Marie Van Brittan Brown
The Nurse Who Secured Our Homes


Four peepholes on the front door at different heights (for adults, children, and everyone in between). A sliding camera that moves to view through each peephole, sending live images to a monitor inside. A two-way microphone for talking to visitors without opening the door. A remote-controlled door lock for safe entry. A panic button that instantly alerted police. She and her husband, Albert, filed the patent on August 1, 1966, listing Marie as the lead inventor. It was granted as U.S. Patent 3,482,027 on December 2, 1969, earning coverage in the New York Times and an award from the National Scientists Committee. Though too expensive for mass production at the time, Marie’s design revolutionized security. Her patent has been cited in over 25 others, influencing everything from bank surveillance to apartment complexes and Ring doorbells. Today, as a multi-billion-dollar industry, home security protects millions, all tracing back to a Black woman’s foresight. Marie passed away in 1999 at age 76, never seeing her full legacy unfold. Yet her story endures: an everyday nurse turned innovator, proving that protecting your home starts with protecting your ideas. In Black History Month, Marie Van Brittan Brown reminds us that true influence comes from solving problems no one else sees.
