These photos from the archives of the Forward Newspaper, founded in 1897, stem from an ad placed in the paper in 1935:
'The Workmen's Circle of New York, beneficial support system and friend to Jewish immigrants and progressive citizens everywhere, extended an invitation to family, friends, members and children to come Upstate and enjoy the opening of their 10th season at Camp Kinder Ring in shady, cool, gloriously nature-bound Pawling, New York. A rich program was on offer with concerts, symposiums and atheltic games--all prepared by the talented personnel.'
The camp, whose alumns include noted former US Senator Barbara Boxer, offered a vibrant progressive Jewish summer education for campers, primarily the children of the immigrant working classes, that was steeped in Yiddish language and culture. The camp still exists, currently located in Sylvan Lake, NY.
