Samuel Adams [SEP] Legacy
Samuel Adams is a controversial figure in American history. Disagreement about his significance and reputation began before his death and continues to the present. Adams's contemporaries, both friends and foes, regarded him as one of the foremost leaders of the American Revolution. Thomas Jefferson, for example, characterized Adams as "truly the "Man of the Revolution"." Leaders in other colonies were compared to him; Cornelius Harnett was called the "Samuel Adams of North Carolina", Charles Thomson the "Samuel Adams of Philadelphia", and Christopher Gadsden the "Sam Adams of the South". When John Adams traveled to France during the Revolution, he had to explain that he was not Samuel, "the famous Adams".
