The short answer: Thomas L. Jennings is widely credited as the first inventor of a dry-cleaning–type process, while Jean-Baptiste Jolly later popularized what became modern commercial dry cleaning.

Who Invented Dry Cleaning?

The First Patent: Thomas L. Jennings

Most historians point to Thomas L. Jennings , an African American tailor in New York City, as the first person to invent and patent a dry-cleaning method.

  • In 1821, Jennings received a U.S. patent for a process he called “dry scouring,” designed to remove stains and dirt from delicate fabrics without ruining them.
  • His patent is considered one of the earliest formal descriptions of a dry-cleaning technique and made him the first known African American to hold a U.S. patent.
  • Jennings developed the method because his tailoring customers complained that traditional washing destroyed their clothes, so he experimented with solvents and procedures that cleaned without using standard water washing.

In that sense, when people ask “who invented dry cleaning?” , a strong, historically grounded answer is: Thomas L. Jennings, with his patented “dry scouring” process in 1821.

The “Father of Modern Dry Cleaning”: Jean-Baptiste Jolly

You’ll also see another name come up a lot: Jean-Baptiste Jolly , a French textile manufacturer.

  • In the mid‑19th century, Jolly noticed that when lamp oil or a petroleum-based solvent spilled on a dirty tablecloth, the stains disappeared after it dried.
  • He experimented further, soaking entire fabrics in these solvents, and realized he could clean garments effectively without traditional water washing.
  • Jolly then opened what is often described as the first modern dry-cleaning shop in Paris, helping commercialize and popularize the service on a larger scale.

Because of this, Jolly is frequently called the “father of modern dry cleaning” , even though Jennings’ invention came earlier and was already laying the technical foundation.

How To Reconcile the Two Names

Historically, you’ll see both names associated with the question “who invented dry cleaning,” but they refer to slightly different “firsts”:

  • Invented and patented an early dry-cleaning process: Thomas L. Jennings (1821, “dry scouring,” United States).
  • Popularized the modern commercial service in Europe: Jean-Baptiste Jolly (mid‑1800s, petroleum-solvent method, France).

A useful way to think about it:

  • If you’re focusing on invention and the first patent , the answer is Thomas L. Jennings.
  • If you’re focusing on the first big commercial “dry cleaner” shop and widespread adoption in Europe , Jean-Baptiste Jolly is the key figure.

Both men shaped what we now recognize as dry cleaning, but Jennings’ work predates Jolly’s and is especially significant for both technological and social reasons.

TL;DR:

  • Inventor with the first known dry-cleaning patent: Thomas L. Jennings (1821, “dry scouring”).
  • Early commercial pioneer of modern dry cleaning in Europe: Jean-Baptiste Jolly (mid‑19th century, petroleum-based solvent cleaning in France).
