Famous Inventions by Women

A Shaker community in Massachusetts had a woman named Tabitha Babbitt who worked as a weaver. She would regularly witness the men cutting the wood with a pit saw (a two-handled saw that needed two individuals to operate). Although the saw needed to be pulled in two directions to cut the wood, there was only cutting going on when the saw was being pulled in a forward direction making the backward motion useless. In 1810 Babbitt developed her own draft of a saw that was circular in shape and would eventually be commonly used in saw mills. She attached the blade to her own spinning wheel in order to make every movement count toward cutting results.

Admiral Grace Murray Hopper joined the military during 1943 and was stationed at Harvard University where she was employed using IBM’s Harvard Mark I computer, which was the first large-scale computer in the US. She was the third individual programming the machine and she wrote a handbook of operations that led the way for many that would follow her. During the 1950s, the Admiral came out with the compiler, which converted English instructions into a computer code. This meant that computer code could be developed by programmers with less errors and complications. Hopper then created the Flow-Matic, which was utilized to program the UNIVAC I and II computers. Hopper had also been overseeing the advancements of Common Business-Oriented Language or (COBOL), which was one of the very first computer languages. She went on to obtain various awards for her work and even had a US warship named after her. Heard her speak one time and she used a length of wire 11.8 inches long as a prop. She described how light traveled that distance in one nanosecond.
