Great Engineers & Scientists

In 1676, Sir Isaac Newton wrote "If I have seen further it is by standing on ye shoulders of Giants." In this blog, we take Newton's words to heart, and recognize the many great engineers and scientists upon whose shoulders we stand.

So who do you think of when you hear "Great Engineer"? Let us know! Submit a few paragraphs about that person and we'll add him or her to the pantheon. Please provide a citation for the material that you submit so that we can verify it. Please note - it has to be original material. We cannot publish copywritten material or bulk text taken from books or other sites (including Wikipedia).

Garrett A. Morgan

Posted February 06, 2010 9:30 AM by nsbe

Garrett A. Morgan was born in Kentucky in 1877. He was the seventh of eleven children born to Sydney Morgan, a former slave who was freed in 1863. Garrett Morgan spent many years teaching himself to repair sewing machines before opening his own business specializing in sewing machine sales and repair in 1907.

Eventually, Morgan opened his own tailoring shop, and it was here that he developed his first unique product. While attempting to solve a problem with scorched wool, Morgan invented a chemical solutions that caused hairs on a pony-fur cloth to straighten instead. Intrigued, he tried it on a neighbor's dog, and when it straightened the hair on the dog's coat, Morgan finally tried the new solution on his own hair. The success of the solution led Morgan to form G. A. Morgan Refining Company, the first producers of hair refining cream.

During his lifetime, Morgan continued to experiment with new products, inventing hat and belt fasteners and a friction drive clutch. His most significant invention, came in 1912, when he developed the "safety hood," the precursor to the modern-day gas mask. Granted a patent in 1914, the device, which consisted of a hood with an inlet for fresh air and an outlet for exhaled air, drew a number of awards. Although Morgan tested and demonstrated the use of the safety hood over the next few years, its most critical test occurred on July 24, 1916, during a tunnel explosion at the Cleveland Waterworks. The whole area was filled with noxious fumes and smoke, trapping workers in a tunnel under Lake Erie. Aided by his Breathing Device, Morgan went into the tunnel and carried workers out on his back, saving a number of men from an underground death. For this act of heroism, Morgan received the Carnegie Medal and a Medal of Bravery from the city, and the International Association of Fire Engineers made Morgan an honorary member. Not much later, Morgan established a company to manufacture and sell the Breathing Device in response to numerous orders from fire and police departments and mining industries. Fire fighters came to rely upon the gas mask in rescue attempts, and the invention helped save thousands from chlorine gas and other noxious fumes during World War I.

Next Morgan created the three-way traffic signal, a device responsible for saving thousands of lives over the years. The idea to build the warning and regulatory signal system came to him after he witnessed a carriage accident at a four-way street crossing. Once again, Morgan made sure to acquire a patent for his product, this time in Britain as well as the United States and Canada. Eventually, Morgan sold the rights to his invention to the General Electric Company for $40,000.

In addition to inventing new and unique products Morgan was actively involved in promoting the welfare of African Americans. In 1920, therefore, he began publishing the Cleveland Call, a newspaper devoted to publishing local and national black news. Additionally, Morgan served as an officer of the Cleveland Association of Colored Men, remaining an active member after it merged with the National Association for the Advancement of Colored People (NAACP).

Garrett Morgan died on August 27, 1963, at the age of 86. His life was long and full, and his creative energies have given us a marvelous and lasting legacy.

I work in the field of ammonia refrigeration. Occasionally workers in this area need to use gas masks, respirator hoods, or SCBA (self-contained breathing apparatus, but not underwater).

Because of this, I owe a debt to pioneers such as Garrett Morgan. I have enjoyed these threads that bring to light contributions that have been little known. Kudos to the NSBE for sharing these histories, and for reaching out to include women and other disciplines, such as medicine.
