A closely examined biography of an educator, Lawrence-Lowell descended, whose long lines of distinguished New England-Boston, industry plus philanthropy background contributed to his outstanding success in collegiate reforms. It is too a partial history of the 20th century, of Harvard University and his contributions in modifying the elective system of the undergraduate college, of instituting general examinations in a BA major, of sponsoring the tutorial system for upper classmen, of inaugurating the house plan for a greater collegiate unity, of his stands- and standards- for academic freedom, in guiding the physical growth of Harvard, in championing the League of Nations. This many dimensioned, understanding portrait poses a democratic aristocrat against the period of educational changes and reforms, and is of particular pedagogical, Boston and Harvard interest.
