What did Women give us? – Part 2

So as a continuation from our last post, here are some other amazing things that women gave us.

Let us begin:

LIQUID PAPER

Before computers (that women gave us mind you) there was the typewriter. Although a revolutionary piece of technology, there was no way to fix typos and mistakes, so secretary Bette Nesmith Graham then spent the next few years perfecting the formula in her kitchen, before calling it “Liquid Paper” in 1958.

THE APGAR SCORE

Named after the obstetrical anesthesiologist Dr. Virginia Apgar, in 1952 Dr. Apgar began testing newborns one minute and five minutes after birth to determine if they needed immediate care. Ten years after, the scientific community came up with a backronym (an acronym that is made to fit around an already existing word) Appearance, Pulse, Grimace, Activity, and Respiration.

SIGNAL FLARES

Back in the cay ships would communication with coloured flags and loud noises. After finding plans from her late husband, Martha Coston spent 10 years working with chemists and pyrotechnics experts to make the idea a reality. But she was only named administratrix in the 1859 patent—Mr. Coston got credited as the inventor.

THE CIRCULAR SAW

Tabitha Babbitt was the first to initially suggest to use a circular saw to cut instead of a two-man pit saw. And although she made the prototype and attached it to her spinning wheel in 1813, her community did not approve of her filing a patent, but did take full advantage of her work.

INVISIBLE GLASS

Katharine Blodgett, General Electric’s first female scientist (bad ass) discovered a way to transfer small monomolecular coatings to glass and metals in 1935. By doing so she was able to eliminate glare and distortion, revolutionizing cameras, microscopes, glasses, and so many other things.

SUBMARINE TELESCOPE AND LAMP

Although there is little information about Sarah Mather, the early inventor, we do know that her contributions, by combining the telescope and the lamp together for submarines is a tribute to her.

THE SOLAR HOUSE

Maria Telkes, a biophysicist, was the first person to have a 100 percent solar house. In 1947, the Hungarian scientist invented the thermoelectric power generator to provide heat for Dover House, a wedge-shaped structure she conceived with architect Eleanor Raymond. She was able to use Glauber’s salt, the sodium salt of sulfuric acid, to store heat in preparation for sunless days. Dover House survived nearly three Massachusetts winters before the system failed.

SCOTCHGUARD

In 1952, 3M chemist Patsy Sherman was interested when fluorochemical rubber spilled on a lab assistant’s shoe and wouldn’t come off, the chemical didn’t change the colour of the shoe, the stain repelled oil and a few other liquids. Patsy and her co-inventor Samuel Smith called it Scotchguard.

So which ones of these surprised you the most?
