A sailor as well as a scholar, Morison garnered numerous literary prizes, military honors, and national awards from both foreign countries and United States, including the Presidential Medal of Freedom. Some of his textbooks continue to be widely used, though his treatment of American slavery in early editions was criticised as minimizing its brutality."
