Grant is a 2017 biography of Ulysses S. Grant, the 18th President of the United States, written by American historian and biographer Ron Chernow. Grant, a Union general during the Civil War, served two terms as president, from 1869 to 1877. Chernow asserts that both Grant's command of the Overland campaign and his presidency have been seen in an undeservedly negative light. Source: Wikipedia (en)
