Marie Van Brittan Brown lived in the Jamaica neighborhood of Queens, New York in 1966. Her neighborhood suffered from a high rate of crime, and she noted the relatively slow response time to calls for police assistance. Brown worked as a nurse, her husband as an electrician, and their work schedules seldom coincided with each other. Both were concerned about their safety, especially at night. They worked together to create a home security system, which employed a camera which displayed images of someone outside their front door on a television set in their home. The camera could be maneuvered from inside the door, and was supplemented by peepholes.
They patented their system in 1966. It was the first closed-circuit television (CCTV) system, and variations of the design became ubiquitous around the world. Security cameras which record images came into existence in businesses, homes, and public areas around the world. As of 2016, according to a report by New Scientist Magazine, over 100 million CCTV systems operated around the world, helping prevent crime. They also became invaluable in helping investigators solve all forms of crime, identifying miscreants through the support of the public.

24. Sarah Breedlove
Sarah Breedlove was born in Louisiana in 1867, to a family so poor that she was forced to work as a domestic servant as a child, following the death of both her parents. She married twice, her first husband died, her second was abusive and she abandoned him. In 1906 she met and married Charles Joseph Walker, a salesman. She began calling herself Madam C. J. Walker. Though they divorced in 1912 she continued to use the name. In the early twentieth century, she developed hair care products for her personal use, as well as for friends and family, using expertise provided by her brothers who worked as barbers in St. Louis.
In 1910, while still married, she started the Madam C. J. Walker Manufacturing Company, creating hair products and other toiletries for African-Americans. By 1919 she employed several thousand black women to market her products across the United States, especially in the south. They marketed her products door-to-door and in beauty parlors and barber shops. As her famed and influence grew, Sarah became active in philanthropy, civil rights, and women’s rights. Before she died in 1919 Sarah went from a dirt-poor orphan to America’s first self-made female millionaire. Her company continued to operate until 1981.
