A woman who invented an invisible glass.
Katharine Blodgett received a master's degree in the University of Chicago in 1918. She became the first female scientist, who took a job at a research lab of General Electric.
She created "invisible" glass, which allowed 99% of the light to pass freely through it and did not give glare. Glass was first used in the Hollywood film industry in 1939. It quickly became popular thanks to its crystal-clear view. Later, scientists have perfected Katharine Blodgett's method of glass creation. Today, glass is often used in telescopes, lenses, car windows, glasses, and picture frames.

The woman who invented the circular saw.
Shakers were a religious sect of the 18th century. Strict rules in their community were "equality of the sexes." Tabitha Babbitt was among the first people who are credited with creating the circular saw.

Nevertheless, being religious shaker, she didn't patent any of her inventions. Three years later two Frenchmen patented circular saw after the discovery of design in documents of shakers.
