Kindergarten schools owe their concept to A) Froebel.
Kindergarten, meaning "children's garden" in German, was introduced by Friedrich Froebel in the early 19th century. Froebel was a German educator and is widely regarded as the founder of the modern kindergarten system. He emphasized play-based learning, self-activity, and the importance of nurturing a child's natural curiosity and creativity. Froebel's ideas and methods greatly influenced early childhood education and laid the foundation for the establishment of kindergarten schools worldwide.
