Whose invention was the windshield wiper?

The first practical windshield wiper is credited to Mary Anderson of Alabama, in the United States. On a visit to New York City in the winter of 1902, she watched a streetcar driver repeatedly open his window and lean out to clear snow and sleet from the glass so he could see. Back home she designed a lever inside the vehicle that swept a rubber blade across the windscreen, and she received a patent for it in 1903. Her idea arrived before cars were common, and her patent expired before it ever made her any money. Later inventors added automatic and electric versions, among them Charlotte Bridgwood, who patented an electric wiper in 1917, but Anderson's hand-operated device is widely regarded as the original.
