A Famous Woman
There are certain things in life that we as humans take for granted.
I want to point out one in particular .Occasionally, while driving during the winter months it could rain or snow. Immediately we either flip a switch or move a lever
that operates our windshield wiper arms.. This device improves the drivers visibility.
However, we never give a thought as to who was behind this idea. Mary Anderson applied for and received a patent for a manual windshield wiper arm in 1903. While riding on a streetcar
in New York Mary observed the conductor had to opened the window in
order to see during the rain. Mary designed an arm that would swing with a rubber
blade.This manual device became standard in 1916. The automatic version would come a year later. Charlotte Brigwood received a patent and manufactured the automatic version. Unfortunately, for Charlotte it was not a commercial success. These two women are responsible for the device that improves the visibility on those days when it rains or snows.
