Windshield
wipers have been used on cars since they were first invented by Mary
Anderson in 1903 and were standard equipment on most makes by 1916. The
first automatic wiper powered by an electric motor was invented by
Charlotte Bridgewood in 1917. Little did either realize what their
inventions would become on today's production car.
All cars from that time until the Forties and even the Fifties had a
flat windshield and the wiper blade need be only a rubber squeegee
mounted to a rigid frame that could wipe across the flat glass. They
were attached to an extension arm by a small bolt and nut or a hooking
mechanism that allowed for a small amount of flexibility at the joint.
The blades themselves were very short, in most cases less than 15 inches
long.
