Mr. and Mrs. Brown's nvention was cited in at least 32 future patent applications

 

Marie Van Brittan Brown 

(October 30, 1922 – February 2, 1999)  

 

  The effects of Brown's home security system cannot be understated. She was recognized in the New York Times and received an award from the National Scientists Committee for her work.^[11] 

 

As more home security systems came to the market, Brown's initial invention became even more influential. Her invention was cited in at least 32 future patent applications.^[12] 

 

After her successful patent application in 1969, the media coverage of her product ceased.^[13] The home security business is expected to be at least a $1.5B business and is expected to triple by 2024.^[14] 

 

However, Brown will not be able to profit from that growth. ^[15] Her initial invention was the foundation of most home security systems that are around today.
