Barbed Wire

San Antonio, Bexar County, Texas

Marker Inscription

At first called "Devil's Rope" by cowboys, barbed wire was patented in 1873 but found little favor with Texas cattlemen until the late 1870s, when its use and practicality were shown in a sensational demonstration here in San Antonio. Its showman-sponsor was John Ware Gates (1855-1911), who came here as agent for a pioneer wire manufacturer. With permission from city officials, he built a barbed wire corral on the Military Plaza, then went into various resorts of cattlemen and boasted of its strength and economy. Some of the ranchers made bets that the wire would not hold wild cattle. While the scoffers looked on, some longhorns where turned into the corral and prodded to frenzy by burning torches. They charged the fence furiously, but the wire held. The experiment was such a success that for a long time orders exceeded the supply of barbed wire. In later life known as "bet-a-million" Gates, the agent founded or organized several wire and steel plants. About 1901 he also invested in Spindletop oil field and helped develop the city of Port Arthur, Texas. With its sister utility, the windmill, barbed wire led to upgrading of beef cattle and enhancement of nutrition and the quality of human life. (1971)

The Story

Cowboys called it "Devil's Rope," and Texas cattlemen wanted nothing to do with barbed wire until a showman named John Ware Gates staged a dramatic proof on San Antonio's Military Plaza in the late 1870s. He penned frenzied longhorns behind a barbed-wire corral, prodded them with torches, and watched the flimsy-looking fence hold as skeptics lost their bets. Orders soon outran supply, and Gates went on to build wire and steel plants and to invest in the Spindletop oil boom.

Why it matters

Barbed wire ended the open range and remade the American West, turning boundless grassland into fenced property — one of the quiet inventions that reshaped a continent.

The story behind this marker

AI context

The era

In the decades after the Civil War, Texas cattle ranged across vast unfenced grasslands. The open range worked when land seemed endless. Herds grazed freely, roundups sorted out ownership, and cowboys drove cattle to market. But the Great Plains had few trees, and wooden fences were expensive or impossible to build across such distances. Stone walls and hedges were no better.

Barbed wire changed that. Inventors in the Midwest worked on twisted wire with sharp barbs that could hold livestock cheaply, and patents in the early 1870s launched a new industry. The marker gives 1873 as the patent date. Still, many Texas cattlemen were skeptical. They doubted that thin wire could stop a charging longhorn, and plenty of them disliked the idea of fences on what they saw as free range.

San Antonio was a natural place to win them over. It was one of the great cattle towns of Texas, where ranchers gathered to trade, deal, and swap stories. Military Plaza, in the heart of the old city, was a busy public square near the historic Spanish-era center. That made it a natural stage for a show.

People & events

The showman was John Ware Gates, born in 1855, a young salesman who came to San Antonio as agent for a pioneer wire manufacturer. Selling barbed wire to Texans who scorned it as "Devil's Rope" called for more than a sales pitch, and Gates understood that. With permission from city officials, he built a barbed-wire corral right on Military Plaza.

Then he went where the cattlemen gathered and bragged about how strong and cheap his wire was. Some ranchers bet him it would never hold wild cattle. The marker places the demonstration in the late 1870s, and the exact year is told differently in different accounts. What happened next became legend. Longhorns were driven into the corral and stirred into a frenzy with burning torches. They charged the fence again and again, and the wire held.

The skeptics lost their bets, and Gates won an industry. Orders poured in so fast that for a long time demand outran supply. Gates went on to found or organize several wire and steel plants and earned the nickname "Bet-a-Million" Gates for his love of big wagers.

His Texas connection didn't end there. Around 1901 he invested in the Spindletop oil field near Beaumont, the gusher that opened a new era for Texas, and he helped develop the city of Port Arthur on the Gulf Coast.

Its place in the American story

Barbed wire is one of the simple inventions that remade the American West. Cheap fencing let ranchers and farmers enclose land, control breeding, and protect crops from roaming herds. Within a generation the open range of the cattle-drive era gave way to fenced pastures and private property lines across the plains.

The change was not peaceful everywhere. In Texas, conflict over enclosed land, blocked water, and closed roads led to the fence-cutting troubles of the 1880s, and the state eventually made fence cutting a crime. Fencing also hastened the end of the long trail drives and changed life for cowboys, small stockmen, and Native peoples whose lands were already being taken.

The marker also points to a longer view. Together with its "sister utility," the windmill, which brought up water where streams were scarce, barbed wire let ranchers manage and improve their herds. That helped turn rangy longhorns into better beef cattle, a step in how the plains came to feed a growing nation.

If you visit

Military Plaza is still a public square in the heart of downtown San Antonio. As you stand there, try to picture it in the late 1870s: a dusty, crowded square, a strange wire corral, a crowd of doubtful cattlemen, and longhorns crashing into the fence while torches flared. Then picture the moment the wire held and the bets were paid.

The plaza sits in the city's oldest historic district, so you can easily fold this stop into a walking tour. Nearby, look for the Spanish Governor's Palace and San Fernando Cathedral, both reminders that San Antonio's history goes back long before barbed wire, to the Spanish colonial era.

For a larger road trip on the theme, follow the story Gates helped launch. Head toward the Gulf Coast to Beaumont and Port Arthur, where his later fortunes connected to the Spindletop oil boom. Out on any Texas highway you'll also see barbed wire and windmills, the two inventions this marker credits with changing ranch country.

The Stockman Building

San Antonio, TX

Erected in 1867, this San Antonio building housed the workshop of Diedrich Heye, a German-born master leather craftsman who made the saddles, bridles, and harness that outfitted the great age of Texas ranching and trail driving. Among his customers was Captain Richard King of the legendary King Ranch. A century later the building was restored in tribute to its history, its Victorian brick facade, arched windows, and native limestone walls preserved.

Barbed Wire Demonstration

San Antonio, TX

In 1876, salesmen Pete McManus and young John Warne Gates staged a theatrical demonstration in San Antonio's Alamo Plaza, penning thundering longhorns inside a corral of Joseph Glidden's newly patented barbed wire. Skeptical cattlemen watched the flimsy-looking fence hold, then rushed into the Menger Hotel to place orders. Gates, later nicknamed "Bet-A-Million," rode the sale into a fortune and helped found the company that became Texaco.

Halff House

San Antonio, TX

Mayer Halff immigrated to Texas from Alsace-Lorraine in 1850 and, with his brother Solomon, built M. Halff & Brother into a leading San Antonio wholesale dry-goods house while amassing more than a million acres of ranch land and moving into banking. In 1893 he had this ornate Victorian home built, blending Eastlake and Richardsonian Romanesque styles. Threatened by construction of the 1960s HemisFair, the house was moved to preserve it.

Southwestern Bell Telephone Co. Building

San Antonio, TX

Opened at midnight on July 14, 1923, this Colonial Revival building housed Southwestern Bell's Woodlawn telephone exchange, close enough to San Antonio's north-side neighborhoods that its thirty-five operators could walk to work. In 1936 it became home to Tobin Aerial Surveys, founded by WWI combat pilot Edgar Tobin, who pioneered commercial aerial photography and coordinated wartime mapping of much of the United States from these offices. Later serving the United Cerebral Palsy Association, the building was finally converted to residences.
