African American Achievements in SafetyFeb 07, 2019
These safety pioneers had a vision and made life safer for others. Their inventions in rail and traffic safety, chemical and electrical safety, aerospace safety, communications and health greatly improved how we work and live today.
They were innovators and inspirations—and they made a difference.
Born a free man, Martin received a patent on March 26, 1872, for the first fire extinguishing suppressing apparatus, which later was remodeled as a portable extinguisher.
Woods made train communication between the station and other trains possible by inventing the “Synchronous Multiplex Railway Telegraph.” He is also responsible for inventing automatic air brakes for trains and the “third rail” concept, all being used in mass-transit rail systems today.
George Washington Carver
Carver’s studies on soil depletion found that farmers could utilize crops such as peanuts to support their soil as well as their way of life. He taught at the Tuskegee Institute for nearly 50 years, sharing his knowledge of farming techniques and how crop rotation could improve the quality of soil and produce crops that were better for human consumption.
Garrett A. Morgan
Morgan’s safety helmet was used by the allied forces in World War I and served as the prototype for the modern-day respirator. He also patented the directional traffic signal, later changed to three colors, which now directs traffic on most roads and highways around the world.
In 1958, Chappelle joined the Research Institute for Advanced Studies in Baltimore, a division of the Martin Marietta Corporation that was famous for designing airplanes and spacecraft. There, Chappelle discovered that even one-celled plants such as algae, which are lightweight and can be transported easily, can convert carbon dioxide to oxygen. This discovery helped to create a safe oxygen supply for astronauts.
Marie Van Brittan Brown
Brown developed a video monitoring system consisting of four peep-holes and a camera, which could be utilized to view the activity around her home. The system allowed her to view someone at her front door, hear their voice and was equipped with a button to notify police, if necessary. This invention would pave the way for the video security systems that homes and businesses use today.
