who invented washing machine

The washing machine was first invented by a German scientist named Jacob Christian Schäffer in 1767. He is credited with creating one of the earliest prototypes of the washing machine. Later, in 1797, an American named Nathaniel Briggs obtained the first patent for a washing machine. The first drum-based washing machine patent was filed by James King in 1851. The first electric washing machine is generally attributed to Alva John Fisher, who invented the "Thor" in 1908, which was the first electric-powered washing machine to go on the market.
