Black History

Ellen F. Eglin, Almost Unknown

During an April 1890 interview with Woman Inventor, a short-lived publication that brought attention to women inventors and the issues they faced, Ellen F. Eglin spoke of her fears. “I am Black and if it was known that a Negro woman patented the invention, white ladies would not buy the wringer. I was afraid to be known because of my color in having it introduced into the market. That is the only reason.”

The world of inventions has historically been dominated by men. This holds true especially for patented inventions. More than 5 million patents have been issued in the United States since 1790. Among them, the mothers of invention are barely represented.

Ellen Eglin (before 1849–after 1890) worked as a housekeeper and washwoman during a time when clothing was washed by hand and hung outdoors to dry. Wringing the water from garments and bedding could be slow, heavy work, making the days long, and Eglin sought efficiency.

In 1888, Eglin invented a clothes wringer, making the job of hanging and drying easier. The invention was an improvement to existing clothes wringers, as the speed of the rollers could be increased or decreased “by a suitable system of spur-gearing.” Clothing and heavier bedding could then be washed and dried faster by first feeding them through two rollers to wring out the water.

Despite the need for the invention and its potential success of being marketed across the country, Eglin chose to step back. For $18 (about $500 today), she sold the patent to Cyrenus Wheeler Jr., who she described as “a white person interested in manufacturing the product.”

During an April 1890 interview with Woman Inventor, a short-lived publication that brought attention to women inventors and the issues they faced, Eglin spoke of her fears. “I am Black and if it was known that a Negro woman patented the invention, white ladies would not buy the wringer. I was afraid to be known because of my color in having it introduced into the market. That is the only reason.”

Beyond the $18 received from Wheeler, Eglin received no further profits from her invention. She would then continue to work as a government worker for most of her life.

Little has been recorded about Eglin’s early life, which is common among many early Black women inventors. She is unlisted in 1850–1870 census records. Later records show her to have been born in Washington, D.C., around 1849, although some other sources disagree, listing her birth in Maryland in 1836. However, 1880 census records list her residence as Massachusetts, but the Washington, D.C., directory lists her there that same year as well.

Later census records show Eglin as either a servant or a charwoman. In 1894, she is listed as a clerk in the census office, but by 1898, she is again listed as a domestic.

Eglin, still hopeful, told Woman Inventor that she was working on another invention, and that she had “money to push it after the patent is issued to me, and the invention will be known as a Black woman’s.”

For reasons unknown, Eglin never went on to register any further inventions.

According to journalist Max Peterson, “Reliance on patent records for understanding the history of invention obscures the contributions of all women, especially African American women.” Had Eglin not spoken to Woman Inventor, she may have remained unknown.

Cassie ‘Mama C’ Lopez Honored as Oakland’s Mother of the Year

Cassandra “Mama C” Lopez, a dedicated parent, teacher, and activist, was honored as Oakland’s Mother of the Year for her unwavering commitment to community and justice.

The City of Oakland recognized Cassandra, “Mama C,” Lopez – parent, teacher, community activist, and justice warrior – as Oakland’s Mother of the Year in a celebration at Oakland’s Morcom Rose Garden on Mother’s Day weekend.

Long recognized as a leader in her community, she was nominated by District 3 City Councilmember Carroll Fife to receive the city’s 73rd annual Mother of the Year award.

Speaking at the crowded ceremony on Saturday, May 9, where Mama C received roses and a proclamation from Mayor Barbara Lee, Fife said she felt honored to nominate Lopez, an “amazing woman – a hell-raising humanitarian, for the energy, the passion, but most of all the love for community” that makes her one of those “exceptional women whose lives, exemplify love, sacrifice, leadership, and unwavering commitment to the family and community they serve.”

Cassie Lopez was born in 1945 to Pauline and Calvin Weaver, a family that had left Florida and Jim Crow for the east side of Detroit. From an early age, she was instilled with a sense of Black awareness, love, and the importance of community in the face of hardships, including poverty, freezing winters, low pay, and slum landlords.

Fifty-five years ago, she married Juan Lopez. The couple has three children and has lived for decades in a neighborhood on the edge of downtown Oakland near Mosswood Park.

Said her husband, Juan, “Mama C has been a selfless mother of our own children, and she also became a teacher. Our home became a second home for many young people. For some, it was refuge from difficult home situations, and for others, a safe place to hang out.

“Throughout the years, Mama C was sometimes a foot soldier and other times a leader, immersed in some of the biggest national and citywide struggles of the day,” Juan said. “But less known to many is the role she played day in and day out where the rubber hits the road.

“For 35 years, she has shepherded the Mosswood Park and Recreation Center – through its good and bad times. If the Center exists (and thrives) today, it has to do with Mama C, working alongside neighbors, center directors, community advisory council, and when necessary, community coalitions, city officials, the religious community, and the labor movement.”

Said Mateenah Floyd-Okanlawon, “I am an old friend of my sister here. We met in 1970 in the sugarcane fields of Cuba, where we were helping the Cuban government harvest their sugar. We have been friends ever since. She has always been someone who does not give in to despair.”

“Cassandra Lopez is a beacon of light, full of compassion. She has dedicated her life to quality education to the poor and working class,” serving for 40 years as a Spanish teacher in Oakland schools, he said.

“She has dedicated her life to speak truth to power, justice to the silent, and as a member of the community, she advocates for programs and resources,” he said.

In her remarks, Mama C recognized the influence and power of all mothers. “Together, we all stand on the backs of our mothers. Mothers play a special role in society. We give when we have almost nothing left to give. We hurt when some people don’t see the hurt and the pain that our families endure. But we keep on moving forward.”

Looking at what African Americans, other people of color and working people face in the country today, she said, “We are deserving of the very best because our hands, our bodies produce the wealth of world, and yet we get the least. We see our country wholesale being stolen away from us, and we are told to grin and bear it. We’re not bearing it; we’re fighting against it.”

Continuing, she said, “There’s enough wealth in this world that there should be no hunger in the world. There should be nobody without a decent place to live. Nobody should be sleeping on the street. Teachers should get the freedom to be creative and tell the stories that exist in this nation that make us strong and great.

“We have a lot to do. We cannot despair. We cannot run. People are learning, and together, collectively, we can do it.”
