The person most credited with founding American public schooling, Massachusetts educator Horace Mann, also linked public education to democracy. “A republican form of government, without intelligence in the people,” he wrote, “must be, on a vast scale, what a mad-house, without superintendent or keepers, would be on a small one.” Mann believed it important that public schools educate all children together, “in common.” The mix of ethnicities, races, and social classes in the same schools would help children learn the habits and attitudes of citizenship.
