Henry Knox (1750 - 1806) attended the Boston Latin School, but his success was from self-taught skills. He owned a bookstore and read extensively on military history, strategy and tactics. During the British Army's siege of Boston, Knox applied his self-taught knowledge as an artillery commander in America's Continental Army. Knox first met George Washington during the 1775 siege of Boston, when Knox epically brought artillery captured at Fort Ticonderoga all the way to Boston. This act solidified Knox's status with his commander in chief. Later, Knox joined Washington's presidential cabinet as Secretary of War.
