Friedrich Froebel was a German educator who established kindergarten in the early 19th century based on his philosophy of education. He believed that play was essential to children's learning and development. Through his gifts and occupations used in kindergarten, he aimed to promote children's self-directed learning and socialization. Froebel's ideas became widely adopted and kindergartens were established across Europe and North America by the late 19th century. Modern early childhood education continues to be influenced by Froebel's emphasis on play and developing the whole child.
