Before there was a single spangled star or a specific pair of white boots, there was a Tyler, Texas schoolteacher with a legal pad, sketching out what a football sideline could look like. Dee Brock, the founding director who built the Dallas Cowboys Cheerleaders from a volunteer high school pep squad into the prototype for nearly every professional dance team that followed, died in Tyler, Texas, on September 23, 2026, at 96.

Brock grew up in Wright City, in East Texas, and went to school in nearby New London before moving to Dallas, where she worked as a model. Cowboys general manager Tex Schramm first pictured paid models working the sidelines when he approached Brock around 1960. She talked him out of it: models required money, and Schramm did not like to spend it. She proposed something cheaper, and, she believed, better: local high school students who would perform for free, at a salary for herself of about $900 a year. Texas Monthly later credited that swap, made by a schoolteacher rather than an executive, with setting the squad's whole trajectory.

Five years later, Brock pushed the squad past a line few in Dallas were willing to cross. Working with Frances Roberson, a teacher at an all-Black Dallas school, she recruited the group's first Black members, among them Eunice Cicero, then a 16-year-old high school student. By 1971, roughly half the squad was Black, in a city where much of public life remained segregated. Brock described her own effort simply: "I just kept after it. Eventually it happened." Cicero later put it another way: "Had it not been for (Brock's) persistence in having someone of color on the team, it would have perhaps taken even longer," she said, adding that "the kindness that she showed, the encouragement, the warmth to a 16-year-old high school girl, it's amazing what encouraging words, what kindness can do," according to NBC News.

By the early 1970s, Brock and Schramm remade the squad again: raising the minimum age to eighteen, hiring Dallas dance studio owner Texie Waterman as choreographer and cutting her own salary to about $600 a year to help pay for it, and sketching early concepts for the new look on a legal pad, concepts a hired designer, Paula Van Wagoner, would later formalize into the now-famous uniform. The squad that took the field in 1972, in boots, cutoff shorts and a star-spangled midriff top, became the template copied by dance squads across professional and college sports for the next half century. Brock's cheerleaders had already reached Super Bowl V in Miami and Super Bowl VI in New Orleans; she stepped down as director in 1975, after fifteen seasons that carried the squad from a volunteer pep club to a fixture of NFL broadcasts.

Brock's second career ran alongside her first. She held degrees in English, including a master's from the University of North Texas, and taught high school English in the Dallas schools during her early years with the cheerleaders. When El Centro College opened in 1966 as the first campus of what is now Dallas College, and the first community college in Dallas, she helped establish it, continuing to direct the cheerleaders until 1975. She went on to complete a PhD in literature.

The squad's place in American culture eventually reached the Smithsonian. In February 2018, the National Museum of American History accepted a set of Dallas Cowboys Cheerleaders artifacts, including a 1980s game uniform, pom-poms and the squad's original 1977 poster, artifacts of the look Brock had first set in motion decades earlier.

Tyler, her adopted hometown, recognized her much earlier: in 2009, civic groups there honored her at a local women's luncheon, years before the wider country revisited her role in the cheerleaders' history. In June 2022, dozens of current and former cheerleaders gathered at Brock's home in Tyler to mark the squad's 60th anniversary. Director Kelli Finglass presented her with a bejeweled "lifetime achievement" football, and Brock allowed herself a rare moment of pride: "I cannot help but feel a little proud," she told the Longview News-Journal. Weeks later she told a local television interviewer, "I hadn't realized I had made such a good impression, and I'm so happy about that."

Brock's death was announced on social media by Greg Whiteley, director of the Netflix documentary series "America's Sweethearts," who wrote that if the Cowboys ever put a woman in their Ring of Honor, "you'd be hard-pressed to find anyone more deserving than Ms. Dee Brock." Current cheerleaders' director Kelli Finglass said in a statement carried by Yahoo that "Dee's leadership, imagination, and unwavering commitment to excellence shaped far more than a team. She created a standard, a spirit, and a symbol that have inspired generations and earned recognition around the world."

What Brock built outlives the headline that announced her death. The high school volunteers she recruited around a Dallas budget shortfall in 1960 became a squad whose uniform now sits in a Smithsonian display case. The color line she pushed past in 1965 opened a roster that, within six years, matched a demographic reality much of Dallas had not yet accepted. And the community college she helped start in 1966 has educated generations of Dallas students long after the sideline cameras moved on to someone else. Three institutions, one woman, and a legal pad.
