Behind some of the world’s most common household items, security systems, and medical devices are the brilliant minds of Black women inventors.
Often overlooked by history, their ingenious solutions to everyday problems have shaped our modern lives in profound and lasting ways.
This listicle celebrates five pioneering women whose patents paved the way for the technology, comfort, and safety we often take for granted today.
1. Sarah Boone: Revolutionizing Home Care with the Modern Ironing Board (1892)
Long before wrinkle-free fabrics, ironing clothes was an arduous task done on wooden planks. Sarah Boone, a dressmaker, patented an improved, narrow, curved-board design specifically to iron the sleeves and bodies of women’s garments. Her invention is the direct ancestor of the adjustable ironing board in homes worldwide, forever changing domestic labor and textile care.
2. Marie Van Brittan Brown: The Pioneer of Home Security Systems (1966)
Concerned about slow police response in her New York City neighborhood, nurse Marie Van Brittan Brown co-invented the first home security system.
Her revolutionary design used a motorized camera, peepholes, monitors, and a two-way microphone to see and speak to anyone at the door. It even included a remote-controlled door lock and an alarm button to alert authorities. Her 1966 patent laid the foundational technology for all modern closed-circuit television, surveillance systems, and smart home security.
3. Miriam E. Benjamin: The “Signal” Chair Preceding Flight Attendant Calls (1888)
Teacher and inventor Miriam E. Benjamin patented a chair with a novel signaling system. A button on the chair would light a signal lamp for attendants, allowing for discreet service. This ingenious idea was adopted by the U.S. House of Representatives and is recognized as a key precursor to the flight attendant call buttons used on airplanes today—a simple innovation in communication technology for service industries.
4. Bessie Blount Griffin: Medical Aids for Veteran Independence (1940s-50s)
A physical therapist, forensic scientist, and inventor, Bessie Blount Griffin created medical devices to assist injured WWII veterans. She invented an electric self-feeding device that delivered small bites of food with a simple bite motion, allowing amputees to eat independently. Her compassionate ingenuity in assistive technology and rehabilitation equipment provided newfound dignity and autonomy to countless patients.
5. Dr. Patricia Bath: A Laser Innovation That Restored Sight to Millions (1986)
Ophthalmologist and laser scientist Dr. Patricia Bath broke barriers as the first Black female physician to receive a medical patent. She invented the Laserphaco Probe, a device using laser technology to painlessly dissolve cataracts and restore vision.
Her groundbreaking invention in cataract surgery and ophthalmic instruments is used globally, having given the gift of sight to millions of people.
From the ironing board in your laundry room to the security camera at your door, the legacy of these five Black women inventors is woven into the fabric of daily life. Their stories are powerful reminders of innovation born from necessity, observation, and a desire to improve the human experience. Their historical patents in women’s history, technology, and medicine continue to resonate, proving that impactful invention knows no bounds.
