Marie Van Brittan Brown

Marie Van Brittan Brown (October 30, 1922 – February 2, 1999) was an American nurse and inventor best known for co-creating one of the earliest home security systems. Brown lived most of her life in the Jamaica, Queens area of New York City, a community that experienced significant increases in crime during the 1960s. Her profession required her to work long and irregular hours, including nights and weekends. Her husband Albert L. Brown, was an electronics technician and he had inconsistent work schedules. In 1966 they invented an audio-visual home security system ("Home Security System Utilizing Television Surveillance"). That same year they applied for a patent for their security system. It was granted three years later in 1969. Her father, Theodore Felton, was born in North Carolina and her mother, Lillian Robinson was from Pennsylvania. Both were African-American.

Marie married Albert L. Brown, also African-American, in 1949. The couple lived at 151–158 and 135th Avenue in Jamaica, Queens, New York. Marie and Albert had two children. Their daughter also became a nurse and inventor.

Marie died in Queens on February 2, 1999, aged seventy-six.

In 1966, Brown and her husband began working together to develop a home security system. Their invention used closed-circuit television technology, which at the time was still relatively uncommon in residential settings. The system was designed to allow homeowners to see who was at their door and communicate with visitors without opening the door, reducing the risk of potential danger.

Patent On August 1, 1966, the Browns submitted a patent application for their invention. Their attorneys were Polacheck and Saulsbury, a New York firm. Marie was quoted in the New York Times as saying that with her invention "a woman alone could set off an alarm immediately by pressing a button, or if the system were installed in a doctor's office, it might prevent holdups by drug addicts". At the time, the equipment required to produce the system, including cameras, monitors, and electronic components, was expensive and not commonly available for residential use. Additionally, many homeowners were unfamiliar with surveillance technology, which limited consumer interest.

Legacy The Brown's patent has been cited in 38 patent applications. The security system developed by Brown introduced essential security concepts that security technology continues to use today. The video surveillance system with distant communication that Brown developed in 1966 serves as the base for all modern smart home systems. The security system design elements she created for video doorbells and smart locks, and home automation systems now protect millions of households worldwide. Brown achieved her technical objective, yet her success led to social effects that surpassed her initial intentions. Brown encountered extreme difficulties in the security technology field of the 1960s because she was an African American woman working among white male professionals. The world recognizes her as a leading figure who broke down barriers for underrepresented groups in STEM fields and innovation through her patent achievements and recognition. Educational programs and STEM initiatives use Brown's achievements to motivate girls and minority students toward technology and engineering career paths. She created the security system because her Queens neighborhood required protection from crime, since police took too long to respond. The innovation solved actual community requirements through the combination of different viewpoints, which produced better technological outcomes. The security industry started focusing on residential systems after Brown's invention by more than twenty years before the market began to show interest in this area. The patent documentation reveals its influence on future security patent development through its documented citation history. The security systems we use today, including video intercoms and advanced surveillance systems, derive their concepts from Brown's first design. The system components, which included a camera and monitor, and two-way microphone, and remote door controls, became the foundation that manufacturers used to create new security products throughout multiple decades. The world has started to understand Brown's achievements at a higher level since the beginning of this decade. Security technology experts now recognize Brown as a key figure who helped create the security technology industry.

The Smithsonian Institution, along with other museums, has displayed her work in exhibits that honor African American inventors and women in technology. Digital archives, together with educational resources, now present Brown's story alongside other groundbreaking inventors to teach future generations about her achievements. The security system she created continues to influence modern discussions about surveillance and privacy and their relationship with technology in society. Through her invention, she created a security system that allowed people to defend themselves, while today we face similar challenges about security versus privacy in our monitored society. The commercial security industry has accepted Brown's fundamental security system concepts by using them to develop their products. The security industry started using consumer products instead of commercial and industrial systems because Brown worked to develop security systems that were easy to use and accessible to everyone. The security technology revolution brought protective systems to ordinary homeowners, which transformed their expectations about safeguarding their properties and personal safety.
