Inventions & Profiles for the Month of July 2020- Invention of the windshield wiper(Mary Elizabeth Anderson)
Mary Elizabeth Anderson (February 19, 1866 – June 27, 1953)[1] was an American real estate developer, rancher, viticulturist and inventor of the windshield wiper blade. On November 10, 1903 Anderson was granted her first patent for an automatic car window cleaning device controlled from inside the car, called the windshield wiper.
Mary Anderson was born in Greene County, Alabama, at the start of Reconstruction in 1866. In 1889 she moved with her widowed mother and sister to the booming town of Birmingham, Alabama. She built the Fairmont Apartments on Highland Avenue soon after settling in. By 1893, Mary Anderson had moved west to Fresno, California until 1898 where she then operated a cattle ranch and vineyard.
In a visit to New York City in the winter of 1903, in a trolley car on a frosty day, Anderson observed that a trolley car driver struggled to see past the windows because of the falling sleet. When she returned to Alabama she hired a designer for a hand-operated device to keep a windshield clear and had a local company produce a working model. She applied for, and in 1903 was granted, a 17-year patent for a windshield wiper.Her device consisted of a lever inside the vehicle that controlled a rubber blade on the outside of the windshield. The lever could be operated to cause the spring-loaded arm to move back and forth across the windshield. A counterweight was used to ensure contact between the wiper and the window. Similar devices had been made earlier, but Anderson's was the first to be effective.
In 1905 Anderson tried to sell the rights to her invention through a noted Canadian firm, but they rejected her application saying "we do not consider it to be of such commercial value as would warrant our undertaking its sale." After the patent expired in 1920 and the automobile manufacturing business grew exponentially, windshield wipers using Anderson's basic design became standard equipment.[citation needed] In 1922, Cadillac became the first car manufacturer to adopt them as standard equipment.
Anderson resided in Birmingham, where she continued to manage the Fairmont Apartments until her death at the age of 87. At the time of her death she was the oldest member of South Highland Presbyterian Church. She died at her summer home in Monteagle, Tennessee. Her funeral was conducted by Dr. Frank A Mathes at South Highland and she was buried at Elmwood Cemetery.
