The first cash register was invented by James Ritty following the American Civil War. He was the owner of a saloon in Ohio, and wanted to stop employees from pilfering his profits. He invented the Ritty Model I in 1879 after seeing a tool that counted the revolutions of the propeller on a steamship. With the help of John Ritty, his brother, he patented it in 1883. | |
