Necessity isn't the only mother of invention. In spite of the fact that it wasn't simple to get patents or the credit they merited, ladies have been in charge of numerous items we utilize today.
With Women's Day right around the bend, here's to the ladies who invented things we can't imagine our existence without:
In 1868, Margaret Knightwood invented a machine that collapsed and stuck paper to frame the level bottomed brown paper bags. We at last owe it to Margaret Knightwood for the helpful paperbag that comes handy just about everywhere!
Kevlar is a super-strong fibre that is used for making bullet-proof vests. It was invented by Stephanie Klowlek. Kevlar is five times stronger than steel and has more than 200 other uses.
Marie Van Brittan Brown's invention is the basis for modern day CCTV systems. In New York City, when Marie Van Brittan Brown observed that police were slow to respond to calls for help at times, she took matters into her own hands and invent the system for CCTV (Closed-Circuit Television) security to help people ensure security of their homes.
Katharine Blodgett's invention of non-reflective glass is essential for eye-glasses, car windshields and computer screens. Her “invisible” glass was initially used for lenses in cameras and movie projectors. It also had military applications such as wartime submarine periscopes during World War II.
One day in 1882, Maria Beasley looked out at the sea and said, "People should, like, stop dying in huge transportation disasters." She also invented a machine for making barrels which got her the riches.
