This booklet sketches the life, educational theories, and accomplishments of Albert F. Ames (1888-1931). Ames was trained as a mathematician, and served six years as a mathematics teacher in Canada before becoming superintendent of schools in Riverside, Illinois. He co-authored five mathematics textbooks with J. A. McLellan. These texts, revolutionary in their time, were based on theories developed by Dewey and McLellan and shared by Ames. (SD)
