Stephen E. AmbroseStephen Edward Ambrose (January 10, 1936 – October 13, 2002) was an American historian and biographer of U.S. Presidents Dwight D. Eisenhower and Richard Nixon. He was a longtime professor of history at the University of New Orleans and the author of many bestselling volumes of American popular history.
There have been allegations of plagiarism and inaccuracies in his writings. However, in a review of ''To America: Personal Reflections of an Historian'' for the ''New York Times'', William Everdell wrote that "he certainly deserved better from some of his envious peers" and credited the historian with reaching "an important lay audience without endorsing its every prejudice or sacrificing the profession's standards of scholarship."
