The earliest washing "machine" was the scrub board, or wash board, invented in 1797. American James King patented the first washing machine to use a drum in 1851 -- the drum made King's machine resemble a modern machine; however, it was still hand-powered.
In 1874, William Blackstone of Indiana built a birthday present for his wife. It was a machine which removed and washed away dirt from clothes. This was the first washing machine designed for convenient use in the home.
