Margarethe Meyer Schurz died in Washington, D.C., at the age of 43. The memorial tablet, dedicated in 1929, rests only a few feet from the site of the building where she ran her kindergarten -- the first ever in America.
In memory of Mrs. Carl Schurz (Margarethe Meyer Schurz) Aug. 27, 1833 -- March 15, 1876, who established on this site the first kindergarten in America, 1856.
The restored first kindergarten building was moved to the Octagon House grounds from its original site in downtown Watertown, corner of N. Second and Jones streets in December 1956, just 100 years after its founding in 1856 by Mrs. Carl Schurz. It was dedicated on September 15, 1957. The interior, a living room used as a classroom, is furnished in the period and portrays a kindergarten class in progress. is from http://froebel.50megs.com/images/schurz.html
And, Margarethe Schurz founded the first American kindergarten in Wisconsin in 1853. was at http://www.serve.com/shea/germusa/1848.htm
So, I will alter my guess to 1853???? But the reports vary from 1853 to 1857.
