The washing machine does not have a single clear inventor, but most modern sources credit James King with the first drum-based mechanical washing machine in 1851, and Alva J. Fisher with a pioneering early electric washing machine in the early 1900s.

Who “invented” the washing machine?

Because washing machines evolved over centuries, several inventors share credit, depending on what is meant by “washing machine.”

  • In 1767, Jacob Christian Schäffer built an early mechanical washing device.
  • In 1797, Nathaniel Briggs filed one of the first U.S. patents for a washing machine, though the details were later lost in a fire.
  • In 1851, James King patented a drum-style mechanical washer , often cited as the first machine that clearly resembles modern designs.
  • In 1901–1910, Alva J. Fisher ’s electric washer design (marketed as the “Thor”) helped popularize the electric washing machine in homes.

So when people ask “who invented the washing machine,” many historians answer: Schäffer for early concepts, King for the first drum machine, and Fisher for an important early electric model.

Inventor Year What they contributed
Jacob Christian Schäffer 1767 Designed an early mechanical washing device, often cited as the first recognizable “washing machine.”
Nathaniel Briggs 1797 Filed one of the earliest U.S. patents for a washing machine, though the patent description was later lost.
Henry Sidgier 1782 Patented a rotating drum washer in Britain, using a wooden barrel and crank.
James King 1851 Patented a drum-based mechanical washing machine, frequently named as the first machine similar to modern washers.
Hamilton Smith 1858 Patented a rotary washer that improved on King’s drum design.
Alva J. Fisher 1901–1910 Credited with a key early electric washing machine design (“Thor”), widely sold by the Hurley Machine Company.

Why there is confusion

Historians note that:

  • Laundry devices developed gradually from scrub boards and hand-cranked barrels to rotary drums and then electric motors.
  • Some older books simply label Fisher as the inventor of the electric washing machine , but later scholarly work shows other electric designs existed around the same time or earlier.
  • Because patents and early records were lost (like Briggs’s design in an 1836 Patent Office fire), it is impossible to give one definitive inventor for all washing machines.

In everyday usage, though, people often say “James King invented the first washing machine” (meaning the first drum-style mechanical washer) and “Alva J. Fisher invented an early electric washing machine.”

TL;DR:

  • Earliest machine-like device: Jacob Christian Schäffer (1767).
  • First notable drum-style machine: James King (1851).
  • Influential early electric model: Alva J. Fisher (“Thor,” early 1900s).
