Robert W. Johanssen, "Douglas, Stephen Arnold," American National Biography Online, February 2000, http://www.anb.org/articles/04/04-00325.html.
The experience not only aroused his ambition for a career in politics but also stimulated his interest in an education. In 1830 he moved with his family to upstate New York where he entered Canandaigua Academy, studying the Latin and Greek classics, mathematics, and English literature. Canandaigua was a cultural center of swirling ferment and unrest. The recently completed Erie Canal had opened the region to economic development, and the area was alive with a spirit of reform and change that Douglas could neither ignore nor resist.
