The 16th President of the United States. Born in a log cabin in Hodgenville, Kentucky in 1809. Served as President during the Civil War. Issued the Emancipation Proclamation. Delivered the Gettysburg Address. Killed in 1865 by an assassin named John Wilkes Booth in Ford's Theater in Washington, D.C.. Remembered for his beard, dry wit and stovepipe hat. Made guest appearances in "Star Trek" and "Bill and Ted's Excellent Adventure" (and, MALTP reminds me, "Happy Gilmore").

Surely one of America's most revered Presidents. There are people who dislike him intensely -- their complaints about ol' Honest Abe tend to boil down to "Hey! He let the slaves go! I wanted slaves, dammit!"
