The following is a book recommended to me by Hans Joachim Reincke:How Kindergarten Came to America by Baroness Bertha von Marenholtz-Bülow.

Book Description
Originally published as Reminiscences of Friedrich Froebel, this enchanting 1894 account of the German inventor of kindergartens was instrumental in bringing kindergartens to the United States. This lively portrait of a pioneer of modern education is a refreshing reminder of the essential role of play and creative exploration in the development of children. Froebel's methods provide a much-needed antidote to the current emphasis on high-stakes testing and accelerated curricula—a corruption, as Herbert Kohl argues in his foreword, of the original concept of kindergartens as children's gardens of learning.

About the Authors
Baroness Bertha von Marenholtz-Bülow (1810-1893) befriended Friedrich Froebel in the last years of his life and helped to establish kindergartens throughout Western Europe. Mary Peabody Mann (1806-1887), the wife of Horace Mann, was an educator, writer, and leader of the kindergarten movement in the United States. Herbert Kohl is the National Book Award-winning author of more than forty books. He lives in San Francisco.

The ironic thing is that Kindergarten has virtually disappeared from the German educational landscape, and the kindergartens in the U.S. would be virtually unrecognizable to Froebel... unless he were to visit Clear Spring School.
