Walter verwendet nicht den Begriff „Kritische Erziehungswissenschaft“ bzw. dessen englisches Pendant „Critical pedagogy“, sondern „social reconstructionism“. Walters Originaltext: „Manumit was described by its supporters as representing an alliance of progressive labor and progressive education. The school was rooted in the traditions and practices of progressive education and workers' education. Manumit shared several characteristics with other Progressive-era alternative schools, but was distinguished by the open alliance with the labor movement and by its early commitment to what was later referred to as social reconstructionism.“ Scott Walter: Labor's Demonstration School: The Manumit School for Workers' Children, 1924-1932. Bei Walters Text handelt es sich um ein Paper für ein Meeting der „History of Education Society (Chicago, 1998)“
Über das Progressive School Committee for Refugees' Children sind über das Buch von Warburg Spinelli hinaus nur sehr wenige Informationen zu finden. Ausführlich informiert die Webseite Unknown Story Of American Rescues Of Children Of The Holocaust über die Arbeit der German Jewish Children’s Aid.
Brief Chronology of Manumit School: „Progressive Schools’ Committee for Refugee Children formed under leadership of Mildred and William Fincke. At least 23 Jewish refugee children attended Manumit. (See: Time Magazine, 3/27/1939). […] Manumit ‚contacts with European underground and resistance groups, and with Jewish groups, both dating back to 1935, later contacts with British groups (during the blitz of 1940) greatly enriched the enrollment with interesting evacuee children‘.“
Labor Temple: „Labor Temple was founded in 1910 by the Rev. Charles L. Stelze of the Presbyterian Home Mission Board. The first Labor Temple occupied the former Fourteenth Street Presbyterian Church, located at 225 Second Avenue near Union Square, and built in 1851. Under Stelze's leadership, Labor Temple would be‚ entirely unsectarian, where every man, if he have a message, may give it expression, and if it be good it will receive attention.‘ On its opening day, Labor Temple was attended by five hundred members of labor unions, Socialist, Anarchists, and persons who took interest in labor matters and sociologists.“
