Willis Johnson's invention of the hand-cranking rotary egg beater in 1884 transformed home baking, allowing for easy aeration of eggs and batters. The device, which functioned through a cranked handle spinning two beaters, gained popularity and sales during its time. Despite the introduction of electric mixers in 1908, it took decades for them to become mainstream in domestic kitchens. The rotary beater established a foundation for modern mixing technology, highlighting its pivotal role in the evolution of baking tools.
Willis Johnson patented a game-changing solution: hand-cranking rotary egg beaters. This invention changed at-home baking for good and was registered in 1884.
The rotary beater functioned by cranking a handle that spun a wheel, whizzing two beaters at unmatched speed and precision to aerate mixtures.
Surviving pamphlets and newspaper cuttings rave about sales of the rotary beater; it was clearly the technology of the moment.
While an electric mixer was patented in 1908, it took another 20 years for this upgraded technology to really take hold in homes.
