Year: 1821​
Who: Thomas L. Jennings (1791 – 1859)​
Where: New York City​, New York
What: Thomas Jennings made history in 1821 as the first African American to receive a U.S. patent. His innovative "dry scouring" method revolutionized clothing care by removing dirt and grease without damaging the fabric's shape or appearance. This invention laid the groundwork for modern dry cleaning, benefitting countless households and industries. Jennings’ groundbreaking achievement was particularly significant in a time when systemic racism created substantial barriers for African Americans, including access to patents and recognition of their contributions. His patent success represented a triumph over the pervasive racial inequities of the 19th century.
Born free in New York City, Jennings leveraged his skills as a tailor to establish a successful clothing business in Manhattan. His inventive process became a hallmark of his entrepreneurial spirit, earning him both financial success and national acclaim. Although the details of his dry scouring method were lost in the devastating 1836 Patent Office fire that destroyed thousands of records, Jennings’ impact endures through his legacy of ingenuity and determination.
Jennings used the profits from his invention to advocate for equity and justice. A dedicated abolitionist, he supported numerous causes aimed at ending slavery and improving the lives of African Americans. He helped establish the influential Freedom's Journal, the first Black-owned newspaper in the United States, and was a significant supporter of the Abyssinian Baptist Church in Harlem. His wealth also funded legal battles for racial equality, including his daughter Elizabeth Jennings’ landmark case challenging racial discrimination in public transportation. This case set an important precedent for civil rights.
Jennings’ achievements underscore the vital role of inclusivity in innovation. Despite systemic obstacles, his work highlights the transformative potential of diverse perspectives in technology and equity ethics. His story remains a powerful testament to resilience, creativity, and the enduring fight for justice.
