Rupert, Prince Robert. Prince of Bavaria. Was born 1619. He was a son of Frederick V, Elector Palatine, by Elizabeth, eldest daughter of James I of England, and whose sister is known in English history as the Electress Sophia of Hanover. He took a prominent part in the civil wars of England under his uncle, Charles I, and was distinguished for his rash courage and impetuosity. In the reign of Charles II, he served in the fleet, and was afterwards appointed governor of Windsor. In his last years, he amused himself with scientific pursuits; and is said to have invented pinchbeck, sometimes called prince's metal, and the curious scientific toys called Prince Rupert's drops. He is buried in Henry VII's Chapel, Westminster. Died 1682.
