The Chandos portrait is a famous painting believed to depict William Shakespeare, and is named after James Brydges, 1st Duke of Chandos, who owned the portrait. It has not been possible to solve the question of who painted the portrait or whether it really depicts Shakespeare. However, in 2006 the National Portrait Gallery in London concluded that the Chandos portrait was the most likely to be a representation of Shakespeare.

David Farragut was the first senior officer of the United States Navy during the American Civil War. He was the first rear admiral, vice admiral, and full admiral of the Navy. He is remembered in popular culture for his possibly apocryphal order at the Battle of Mobile Bay, usually paraphrased: "Damn the torpedoes, full speed ahead!" ("torpedo" was the contemporary term for what is now known as a naval mine).
