When public life becomes difficult, Letitia Plummer opens a box of old letters.
She calls it her “God box.” Inside are the words her grandmother, Letitia Washington Plummer, wrote to her over the years—the private counsel of the woman she describes as her North Star. Plummer now lives in the house where her grandmother lived. She says the energy is still there.
During her Black House interview, a portrait of her grandmother was brought into the room. It captured a moment from Plummer’s first City Council inauguration: the elder Letitia looking at her name on the dais. The candidate who prides herself on composure could not hold the emotion back.
“If there’s a moment I have a hard time, I’ll go back to letters that she wrote me.”
The educator behind the letters
Letitia Washington Plummer was born in 1922 and graduated from Tillotson College in 1942 with a major in chemistry and a minor in mathematics. She taught and served as a guidance counselor at Houston’s Wheatley High School, then was promoted in 1963 to executive director of guidance and counseling for Houston Independent School District.
Former students remembered a small woman—about five-foot-two—whose presence filled a classroom. Her authority did not need volume. Plummer recalls her as the family matriarch: elegant, exacting, and deeply invested in pushing the people around her forward.
When Plummer won her first City Council race, she asked her three sons whether their great-grandmother could escort her across the stage. The sons said yes: they would be there for future milestones; she might not. The photograph on the dais preserved what the gesture meant. One Letitia had spent a career guiding Houston’s children. Another had arrived at the table where Houston’s decisions are made.
A courthouse story in the family tree
The “Judge Plummer” name also reaches back to her grandfather, Matthew W. Plummer Sr. A member of the first graduating class of the law school created at Texas Southern University in 1949, he became the first Black investigator in the Harris County District Attorney’s Office and later a judge of the 133rd Civil District Court.
In 1953, he and three companions attempted to eat at the Harris County Courthouse cafeteria. The manager removed food from their trays and told them the restaurant would not serve Black people. They went to court. The resulting federal case challenged segregation in the building that represented county law itself.
The Houston Lawyers Association, which Plummer helped found, credits him with filing the suit to desegregate the cafeteria. The episode makes his granddaughter’s pursuit of the county’s highest executive office feel less like an isolated first and more like a return to contested ground.
Legacy is not destiny
Political profiles often use family history as an origin myth, turning ancestors into evidence that the next generation was inevitable. Plummer’s account is more interesting because it leaves room for doubt. She ran for Congress and lost. She raised children, ran a dental practice, and entered politics without having planned a lifetime in it. She has been underestimated often enough that it became a recurring theme of the interview.
The letters do not guarantee an outcome. They remind her how to meet uncertainty.
That distinction matters. A family legacy is not a credential voters must accept. It is a set of obligations the descendant must decide whether to carry: education as liberation, the law as a place worth contesting, service as something measured beyond a title.
Why private objects matter in public life
Every public figure develops an armor—a practiced answer, a stage presence, a way to absorb criticism without showing the bruise. The God box represents a different kind of protection. It does not harden Plummer. It reconnects her to a voice that knew her before the campaigns and believed in her without a poll.
In that sense, the box is not nostalgia. It is an accountability mechanism. The letters force a leader to ask whether the person she is becoming would be recognizable to the people whose sacrifices made the opportunity possible.
Houston history lives in institutions, archives, and court opinions. It also lives in family homes—in photographs, stories repeated at dinner, and handwriting saved because someone knew a future day would require it. Plummer’s box carries both kinds of history: the intimate encouragement of a grandmother and the unfinished civic work of a city.
