In 1843, Nancy M. Johnson invented the first ice cream maker with a crank on the outside of the wooden tub. The crank mixes the ice cream, while also scraping the frozen ice cream off of the sides of the pot. Before 1843, making ice cream required more time. The crank on the outside of the wooden tub eliminates the step of removing the pot from the wooden tub to scrape the sides of the pot of frozen ice cream. After the creation of Nancy Johnson’s invention, commercial ice cream companies started to use ice cream makers powered by “horse-powered treadmills, steam engines, and finally electric motors”. People who made ice cream at home began using electric ice cream makers as well. Ice cream production was more popular when sugar became cheaper and ice was easier to obtain. After the Civil War ended, ice cream prices had decreased, and more wholesalers had joined the ice cream making business.
