Looking at the development of early childhood education, there are two western early childhood education masters who have had the most important influence on the development of western early childhood education and even the development of the whole world: one is the founder of kindergarten-/kloc-the German early childhood educator Volper in the 9th century, and the other is the founder of Children's Home-the Italian early childhood educator Montessori in the 20th century.

As the founder of kindergarten, Flepp is the founder of modern western preschool education theory.

He issued the call of "Let's live with children", founded the first kindergarten in the world, built a complete theoretical system of kindergarten education, and devoted himself to kindergarten education all his life.
