If you make a list of the most famous inventions of the last few centuries, among the authors of these inventions will be very few women. And it's not that women do not know how to invent or do not have a creative bone, but they face many obstacles in getting "credit" for their ideas.
Take, for example, the case of Sybil Masters (Sybilla Masters), a woman who lived in the American colonies. Observe the work of Indian women, she came up with a new way to turn corn into cornmeal. Sybil went to England to obtain a patent for his idea, however, if the current law, women were forbidden to have their property, including intellectual. This property is usually owned by a woman or her father or her husband. In 1715, a patent for her invention yet been issued, but the document was the name of her husband.
Mary Kies (Mary Kies) was the first American woman who has registered a patent for his name. In 1809, it developed a method of weaving straw hats, it was an economic boon for New England. After receiving the document in his own name, Mary thus opened the way for other women to the inventors to patent their ideas. Both women were quick to take advantage.
1. Circular Saw
In the late 18th century there was a Protestant religious sect known as the Shakers. The main values of this sect were communal life, gender equality and hard work. Tabitha Babbitt (Tabitha Babbitt) lived in sheykerskom community in Massachusetts and worked as a weaver, but in 1810 she came up with a way to lighten the load on the work of his brothers. She noticed that men sawing logs a special saw with two handles, you need to pull it back and forth. Although the load on the two men was the same, sawn timber only when the saw is moving forward and in reverse motion with the log, nothing happened. Babbitt thought it was a waste of energy, and created a prototype of a circular saw, which later came to be used in the sawmill industry. She came up with a circular saw blade, so every move made sense. However, because of the commandments of the community, Babbitt did not receive a patent for his invention.
