​INVENTIONS MADE BY WOMEN

10. Telecommunications Technology

 Some of the Telecommunication Technology developed by Dr Shirley Jackson include portable fax, touch tone telephone, solar cells, fibre optic cables, and the technology behind caller ID and call waiting.

11. The Dishwasher

 The Dishwasher was invented by Josephine Cochrane in 1887. Before her time, she even marketed her machine to hotel owners and even opened her own factory without the help of a man!

12. Wireless Transmission Technology

 Hedy Lamarr, a world famous film star, invented a secret communications system during World War II for radio-controlling torpedoes. This Technology also paved the way  for everything from Wi-Fi to GPS

13. Closed-Cercuit Television Security (CCTV)

 Marie Van Brittan Brown invented CCTV because of the slow response of police officers in 1969 to help people ensure their own security. This invention influenced modern CCTV systems used for home security and police work today.

14. The Modern Paper Bag

 Margaret Knight invented a machine that makes square bottomed paper bags in 1871. She almost didn’t get credit when Charles Anan tried to steal her work claiming that it wasn’t possible for a woman to create this brilliant invention.  (Margaret also invented a safety device for cotton mills when she was 12… that invention is still being used today)

15.  Central Heating

 Although Alice Parker’s invention in 1919 of a gas powered central heater was never manufactured. Her idea was the first that allowed for using natural gas to heat a home, inspiring the central heating systems used today

16.  Kevlar

 This life-saving material that is 5 times stronger than steel and used to make bulletproof vests was invented in 1965 by Stephanie Kwolek

17. Computer Software

 Dr Grace Murray Hopper was a computer scientist that invented COBOL which is the first user-friendly business computer software system in the 1940’s.  She was also a rear admiral in the U.S. navy and the first person to use the term “bug” in reference to a glitch in a computer system when she literally found a bug (moth) causing problems with her computer.
