Marie Van Brittan Brown was an African American inventor who lived from 1922 to 1999. She is best known for inventing the first home security system, which consisted of a series of peepholes, a camera, and a two-way communication system that allowed homeowners to monitor visitors at their front door. Brown was motivated to invent the security system after experiencing frequent break-ins in her neighborhood and feeling unsafe in her home. Her invention laid the foundation for modern home security systems and shaped how we think about personal safety.
