We don’t actually know the individual who first created beer, but according to research conducted by historian Jane Peyton, for thousands of years brewing beer was a woman’s domain. According a 2010 Telegraph piece: “Nearly 7,000 years ago in Mesopotamia and Sumeria, so important were [women’s] skills that they were the only ones allowed to brew the drink or run any taverns.”

Margaret Knight realized that paper bags without square bottoms weren’t all that useful, so she invented a machine to cut and attach flat bottoms to bags. Before she could patent the iron version of her machine, a man named Charles Annan stole her design, claiming that no woman could think of something so complex. Knight filed a lawsuit against him and proved that the prototype was in fact hers. She gained the patent in 1871.

In 1886, socialite Josephine Cochrane was annoyed that her servants kept breaking her china. So, she invented the first workable dishwasher.

The first outdoor fire escape with an external staircase was patented by Anna Connelly in 1897. In the 1900s, Connelly’s model would become part of many mandatory building safety codes across the United States.

Monopoly, originally called The Landlord’s Game, was invented by Elizabeth Magie in 1903. Magie was inspired to create The Landlord’s Game “to demonstrate the tragic effects of land-grabbing.”

In 1903, Mary Anderson noticed drivers stopping to clear snow and ice off their windshields. She came up with the windshield wiper — an arm with a rubber blade that could be activated without getting out of your car. She applied for a patent in 1904, and it was issued in 1905. 

In 1930, Ruth Wakefield, who owned a lodge named the Toll House Inn, was making cookies for guests and realized that she was out of baker’s chocolate. She broke up pieces of a Nestle semi-sweet chocolate bar, thinking that the chocolate would mix in and melt during baking, but it didn’t. 

Dr. Maria Telkes worked at MIT on the university’s Solar Energy Research Project. In the 1940s, she developed the first solar-heated home with architect Eleanor Raymond.

Dr Grace Murray Hopper, a computer scientist, invented COBOL, the first user-friendly business computer software program in the 1950s. In 1969, she was awarded the first ever Computer Science Man of the Year Award. 

Stephanie Kwolek’s research with chemical compounds for the DuPont Company led her to invent Kevlar — the material used in bulletproof vests — which was patented in 1966. 

Ann Tsukamoto is one of two people who got a patent in 1991 for a process to isolate the human stem cell. Her work has led to advancements in comprehending the blood systems of cancer patients and could eventually lead to a cure.

Who is Nicolás tesla?
A short history aborto him.

Thomas Edison´s greatest challenge was the development of a practical incandescent, electric light. Contary to popular belief, he didn´t ´´invent´´ the lightbulb, but rather he improved upon a      50--year--old idea. In 1879, using lower current electricity, a small carbonized filament and an improved vacuum inside the globe, he was able to produce a reliable, long--lasting source of light.

able to record sound and play it back, followed by the gramophone, invented by Berliner in 1888. In the late 1980s, fax technology was a breakthrough 

for international development organizations since it enabled extremely rapid document delivery to remote areas via regular telephone lines. Unlike the phonograph, the gramophone used 

not a cylinder but a flat disc, with which thousands of copies could be made of the same recording. A coin-operated phonograph developed fromEdison's invention emitted recorded sounds. A coin-operated phonograph developed fromEdison's invention emitted recorded sounds. President Bliss had demonstrated an Edisonphonograph at the American University of Beirut. Thomas Edison's invention has changed theworld, but we 

often take electricity for granted. I know that learning is not

 only repeating like a phonograph and abstractly but applying 

in real life what we have been studying. Thomas Edison produced the light bulb and, with George Eastman, the moving picture. Despite all claims to the contrary, the first

 lightbulb was not invented by the American Thomas Edison, but rather by a German.
