The Spinning Jenny was invented in 1764 by James Hargreaves in Stanhill, Oswaldtwistle, Lancashire in England. It was invented by accident, James Hargreaves worked in a thread making business with his family. James Hargreaves was making thread one day when his daughter knocked the spinning wheel over! Luckily it didn’t break and it kept moving! James was fascinated by that so, he called his new invention The Spinning Jenny. The spinning jenny was improved to spin 8 times more thread than the spinning wheel! This is very important because thread is used to make clothes and blankets.
