Explanation:

Mary Anderson travelled to New York City during the first years of the twentieth century, and while rifdng a trolley on the street, she noticed that the driver had to pull over and clean the snow and do everything with his hands. When she returned to Birmingham she started creating a device similar to a windshield, that had to be operated with a lever from inside the vehicle. Then she had her design produced and obtain the patent on November 10, 1903. Her first attempt to sell her design was with a Canadian company, in 1905, but the firm saw no potential value in the design.
