12 inventions by women that changed the world.

2. 1. THE CAR HEATER
The first car heater, which directed air from over the engine to
warm the chilly toes of aristocratic 19th-century motorists,
was invented by Margaret A. Wilcox in 1893.

3. 2. The Monopoly
One of the most famous board games of all time, responsible for endless
hours of wholesome family fun was invented by Elizabeth Magie in
1904 under the original name The Landlord’s Game. Magie’s game was a
critique of the injustices of unchecked capitalism, making it all the more
ironic when her game was completely ripped off ( stolen from) by Charles
Darrow 30 years later, who sold it to Parker Brothers. The firm eventually
tracked down Magie and paid her $500 for her troubles.

4. 3. THE FIRE SCAPE
This device, so vital both to public safety and the
smoking habits of urban hipsters (hippie) , was
invented in 1887 by Anna Connelly.

5. 4. THE LIFE BOAT
One day in 1882, Maria Beasely looked out at the sea and said,
“People should, like, stop dying in huge transportation disasters.”
And then she invented life rafts.

6. 5. Residential solar heating
Physicist and solar-power pioneer Dr. Maria Telkes teamed the
architect Eleanor Raymond, to build the first home entirely heated
by solar power in 1947.

7. 6. Kevlar
The chemist Stephanie Kwolek invented the super-strong Kevlar
fibre, used to make bulletproof vests. Kwolek’s invention is five
times stronger than steel.

8. 7. Computer Software
Dr Grace Murray Hopper, a rear admiral in the U.S. navy, was
also a computer scientist who invented COBOL, “the first user-
friendly business computer software program”. She was also the
first person to use to term “bug” to describe a glitch in a
computer system.

9. 8. BEER
Beer is totally a girl’s drink. Beer historian Jane
Peyton claims that ancient Mesopotamian women
were the first to develop, sell, and even drink beer

10. 9. THE CCTV
Marie Van Brittan Brown’s system for closed-circuit television
security, patented in 1969, was intended to help people ensure
their own security, as police were slow to respond to calls for
help in her New York City neighbourhood. Her invention forms
the basis for modern CCTV systems used for home security and
police work today.

11. 10. Wireless transmissions technology
Hedy Lamarr’s invention of a
secret communications system
during World War II for radio-
controlling
torpedoes, employing
“frequency hopping”
technology, laid the
technological foundations for
everything from Wi-Fi to GPS.
She also happened to be a
world-famous film star.

12. 11. Many telecommunications
technology
The theoretical physicist Dr
Shirley Jackson was the first
black woman to receive a Ph.D.
from MIT, in 1973. While
working at Bell Laboratories, she
conducted breakthrough basic
scientific research that enabled
others to invent the portable
fax, touch tone telephone, solar
cells, fiber optic cables, and the
technology behind caller ID and
call waiting.

13. 12.The computer algorithm
Ada Lovelace, whose father was Lord Byron, was encouraged by
her scientist mother from a young age to become a champion of
mathematics. Lovelace worked with Charles Babbage at the
University of London on his plans for an “analytic engine” (i.e.
old-timey computer) to develop ways to program the machine
with mathematical algorithms, essentially making her “the first
computer programmer”.
