America's First Kindergarten

The first kindergarten in the United States was established in Watertown, Wisconsin in 1856 by Margarethe Schurz, a German immigrant who had studied under Friedrich Froebel, the German educator who invented the kindergarten concept. Schurz opened the school in her home and conducted classes in German for the children of German immigrants in her community. When she met educator Elizabeth Peabody in Boston in 1859 and described her school, Peabody was inspired to open the first English-language kindergarten in the United States in 1860.
