Clarence W. Gleason was a longtime teacher of Greek and Latin in Massachusetts private secondary schools and the author or editor of numerous textbooks, who earned a degree of respect from his colleagues and devotion from his students over five decades that was commensurate with his span of service. His teaching skills, his passion for ancient literature, and his benign but demanding attention to individual pupils provided a model which induced many of them to follow academic and scholarly careers in classics.
