Kindergartens in the US

As a grad student in my home state, I was already somewhat involved with the University of Wisconsin because of the little book by Campbell and Stanley called "Experimental and Quasi-experimental Designs for Research".  Because of that and other contacts, I chose to look for teaching jobs at the U. of W. When Lynn went to grad school, we had been living in Wisconsin so she gravitated to the U. of W. for PhD studies.

The other day, when I was blogging about my history, I wanted to cite some of the things I had read and heard about Wisconsin higher learning.  A friend who is a lifelong admirer of the Peabody family of Boston felt that I had wrongly credited Wisconsin with having the first kindergarten in the US.  We did some scrambling and decided that the Peabodies had the first English-speaking kindergarten and the one in Wisconsin was the first German-speaking kindergarten.
