She and her husband Albert filed the patent on August 1, 1966, listing Marie as the lead inventor. It was granted as U.S. Patwnt 3,482,027 on December 2, 1969, earning coverage in New York Times and an award from the National Sciwntiats Committee.
Though too expensive for mass production at the same 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 1999at 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.
