1. The computer algorithm
Ada Lovelace, whose father was Lord Byron, was encouraged by her scientist mother from a young age to become a fucking champion of mathematics. Lovelace worked with Charles Babbage at the University of London on his plans for an “analytic engine” (i.e. old-time computer) to develop ways to program the machine with mathematical algorithms, essentially making her “the first computer programmer”.
2. More telecommunications technology than you could shake a stick at
The theoretical physicist Dr Shirley Jackson was the first black woman to receive a PhD. from MIT, in 1973. While working at Bell Laboratories, she conducted breakthrough basic scientific research that enabled others to invent the portable fax, touch tone telephone, solar cells, fiber optic cables, and the technology behind caller ID and call waiting.
3.Wireless transmissions technology
Hedy Lamar's invention of a secret communications system during World War II for radio-controlling torpedoes, employing “frequency hopping” technology, laid the technological foundations for everything from Wi-Fi to GPS. She also happened to be a world-famous film star.
4.CCTV
Marie Van Brittan Brown’s system for closed-circuit television security, patented in 1969, was intended to help people ensure their own security, as police were slow to respond to calls for help in her New York City neighborhood. Her invention forms the basis for modern CCTV systems used for home security and police work today.
5.The paper bag as you know it
Margaret Knight received her patent for a machine that could produce square-bottomed bags in 1871, after a long legal battle with a fellow machinist, Charles Anan, who tried to steal her work by arguing that such a brilliant invention could not possibly have been invented by a girl. That gentleman has thankfully been forgotten by history. Also, when Knight was 12 years old, she invented a safety device for cotton mills which is still used today.
