On this day, Thomas L. Jennings was formally recognized for his groundbreaking achievement as the first African American to receive a U.S. patent. In 1821, he was awarded a patent for a dry-cleaning process called “dry scouring.” Jennings used the proceeds from his invention to support abolitionist causes. He was also an activist and served as Assistant Secretary at the first annual Convention of the People of Color in 1831. His legacy bridges innovation and civil rights, setting a precedent for generations of Black inventors and leaders.
