Home County of Allison Mayfield, Conservationist
Sherman, Grayson County, Texas
Marker Inscription
Opened law practice here, 1884. Became an assistant attorney general of Texas, 1893. Won election, 1897, to Railroad Commission; served 26 years -- 16 years as chairman. The commission had been created in 1891 to regulate shipping rates and practices. In his term as chairman, oil and gas regulation -- a major responsibility -- began with jurisdiction over pipelines, 1917. In 1919 the Legislature made the commission responsible for conservation of oil and gas. In the 1920s proration began. Complete regulation came in the 1930s with the 1,700,000-barrel-a-day production in East Texas. Backed by Texas Rangers, the commission closed the field until conservation rules could be revised. Commission policies were acclaimed when in World War II Texas was able to supply the allies with great stores of oil necessary for victory. The commission's goal is to prevent waste and protect oil and gas reserves by orderly regulation of exploration, production and transportation. Such men as Chairman Mayfield set high ethical standards that have continued in the commission, causing it to merit the confidence of the people and of the petroleum industry.

The Story
Allison Mayfield opened a law practice in Sherman in 1884 and rose to the Texas Railroad Commission in 1897, where he served 26 years, 16 of them as chairman. Created in 1891 to regulate shipping rates, the commission under his leadership took on the far larger task of conserving oil and gas — overseeing pipelines, proration, and, in the 1930s, the vast East Texas field. His insistence on orderly regulation helped Texas flood the Allies with oil during World War II.
Why it matters
Mayfield helped forge the conservation-minded oil-and-gas regulation that made Texas the energy powerhouse behind twentieth-century America.
The story behind this marker
AI contextThe era
When Allison Mayfield hung out his lawyer's shingle in Sherman in 1884, North Texas was changing fast. Railroads were stitching the state together and linking its farms and towns to national markets. Sherman, the seat of Grayson County near the Red River, was a busy commercial town riding that wave.
With the railroads came frustration. Farmers and merchants across the country complained that rail companies charged whatever they liked, favored some shippers over others and held entire communities hostage to their rates. In Texas, that anger helped create the Railroad Commission in 1891, a state agency with the power to regulate shipping rates and practices.
No one at the time could have guessed what the commission would become. In the 1890s, oil was still a minor part of the Texas economy. Then, in the early twentieth century, great oil discoveries transformed the state. Petroleum moved from a curiosity to one of the most valuable resources on earth, and somebody had to decide how it would be produced, piped and protected.
That somebody, it turned out, was the agency built to watch over the railroads. Mayfield's long career spans exactly this transition, from an age of rails and cotton to the beginning of the age of oil.
People & events
Allison Mayfield's path ran from a local law office to the state's most consequential regulatory body. After practicing law in Sherman, he became an assistant attorney general of Texas in 1893. Four years later, in 1897, voters elected him to the Railroad Commission. He would serve there for 26 years, and for 16 of them he was its chairman.
During his chairmanship, the commission's work began to shift from railroads toward oil and gas. In 1917 it gained jurisdiction over pipelines, the arteries that carried crude from the fields. In 1919, the Legislature handed it a much bigger responsibility: conserving the state's oil and gas. That was a new idea for an industry that had often operated on the rule of capture, drilling as fast as possible before a neighbor could drain the same pool.
The marker traces how that mission grew after the foundation was laid. Proration, limiting how much each well could produce, began in the 1920s. Then came the gigantic East Texas field in the 1930s, pouring out around 1,700,000 barrels a day. Prices collapsed and the field was being wasted. Backed by the Texas Rangers, the commission shut the field down until it could revise its conservation rules, a dramatic moment that showed how seriously the state took the job.
It is worth being precise: much of that 1930s drama came after Mayfield's own years on the commission. His legacy lies in the groundwork, and in what the marker calls the high ethical standards he helped set, a tradition of trust that later commissioners carried forward when the stakes became enormous.
Its place in the American story
The Texas Railroad Commission became one of the most powerful energy regulators in the world. For much of the twentieth century, its decisions about how much Texas wells could produce helped shape oil prices far beyond the state's borders. A small agency born to settle arguments over freight rates ended up with a hand on the valve of the American economy.
The conservation idea mattered nationally, too. Unrestrained drilling could damage underground reservoirs and leave much of the oil stranded forever. By regulating production, Texas aimed to prevent waste and keep reserves available for the long run. That approach proved its worth in World War II, when, as the marker notes, Texas was able to supply the Allies with great stores of oil essential to victory. Fuel powered the ships, planes and tanks that won the war.
Mayfield's story also illustrates a larger American theme of the Progressive Era: the belief that government, run honestly and competently, could tame powerful industries in the public interest. Railroad regulation and resource conservation were both part of that movement.
From a law office in Sherman to decisions that echoed around the world, his career connects a small North Texas town to the rise of the United States as an energy superpower.
If you visit
Sherman is a pleasant stop in North Texas, just south of the Red River and the Oklahoma border. The historic downtown around the county courthouse gives a sense of the busy commercial town where a young lawyer could launch a career in the 1880s.
When you find this marker, take a moment to connect it with the landscape of Texas oil. There are no derricks here; Sherman is not an oil town. That is part of what makes the story interesting. The man who helped steer the regulation of Texas petroleum came from a place defined by courts, railroads and commerce, not by gushers.
The marker is part of a commemorative series on the Texas Railroad Commission, erected in cooperation with the Abell-Hanger Foundation in 1966. If you enjoy following threads across a state, keep an eye out for related markers honoring other commissioners as you travel.
Sherman pairs well with a drive through the Red River valley or a longer trip east toward the old East Texas oil fields, where you can see the country whose enormous production tested the commission Mayfield helped build.

Dannel Funeral Home
Sherman, TX
Trained in mortuary science in Chicago, John C. Dannel bought the Sherman Undertaking Company and by 1913 had moved his parlor to the courthouse square. When he introduced the area's first motorized hearse in 1917, the local livery stable sued him—a public feud he ultimately won in the newspapers and the courts. In 1923 he commissioned one of the region's earliest purpose-built funeral homes, and the business carried on through four generations of the Dannel family.
Washington Iron Works Inc.
Sherman, TX
After two horseback scouting trips from Quincy, Illinois in 1875, blacksmith Solon Totten moved his family to Sherman to serve the stage lines running out of town. With his brother Levi he opened Totten Bros. Blacksmith in 1876, building and repairing wheels for freight wagons and stagecoaches; renamed Washington Iron Works in 1881, the firm made gun-barrel molds during World War II and grew into a global supplier for oil, gas, and power industries. It is the oldest industry in Sherman.
First Texas Interurban
Sherman-Denison, TX
At the dawn of the twentieth century, electric interurban trolleys knit Texas towns together with fast, frequent service, and the very first such line ran right here between Sherman and Denison. Founded in 1900 and opened in May 1901, the Denison and Sherman Railway built a power plant, car barn, and even a recreational lake for its excursion trains. Merged into ever-larger systems that became the Texas Electric Railway, the interurbans thrived until the automobile pushed them into decline, and the last car passed this spot on the final day of 1948.
Forest Park
Denison, TX
Denison established Forest Park in 1872, the same year the town was founded as a terminus of the Missouri, Kansas & Texas ("Katy") Railroad, when Robert S. Stevens donated six acres on the condition it stay a public park forever. The park hosted the town's first civic celebrations and took its name from the woods that once covered it. During the bitter 1922 nationwide railroad shopmen's strike, the Texas National Guard pitched a tent city here — Camp Ellis — as hundreds of arrests were made among some 1,400 Katy workers.
