Abraham Lincoln (allthetropes.org) That guy who won the American Civil War, proclaimed the slaves free, delivered the Gettysburg Address and was shot dead at the theatre. He’s also known for wearing a top hat and being very tall (the tallest president, in fact, at six feet four inches), and when he for a brief time took direct control of the Union army, showed himself to be a talented military strategist as well. A genial and charming speaker, Lincoln had an uncanny ability to explain complex issues in layman’s terms, and his speeches are among the most famous in American history. Considered an untested and possibly radical figure, he is famous for Growing the Beard in office. In many ways he’s the only post-Founding Fathers/ pre-Teddy Roosevelt President who’s thought of at all. He is almost universally considered to be one of the greatest (if not the greatest) Presidents in American history.
