Inventions by WOMEN

1. The Computer Algorithm – Ada Lovelace is essentially the first computer programmer due to her work with Charles Babbage at the University of London in 1842. In fact her notes were an essential key to helping Alan Turing’s work on the first modern computers in the 1940s.

2. The Ice Cream Maker – was invented by a woman named Nancy Johnson in 1843. Her patented design is still used today!

3. 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.

4. The Life Raft – this life saving craft was invented by Maria Beasley in 1882 who also invented a machine that makes barrels.

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

6. The Fire Escape was invented by Anna Connelly in 1887.

7. The Car Heater – we all owe our thanks to Margaret A Wilcox who invented the car heater in 1893, she also invented a combined clothes and dishwasher.

8. an improved Medical Syringe – an improved rectal syringe which allowed one-handed application was invented by a woman by the name of Letitia Geer in 1899.

9. Monopoly – this popular board game was designed by Elizabeth Magie in 1904, originally called the Landlord’s Game. The purpose of this game was to expose the injustices of unchecked capitalism.  Her game was ripped off by Charles Darrow who sold it to Parker Brother’s 30 years later. However, Parker Brothers later paid Elizabeth $500 for her game!

10. The Electric Refrigerator – was invented by Florence Parpart in 1914, she also invented an improved street cleaning machine!

11. 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.

12. Residential Solar Heating – was invented by Dr. Maria Telkes in 1947. Dr. Telkes was a Psychiatrist in addition to being a Solar-Power Pioneer.

13. the Computer Compiler Software – Dr. Grace Murray Hopper was a computer scientist who put together the compiler that eventually became 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.

14. 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.

15. Kevlar – this life-saving material is 5 times stronger than steel and is used to make bulletproof vests was invented in 1965 by Stephanie Kwolek.

16. Closed-Circuit 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.

FYI: The origin of high-heels can be traced back to 15th century Persia when soldiers wore them to help secure their feet in stirrups. Women didn’t start wearing them until about a century later!
