Abstract
The purpose of this thesis is not merely to relate the life-story and the achievements of a comparatively little- known educator, but to show that he was, in truth, a pioneer of modern pedagogy, that he foreshadowed, in the France of over two centuries ago, the educational reformers in the England and the New World of today.|That he was an innovator in many an educational sense was discovered by a study of his biographers, sectarian and non-sectarian. This great master of pedagogy "crystallized into its final form" that famous Simultaneous Method, already used in some shape in the Jesuit Schools and organized by several others of his predecessors, who were trying to correct the evil of enormous waste of time, of disorder and loss of efficiency, resulting from the individual method of instruction then in use.
