This article features the life and accomplishments of Horace Jeremiah Voorhis in the field of progressive education. Voorhis earned the first Master of Arts degree in Education awarded by the Claremont Graduate Schools after he submitted his master's thesis, "The Education of the Institution Boy: A General Outline of Policies for the Voorhis School for Boys." Far more than the policy manual implied by the title, the thesis outlined Voorhis' thinking on the relationship between education, religion, and social reconstruction and constituted a blueprint for the development of a remarkable school. Voorhis' plan called for a confluence of progressive educational methods, political theory, and religious instruction to train a cadre of boys as the vanguard of a new social order. For ten years, from 1928 to 1938, Voorhis' vision took shape as a residential school for orphaned boys in San Dimas, California. Voorhis was just the kind of secular missionary described by Robert Crunden, and his educational experiment stands as an example of the deep idealism that motivated many progressive educators.
