John Bingham, 7th Earl of Lucan

Richard John Bingham, 7th Earl of Lucan, commonly known as Lord Lucan, was a British peer and gambler who vanished in 1974 after being suspected of killing Sandra Rivett and attempting to murder his wife. An evacuee during World War II, Lucan attended Eton College and served with the Coldstream Guards in West Germany from 1953 to 1955. Having developed a taste for gambling, he played backgammon and bridge, and was an early member of the exclusive group of wealthy British gamblers at the Clermont Club. Lucan's losses often exceeded his winnings, yet he left his job at a London-based merchant bank and became a professional gambler. He was known as Lord Bingham from April 1949 until January 1964.
