Science and Technology: African Inventors in the Americas (2024)

We learn very little about inventors of African descent. The inventors highlighted heredo not represent an exhaustive list. Itincludes some of the early inventors in the Americas, whetherindependent, corporate or government inventors. Notably, the drive to make the food production process more efficient after the abolition of slavery in the Americaswas not lost on many of these innovators.

Thomas L. Jennings was the first African to receive a patent in the United States of America. On March 3, 1821 he secured US Patent 3306x for discovering a process called dry-scouring. Jennings lived in New York as a free man. He owned and operated tailoring and clothing cleaners business. Dry-scouring is a process he developed for cleaning clothing through a dry process instead of a wet process. Yes, the successfuldry-cleaners can thank Mr. Jennings for his early innovation published to the world in 1821.

Granville T. Woodsfocused his innovation in the area of railway electronic communication systems. On June 3, 1884, Woods received his first patent. This was for an improved steam-boiler furnace, U.S. Patent No. 299,894. Subsequently, Alexander Graham Bell's company would purchase the rights to his telegraphony patent, a device that allowed a telegraph station to send voice and telegraph messages over a single wire. The relationship with the Bell company enabled Woods to become a full-time inventor. Woods would go on to receive a patent for an automatic air brake, which is used to slow and stop trains.

John Standard obtained U.S. Patent No. 455,891. Born July 1891, John Standard was born in New Jersey. He improved on the original icebox by putting cold air-ducts or holds in special areas to help the air circulate within the icebox in order to keep foods fresher. His invention also provided a special place to keep the drinking water and other drinks separate from the food. This avoided liquids picking up the flavors and smells of other foods.

This helped preps determine whether it was ready. He also included a plate inside the churn for the butter to be placed for easier removal. Richardson's U.S. patents include the following:

• 255,022, 3/14/1882, Hame fastener
• 446,470, 2/17/1891, Churn
• 529,311, 11/13/1894, Casket-lowering device
• 620,362, 2/28/1899, Insect destroyer
• 638,811, 12/12/1899, Bottle

Judy W. Reed 1884 patent for dough kneading

Judy W. Reedreceived U.S. Patent No. 305,474, received September 23, 1884, for a hand-operated dough kneader and roller that allowed for improved mixing that was more evenly distributed when processed through the rollers with corrugated slates. Little is written about Reed's life, but she has garnered the title of being the first African-American woman to receive a U.S. patent.

Joseph Lee received U.S. Patent No. 524,042 for a kneading machine invention on August 7, 1894. Lee's time saving invention mixed and kneaded the dough and also replaced the need to hand roll dough.

Robert P. Scott invented the corn silker and obtained U.S. Patent No. 524,223 on August 7, 1894. Corn silk is the silk-like thread fibers on the inside of the green husks removed from corn-on-the-cob. Removing corn silk proved both time consuming and difficult. The R.P. Scott Corn Silker helped to make this process faster and more efficient.
