesca in Citta di Castello, Italy, where in 1909 Maria Montessori had conducted her first training course. The assembly was a six week intense study and reflection. It resulted in the formalisation of Educateurs sans Frontières as a part of AMI.
