National Inventor Day

Today marks National Inventor Day. Human history is full of inventions that can be credited to women, but we rarely learn about them in school since most of the literature taught in schools is written by white male authors. I thought it would be a great time to talk about a few female inventors that have changed the world:

beer-barrel-956322_1920Maria Beasley invented the life raft in 1882 because she didn’t want anyone else to die at sea. She invented a life raft that was compact, fireproof and ready to launch. Maria was born in Philadelphia. She also invented the machine for making barrels. Maria had 15 patents between the years 1878-1898. She was a successful inventor and business woman.

Anna Connelly invented the fire escape in 1887, a device that is vital for public safety.

tableware-555203_1920Josephine Cochrane invented the dishwasher in 1887. She was the daughter of a civil engineer. Her maternal grandfather, John Fitch, was the inventor of the steamboat. Josephine was posthumously inducted into the National Inventors Hall of Fame in 2006.

Margaret A. Wilcox invented the car heater in 1893. She also invented combined clothes and dish washer. The air would flow over the engines for the purpose of warming the chilly toes of the aristocratic motorists. Margaret was a mechanical engineer. She had a lab in which she would do experiments and work on different creations.

Florance Papart invented the modern electric refrigerator in 1914. She also improved the street-cleaning machine, which was sold to cities across America.

Alice Parker invented central heating in 1919.
