Thomas L. Jennings
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 successful dry-cleaners can thank Mr. Jennings for his early innovation published to the world in 1821. Jennings used the profits secured from his patent to free members of his family who were still under slavery systems in some of the U.S. Jennings also used his wealth as a business man and inventor to financially support the abolition movement that was growing in many areas throughout the U.S. during his time.
