She was named by Eleanor Roosevelt one of the ten most influential women in the United States. Dorothy Canfield brought the Montessori method of child rearing to the United States, presided over the country's first adult education program, and shaped literary tastes by serving as a member of the Book-of-the-Month Club selection committee from 1925 to 1951.
