Horace Mann

Arguing that universal public education was the best way to turn unruly American children into disciplined, judicious republican citizens, Mann won widespread approval from modernizers, especially in the Whig Party, for building public schools. Most U.S. states adopted a version of the system Mann established in Massachusetts, especially the program for normal schools to train professional teachers. Educational historians credit Horace Mann, along with Henry Barnard and Catharine Beecher, as one of the major advocates of the Common School Movement. Provided by Wikipedia
