Dishwasher - 1886
U.S. Patent No. 355, 139
Josephine Cochran, frustrated by the time it took to wash dishes after entertaining and the amount of dishes that were broken during washing, built a machine that would do both. She founded a company to manufacture her dishwasher, which eventually became KitchenAid®.
Windshield Wipers - 1903
U.S. Patent No. 743,801
Mary Anderson's invention was apparently conceived during a trip to New York City as she watched streetcar drivers opening the windows of their cars when it rained so that they could see. When she returned home to Alabama, she devised a swinging arm device with a blade made from rubber that could be controlled with a lever from within the vehicle.
Waterproof Diaper Cover - 1951
U.S. Patent No. 2,556,800
Marion Donovan first invented a diaper cover after getting tired of the cloth diapers leaking after her children’s naps. She next turned to a diaper solution that would do away with the need to do so much laundry – what we know today as disposable diapers.
Marie Van Brittan Brown
Home Security System - 1969
U.S. Patent No. 3,482,037

U.S. Patent No. 3,819,587
Stephanie Kwolek’s invention was born out of an assignment from her employer, DuPont, to find the next generation of fibers that could withstand extreme conditions for use in tires.

Propulsion System - 1974
U.S. Patent No. 3,807,657
Yvonne Brill’s propulsion system helps keep communication satellites from slipping out of their orbits and remains the industry standard for unmanned spacecraft.

Self-Cleaning House - 1984
