Like much else in the game, the idea of duplicate play was invented for whist. At "whist drives" North/South pairs sat in the same positions throughout, East/West pairs moved up the series of tables and boards moved down. This simple movement was invented in the 19th century. The first game of duplicate whist was organised by "Cavendish" in London 1857, but it was not followed up. It was played in Chicago in 1880, and the first book about it was written in 1891 by John T. Mitchell. His simple method is known as the Mitchell movement.
