The 1-cent Famous American Educators stamp, issued March 14, 1940, features Horace Mann (1796-1859). Attracted to politics in his youth, Mann soon focused on improvement of education in America. His belief that every citizen had a right to be educated led him to campaign for universal public education. His political connections enabled him to establish a sound public school system in his native Massachusetts. His works and writings became nationally known and influenced educational development across America.
