Thomas L. Jennings, First African American to Receive a Patent

OAKLAND POST — Patents are important official documents as they are used to safeguard one’s inventions. The first U.S. patent was issued in 1790. But it wasn’t until March 3, 1821, that a patent was issued to an African American: Thomas L. Jennings. Jennings, born free in 1791, was awarded the patent for his discovery of a process called dry scouring, also known as dry cleaning. While working as a tailor, he discovered that customers needed a solution for soiled clothing, as certain fabrics were difficult to clean. After experimenting with various cleaning agents and solutions, Jennings soon discovered the successful blend for treatment.

Patents are important official documents as they are used to safeguard one’s inventions. The first U.S. patent was issued in 1790. But it wasn’t until March 3, 1821, that a patent was issued to an African American: Thomas L. Jennings.

Jennings, born free in 1791, was awarded the patent for his discovery of a process called dry scouring, also known as dry cleaning. While working as a tailor, he discovered that customers needed a solution for soiled clothing, as certain fabrics were difficult to clean. After experimenting with various cleaning agents and solutions, Jennings soon discovered the successful blend for treatment.

Jennings’ patent however, was not without controversy. He was a free man and thus was able to gain exclusive rights to his invention and profit from it. But slaves during this time could not patent their own inventions; creations automatically became property of their owners. This regulation in 1793 patent law was based on the legal presumption: “the master is the owner of the fruits of the labor of the slave both manual and intellectual.” Slaves were not citizens and therefore could not own rights to their inventions.

While there were provisions through which an enslaved person could enjoy patent protection, their ability to seek out, receive, and defend a patent was unlikely.

It wasn’t until 1861 that patent rights were extended to enslaved people.

Pat Sluby, a retired U.S. patent examiner and author of “The Inventive Spirit of African Americans,” wrote of Jennings: “He is the earliest [African American receiver of a patent] that we have recorded … This is 44 years before the end of slavery.”

Sluby also described Jennings as: “A very good entrepreneur and businessman.”

It was during his early 20s that Jennings became a tailor. His skills were so admired that people near and far visited his shop to have their clothing altered or custom tailored. This response eventually allowed Jennings to open his own store on Church Street in lower Manhattan, which grew into one of the largest clothing stores in New York City.

Jennings earned a large amount of money as a tailor, and even more with his dry scouring invention. Most of the money funded his abolitionist activities as well as free the rest of his family from slavery.

He became a leader in the abolitionist and civil rights movement in New York City, was a founder and trustee of the Abyssinian Baptist Church, assistant secretary for the First Annual Convention of the People of Color in Philadelphia in 1831, and helped organize the Legal Rights Association in 1855, raising challenges to discrimination, and funding and organizing legal defenses for court cases.

Jennings died in New York City in 1856. Frederick Douglass wrote about his death, noting the importance of the patent Jennings received and that the patent recognized him as a “citizen of the United States,” a designation at the time that shocked many.

On May 4, members of the Farwest Region of Delta Sigma Theta Sorority, Inc., convened at the California State Capitol for the organization’s 23rd annual Delta Days in Sacramento.

The two-day advocacy event brings together chapters from across California to engage directly in the legislative process, connect with lawmakers, and advocate for policies impacting Black communities.

Members of the sorority were honored on the Senate floor by Sen. Laura Richardson (D-San Pedro), who is also a member of Delta Sigma Theta.

Richardson welcomed the Farwest Region during the presentation of a Senate resolution recognizing outgoing Regional Director Kimberly Usher for her leadership and service.

“In addition to the Far West Region, we are led by a fearless leader, regional director Kimberly Usher. She has now served her full term of what’s allowed,” Richardson said. “We are going to be having our regional conference, but we wanted to give it to her here, officially recognizing her service.”

The resolution was co-authored by Richardson and fellow members of the California Legislative Black Caucus (CLBC) and Delta Sigma Theta, Sen. Akilah Weber Pierson (D-San Diego) and Assemblymember Rhodesia Ransom (D-Stockton).

Usher has served in the leadership role since 2022.

“We are founded on sisterhood that is deeply rooted in scholarship, service, and social action,” said Weber Pierson, a member of the Gamma Alpha chapter of Delta Sigma Theta Sorority.

“Today, we continue a legacy of empowering communities and upholding the high cultural, intellectual, and moral standards established by our founders over a century ago,” she added.

OPINION: The Fire of Oakland’s Justin Jones

Jones made headlines three years ago when he was one of a pair of Justins. Along with fellow State Rep. Justin Pearson (D-Memphis), he fought their removal from the state house in Tennessee and won reinstatement. Now, Pearson is running for Congress and Jones is still fighting for all of us.

You may know Tennessee State Rep. Justin Jones (D-Nashville).

He grew up in Oakland and the East Bay. His mother is Filipino. You can tell by his full name Justin Shea Bautista Jones.

His father is African American.

He is fighting for all of us.

Now, Pearson is running for Congress and Jones is still fighting for all of us.

The recent 6-3 Supreme Court decision barring the use of race in drawing congressional districts marks a major turning point in U.S. history.

The decision took away the Voting Rights Act’s power to assure minority voices were both heard and represented.

