Dr. John R. Brinkley
Del Rio, Val Verde County, Texas
Marker Inscription
North Carolina native John R. Brinkley (1885-1942) opened a medical clinic and radio station in Kansas and promoted controversial medical practices, including one that used goat gland implants to increase sexual "pep" in men. He became rich but was criticized by the American Medical Association and the Federal Radio Commission. In 1933, he moved his family to Del Rio, opening a hospital and setting up the powerful radio station XER in Villa Acuña, Mexico. He was a colorful, charitable individual, known for his lavish lifestyle. He buoyed the local economy during the Great Depression and brought much attention to Del Rio. Despite fame and wealth, authorities shut down the Brinkley enterprise in 1938. (2004)

The Story
John R. Brinkley made a fortune peddling dubious cures — most infamously goat-gland surgery marketed to restore men's vigor — and pioneered the use of radio to reach a mass audience. Hounded by the American Medical Association and federal regulators, he relocated to Del Rio in 1933 and beamed his message across the country from a powerful 'border blaster' station just over the line in Mexico. Flamboyant and free-spending, he pumped money into the local economy during the Great Depression before authorities finally shut his operation down in 1938.
Why it matters
Brinkley's border-radio empire helped invent modern broadcast advertising and the medical-huckster celebrity, and stands as a Depression-era case study in the limits of regulating the airwaves.
The story behind this marker
AI contextThe era
The 1920s and '30s were the wild adolescence of American radio. A brand-new medium had put a voice inside millions of living rooms, and no one had quite decided what the rules were — who could broadcast, how powerful a station could be, or what a person was allowed to sell over the air. Into that unsettled space rushed showmen, salesmen, and more than a few outright charlatans.
Medicine was in a similar state of flux. Real science was advancing fast, but the line between doctor and quack was still being drawn, and organizations like the American Medical Association were fighting to define legitimate practice. That left plenty of room for a confident man with a bold claim and a gift for promotion.
Then came the Great Depression, which reshuffled every deck. Ordinary people were desperate — for money, for health, for hope — and a border town like Del Rio, hard against Mexico, sat at the edge of American law in a way that could be turned to advantage. Just across the line, a broadcaster could build a transmitter far more powerful than U.S. rules allowed and beam his voice back across the entire country.
People & events
John R. Brinkley, born in North Carolina in 1885, first made his name — and his fortune — in Kansas, where he ran a clinic and a radio station and promoted a string of controversial treatments. The most notorious involved implanting goat glands to restore men's flagging vigor, a claim as sensational as it was dubious. It made him rich and famous, and it made him enemies: the American Medical Association and the Federal Radio Commission both took aim at his practices.
Run out of Kansas, Brinkley did not retreat — he relocated and doubled down. In 1933 he moved his family to Del Rio, opened a hospital, and set up the enormously powerful station XER just across the river in Villa Acuña, Mexico, beyond the reach of American broadcast regulators. From there his signal blanketed the continent.
He was, by every account, a character — flamboyant, free-spending, and genuinely charitable, cultivating a lavish public image while pumping money into a town gripped by the Depression. For a few years he was Del Rio's great benefactor and its most famous resident. But the reckoning came: in 1938 the authorities finally shut the Brinkley enterprise down, ending one of the strangest careers in American broadcasting.
Its place in the American story
Brinkley matters far beyond Del Rio because he helped invent things we now take for granted. His mastery of radio as a tool for reaching a mass audience — mixing entertainment, folksy persuasion, and relentless salesmanship — anticipated the entire business of broadcast advertising. He understood before almost anyone that a voice on the air could sell almost anything.
His 'border blaster' station is a landmark in a specifically American drama: the struggle to regulate the airwaves. By transmitting from Mexican soil, he exposed exactly how a national border could be used to slip a national rule, and cases like his pushed the United States toward the international agreements and firmer regulation that eventually followed. He is a case study in the limits of the law when technology outruns it.
He is also a distinctly American type — the medical-huckster celebrity, equal parts entertainer, entrepreneur, and cautionary tale. The genuine good he did for a struggling town and the genuine harm in his medical claims are both true at once, which is precisely what makes him unforgettable rather than simply villainous.
If you visit
Del Rio sits right on the border, and to appreciate Brinkley's story you have to feel that geography. Stand here and look toward Mexico, and picture a transmitter just over the line throwing an American voice clear across the country — the whole scheme depended on that thin, crossable boundary.
Let this marker be your invitation to think about a vanished media world: a time before television, when a single powerful radio signal could make one man's voice familiar in living rooms thousands of miles away. It's a story that turns an ordinary border town into the unlikely capital of a national broadcasting empire.
As you explore Del Rio, carry the town's Depression-era memory with you. Brinkley was both a benefactor who spread money through hard times and a promoter of claims that could not stand scrutiny — and holding those two things together is the real reward of the visit. It's a stop that will have you marveling at how strange, and how modern, the recent past can be.

Rocksprings Telephone Company
Rocksprings, TX
In 1898 a local businessman and a Kerrville partner strung a long-distance line across the Hill Country to Rocksprings, installing the town's first telephone in a general store. From crank-handled magneto phones shared by as many as seventeen parties, the enterprise grew into a family-run company that survived the 1927 tornado and converted every exchange to dial service by 1958. A century on, descendants of the founder still sat on its board.
Brinkley Mansion
Del Rio, TX
Built on former canal-irrigated farmland beginning in the early 1930s, this Spanish Eclectic house was bought in 1934 by the notorious "goat-gland doctor" John R. Brinkley and his wife Minnie. The couple enlarged it and adorned the grounds with elaborate water features, a menagerie, flashing colored lights, and loudspeakers wired to an indoor pipe organ, drawing local residents to dance and take in the show. The Brinkley family kept the Del Rio landmark for 46 years.
Val Verde Winery
Del Rio, TX
Frank Qualia left Milan, Italy, and reached the small border town of Del Rio in 1882, planting vineyards and making wine in the old-country style. His Val Verde Winery survived Prohibition and the collapse of Texas's roughly two dozen early wineries to become the state's oldest bonded winery, still cooled by its original 18-inch adobe walls. Generations of the Qualia family have kept it producing.
Old Perry Building
Del Rio, TX
John Perry raised this sturdy building in 1871, before Del Rio itself was even founded, to serve as a general store — reputedly the largest between San Antonio and El Paso. On the thinly settled border it doubled as courthouse, church, Masonic lodge, and post office, the kind of all-purpose hub that frontier towns grew up around. Perry's descendants gave it to the city and county in 1965.
