# 1. Computer programming language and Computer compiler
Admiral Dr. Grace Murray Hopper developed the first computer compiler and the first computer programming language which helped revolutionize the world of computers. Compilers are very important to programmers, because any improvement to a compiler leads to a large number of improved executable programs. Dr. Hopper also popularized the idea of machine-independent programming languages, which led to the development of COBOL, one of the first modern programming languages. She also coined the term "bug" for a computer problem, and co-developed COBOL, the first user-friendly business computer software program.
As a woman inventor, she won numerous awards, including the National Medal of Technology in 1991. Dr. Hopper also had received honorary degrees from 30 universities. This is why she is known as the "mother of computers".
# 2. Car windshield wiper
In the early 1900s, drivers had to stop every few blocks to wipe the windshields of the cars when it was raining or snowing. Mary Anderson observed this problem and saw it as an opportunity. In 1903 she put together a squeegee (blade with rubber edge) and a spindle and then attached it to a handle inside the car. To clear the windshield, the driver simply pulled down on a handle.
People were initially doubtful of Anderson's invention, fearing that it may distract drivers, but within 10 years after she patented the device, almost every car used her invention. It was also a woman inventor, Charlotte Bridgwood, who in 1917 first patented the automatic windshield wiper that we use today.
# 3. Disposable Diapers
Marion Donovan developed the first waterproof baby diaper. It was a waterproof baby diaper cover that prevented diaper rash and it also introduced the use of plastic snaps as opposed to safety pins. At first, she was unsuccessful in selling this invention to manufacturers. But she was persistent and persevered on her own. Later her company and patents were sold for $1,000,000
Marion Donovan also developed and patented other women-related convenience items such as: facial tissue box, storage container box, towel dispenser, hosiery clamp, closet organizer, and dental flossing products
# 4. Bullet Proof Vests
American chemist Stephanie Kwolek invented poly-paraphenylene terephthalamide or better known as Kevlar, a tough durable material now used to make bulletproof vests.
While working for DuPont in 1964, in anticipation of a gasoline shortage, her group began searching for a lightweight yet strong fiber to be used in tires. And during this time, she was surprised to discover a new fiber that would not break when nylon typically would. Not only was it stronger than nylon; Kevlar was ounce for ounce five times stronger than steel. Kevlar is also now used for making suspension bridge cables, helmets, brake pads, skis, and camping gear.
# 5. Fire Escape
Because of Anna Connelly, who patented the first fire escape in 1887, many people trapped inside apartment or building fires are alive. Though other fire escapes had been invented before, her invention was the basis for modern fire escapes because it had an exterior staircase.
