Showing a great natural talent for invention, his master referred him to the United States Naval Academy in Annapolis, Maryland to take up a position as an assistant in their Department of Natural and Experimental Philosophy. He was the first African American to hold any non-menial post at the Naval Academy. It was here that he developed his own design for a steam engine.

Being a slave, he was not able to patent his invention - he did sell the rights to it, however, and used the money to buy his own freedom.

33. Brown, Marie Van Brittan, and Brown, Albert

Source: Timeline

Selected Invention(s):

- Home security system utilizing television surveillance (Date: December 2, 1969, Patent No: 3482037)

Additional information: Marie V. B. Brown was born in 1922 and as an adult, she lived in a crime-ridden neighborhood of Queens, NYC. Brown worked as a nurse, and her husband, Albert Brown, was an electronics technician. Their work hours meant that Brown was often home by herself. Concerned about the slow police response times to their neighborhood, Brown created a system that would allow her to know who was at her home and contact authorities quickly in the event of a break-in.

Her original invention was included peepholes, a camera, monitors, a two-way microphone, and an alarm button to contact the police. Brown’s security system was the foundation for modern, two-way communication and surveillance systems. Brown’s invention gained her an award from the National Scientists Committee.
