Margarethe Schurz
Margarethe Schurz can be credited for expanding Froebel's beliefs and bringing his idea of Kindergarten to the United States. In 1856, she used what she'd learned in Germany about Froebel's principles to open the first Kindergarten in Watertown, WI- the first Kindergarten in the United States! However, the German language was still used at Schurz's Kindergarten, pictured below.
