This study sheds new light on childhood education, and reveals Giuseppina Pizzigoni as a contemporary educator of Maria Montessori. While the former is almost unknown and the latter enjoys worldwide fame, both were protagonists of the profound changes in the Italian school system in the 20th century. Their lives developed in parallel, and both great women loved school, respected children, and believed in the strength of education. Pizzigoni's disciple Sara Bertuzzi later picked up the baton, and continued the impulse of innovation, freedom, inclusion and sustainability, faithful to the features and fundaments of Pizzigoni's pedagogy and methodology. She became the only expert in the field of the new school, and her diaries highlight the theory and practice of the experimental method in both kindergarten and preschool.
