Who invented the Spinning Jenny?

Question

In 1856, who invented the process whereby 5 tons of steel could be made in 30 minutes instead of in 50lb batches over 10 days and nights, at a tenth of the cost?

Answer 1

James Hargreaves

James Hargreaves was a weaver, carpenter and inventor in Lancashire, England. He was one of three inventors responsible for mechanising spinning. Hargreaves is credited with inventing the spinning jenny in 1764, Richard Arkwright patented the water frame in 1769, and Samuel Crompton combined the two creating the spinning mule a little later.