“What we’re seeing now is this new Jim Crow system in which Black and Brown communities are without voice in our political process,” he told Fredricka Whitfield on CNN last weekend.

“That’s a canary in the coal mine for the rest of the nation. If they come for one of us, they’re coming for all of us, and some of my message to America is that the South is the front line of democracy,” Jones said. “They are dismantling multi-racial democracy here in the South, in states like Tennessee and Louisiana. But they aren’t going to stop here.”

That’s why Jones said we have to start paying attention to the South, and start helping them fight back there,” he said.

“I want to be clear that this terror, this type of system they’re enacting, are the same systems my grandparents told me about who grew up in Tennessee, a system where people like me couldn’t even be in political office. That’s the time they’re bringing us back to and I’m not sounding the alarm to be alarmist. But I am sounding it because we’ve seen this before in our history.”

Jones talked about Reconstruction and about what happened between the end of the 1800s and the beginning of the 1960s, when there was no Black political representation.

It’s a rebellion to keep our democracy going forward, he said.

“Stand with us and help us fight back against this extremist power grab — this racist power grab against our vision of a multi-racial democracy,” Jones added.

“While there is a litigation strategy, it’s important to maintain what he called a “movement strategy” that leads to the largest voter mobilization and registration that has ever been seen in the South,” he encouraged.

In 2026.

“Tennessee is an oppressed state,” Jones said. “It’s a state where one in five Black voters can’t vote because of felony disenfranchisement. It is where you can use a gun permit to vote, but you can’t use a student ID card to vote.

That’s the Asian American African American voice of Justin Jones.

Read his words for inspiration.

On Tuesday, May 12, Oakland honored a towering community figure, William “Bill” Patterson, with the unveiling of a bronze plaque and the renaming of the East Bay Municipal Utility District (EBMUD) boardroom in downtown Oakland.

Board members, family, colleagues, and mentees gathered to reflect on Patterson’s enduring legacy at the meeting.

Patterson, who died in 2025 at the age of 94, was remembered as a tireless advocate, mentor, and public servant whose influence shaped generations across the East Bay.

“This is well deserved,” said Patterson’s cousin, Maria Simon. “He was such a big part of the Oakland community. It’s heartwarming to know he was known by so many people.

“So many credit him with helping them get their first job. It was especially meaningful when he held the Bible for Mayor Barbara Lee’s swearing-in. He truly believed in the goodness of people, in possibilities, and in the power to bring things to fruition.”

Oakland NAACP President Cynthia Adams described Patterson as a father figure. “He took me under his wing,” she said. “This recognition is a very special moment.”

Fellow NAACP member Robert “Bob” Harris echoed that sentiment, recalling Patterson as “a great member of the NAACP and a proud Kappa Alpha Psi man.”

Patterson’s son, William Patterson Jr., reflected on his father’s professional life.

“My father loved his community, and he loved working with EBMUD and spoke highly of his colleagues,” he said, standing alongside cousin Rise Jones Pichon, a former Santa Clara County Superior Court judge.

EBMUD Board President Luz Gómez praised Patterson’s resilience and dedication.

“As his health declined, he would spend half the day in the hospital and still come to our meetings,” she said. “There will never be another like him.”

Activist Cheryl Sudduth highlighted Patterson’s commitment to workforce development and youth empowerment. “He had the vision to bring water careers to students and the next generation,” she said, noting that participants in one of his initiatives received $2,000 stipends.

Sudduth also summed up one of Patterson’s guiding philosophies: “He told me it’s not enough to have a seat at the table. You need to have access to quality resources, the tools to build the table, and the skills to ensure everyone there can contribute. We should be more than a representation; we should reflect determination.”

EBMUD Board Member Andy Katz emphasized the importance of remembrance.

“When you die, you die twice, physically, and then when people stop saying your name,” he said. “By honoring him this way, his name will continue to be spoken for years to come.”

Others in attendance reflected on Patterson’s broad impact.

“It was a joy to watch him accomplish so much,” said EBMUD Board Member Marguerite Young.

Business leader, Delane Sims added that Patterson became a trusted advisor to multiple Oakland mayors.

“We need young people to learn about him so they can become leaders capable of creating meaningful change,” Sims said.

Following public comments, attendees witnessed the unveiling of the bronze plaque in the boardroom foyer, along with signage officially renaming the space in Patterson’s honor.

Born in 1931, Patterson devoted more than seven decades to public service in Oakland and the broader East Bay. Appointed to the EBMUD Board in 1997, he served for 27 years and became its first African American board president. His leadership extended beyond water governance into civil rights, education, and community development.

A three-term president of the Oakland NAACP, Patterson also advised Oakland’s first Black mayor, Lionel Wilson, and played a key role in advancing equity, public health, and environmental justice. He served on the Urban Strategies Council and the Oakland Public Ethics Commission, further shaping public policy.

In 1971, Patterson was a founding director of the Peralta Colleges Foundation, which provides financial assistance and support to students across Berkeley City College, College of Alameda, Laney College, and Merritt College.

In addition, Patterson mentored countless young people through Oakland’s recreation programs, helping guide future leaders and even professional athletes. Though slight in stature, Patterson will always be remembered as a giant of a man.
