All of these inventions were created by women!
The bulletproof vest was invented by Stephanie Kwolek in 1966. Kwolek was a chemist who worked for DuPont and discovered a liquid polymer that was stronger and more durable than steel. This polymer was used to create Kevlar, the material used in bulletproof vests.
The fire escape was invented by Anna Connelly in 1887. Connelly was concerned about the safety of tenement dwellers in New York City and wanted to find a way to help people escape from burning buildings. She designed the first fire escape that could be used by multiple people at the same time.
The windshield wiper was invented by Mary Anderson in 1903. Anderson was visiting New York City when she noticed that streetcar drivers had to stop their cars to wipe snow and rain off their windshields. Anderson designed a device with a rubber blade that could be operated from inside the car, allowing drivers to clear their windshields without stopping.
The laser printer was invented by Gary Starkweather in 1969, but the technology behind it was actually based on the work of three women: Marion Donovan, Jean Sammet, and Grace Hopper. Donovan invented the disposable diaper, which used a moisture-resistant material that Starkweather adapted for use in the laser printer. Sammet and Hopper developed early programming languages, which were essential to the operation of the printer.
Overall, these inventions demonstrate the significant contributions that women have made to science and technology. Despite facing significant discrimination and barriers throughout history, women have been responsible for shaping the world we live in today.
