Garrett Augustus Morgan Born: March 4, 1877 Died: August 27, 1963 Birthplace: Paris, Kentucky Garrett Augustus Morgan: Traffic Engineer Garrett Augustus Morgan was born in Paris, Kentucky on March 4, 1877.

Firefighters in many cities in the early 1900's wore the safety helmet and gas mask that he invented, and for which he was awarded a gold medal at the Second International Exposition of Safety and Sanitation in New York in 1914. The gas mask Morgan invented in 1912 ( U.S. 1,113,675 issued in 1914) was during World War I to protect soldiers from chlorine gas fumes. In 1916, Mr. Morgan used his own mask design to rescue men trapped by a gas explosion in a tunnel being constructed under Lake Erie. Following disaster, which killed twenty-one people, the City of Cleveland, Ohio honored Garrett Morgan with a gold medal for his heroic efforts.

USA/Canada Garrett Augustus Morgan: American Inventor Garrett Augustus Morgan (March 4, 1877 - August 27, 1963), was an African-American inventor and businessman. He was the first person to patent a traffic signal. He also developed the gas mask (and many other inventions). Morgan was born in Paris, Kentucky , and was the son of former slaves (and the 7th of their 11 children). His formal education ended during elementary school. As a a teenager (in 1895), Morgan moved north to Cincinnati, Ohio , looking for opportunity. His incredible ability to repair machinery led to many job offers from factories. In 1907, he started his own sewing equipment and repair shop. His business expanded in 1909; he employed 32 people, who used equipment that Morgan made (and invented) himself. In 1920, Morgan went into the newspaper business, starting the "Cleveland Call." He was very successful, and eventually bought a car. While he was driving along the streets of Cleveland, he realized how unsafe intersections were, and was determined to make driving safer. Morgan patented a traffic signal on November 20, 1923 (U.S. patent No. 1,475,024, issued in 1923) - this was the first traffic signal patented, but not the first invented. His traffic signal was a T-shaped pole with arms (but with no lights) that has three signs, one or more of which popped out at a time: a red "stop," a green "go," and another red "stop in all directions." This last signal let pedestrians cross the street. It was controlled by an electric clock mechanism. This device became very popular, and was used all around the USA. Morgan sold his device to the General Electric Corporation for $40,000 (a huge sum at that time). His device was used until the three-light traffic light was developed.

THE GARRETT A. MORGAN TECHNOLOGY AND TRANSPORTATION FUTURES PROGRAM EDUCATING TOMORROW'S TRANSPORTATION WORKFORCE An American Inventor Garrett Augustus Morgan, Sr. Garrett Augustus Morgan, Sr. was an American inventor whose curiosity and innovation led him to develop several commercial products, the successors of which are still in use today. A practical man of humble beginnings, Morgan devoted his life to creating items that made the lives of common people safer and more convenient. Among his creations was the three-position traffic signal, a traffic management device that greatly improved safety along America's streets and roadways. Morgan's technology was the basis for the modern-day traffic signal and was a significant contribution to development of what we now know as Intelligent Transportation Systems. The Inventor's Early Life Garrett Augustus Morgan, Sr. was born in Paris, Kentucky on March 4, 1877. His parents were former slaves. Morgan spent his early childhood attending school and working with his brothers and sisters on the family farm. He left Kentucky while still a teenager, moving north to Cincinnati, Ohio in search of employment.

Who is Garrett A. Morgan 1877-1963? Garrett Augustus Morgan was born in 1877 in Paris, Kentucky. He dropped out of school at the age of 14 and moved to Cleveland Ohio where he began working at a sewing-machine shop. He became interested in the improvement of machines and designed a belt fastener for the sewing machine, which he sold for $150. In 1909, Morgan opened a clothing manufacturing company and continued to invent new devices. Morgan was interested in workers’ safety. He invented a safety hood, called an “inhalator,” which he patented in 1912 (patent #1,113,675). This device was an early version of the gas mask. He won the grand prize for the invention in 1914 at the second International Exposition of Safety and Sanitation. bodyOffer(16772) Morgan did not let prejudice against him stop his efforts to invent devices to make the world a safer place. In 1920, the use of the automobiles increased, causing traffic congestion in many of the large U.S. cities. In 1923, Morgan designed and patented a traffic signal (patent #1,475,024). The signal consisted of a tall post with movable arms that monitored and controlled traffic. The post rotated and the arms moved up. The signal contained lights that flashed the words ”stop” and “go.” The posts used batteries and electricity from overhead wires. A set of bells signaled that the post was changing direction. Morgan sold the rights to his traffic signal patent to the General Electric Company. Many modern day traffic signals still incorporate the features of Morgan’s early invention.
