The Legacy of Hugh Glenn and Peter French in Southeastern Oregon

From California Wheat King to Oregon Cattle Baron

Before the town of Frenchglen became a dot on the map, it was the beating heart of a vast and ambitious cattle empire—an enterprise rooted in California ambition and Oregon frontier grit. At the center of it all were two men: Hugh James Glenn and Peter French.

Hugh Glenn: Ambition Takes Root

Born in 1824 in Virginia and raised in Missouri, Hugh Glenn studied medicine and served in the Mexican-American War before chasing opportunity west during the California Gold Rush. Though he didn’t strike it rich in the goldfields, Glenn had a keen sense for business. He bought and sold a livery operation in Sacramento, then returned to California in 1853 with his wife, Nancy, and young family to put down roots as a rancher.

Settling in Jacinto, California, Glenn began buying land—lots of it. Over the next two decades, he amassed over 55,000 acres and became a major wheat grower, earning the nickname “The Wheat King” of California. But Glenn wasn’t content to farm in one state. His ambitions stretched north to Oregon’s open rangelands.

A Young Cowboy with a Big Job

In 1872, Glenn hired a promising 23-year-old horse breaker named Peter French and sent him on an extraordinary assignment: take 1,200 head of Shorthorn cattle and establish a new cattle operation in Oregon’s Blitzen Valley. French set out with a team of vaqueros and made his way into the remote, windswept basin of Harney County. Soon after arriving, French struck a deal with a down-on-his-luck prospector named Porter. French acquired Porter’s small herd of cattle, a “P” brand, and rights to graze on the west slope of Steens Mountain. That modest exchange was the seed of something much larger.

Building the French-Glenn Cattle Empire

French wasted no time expanding the operation. He drained wetlands, irrigated pastures, and fenced off thousands of acres along the Donner und Blitzen River. The newly established P Ranch became the headquarters of a growing cattle empire. By the 1880s, the Glenn holdings in Oregon had expanded dramatically, eventually covering over 140,000 acres—and possibly as much as 200,000. The land was organized into five divisions: the P Ranch, Catlow Valley, Diamond Valley, Happy Valley, and Sod-House. French oversaw the movement of cattle to market, driving herds over 200 miles to the railhead at Winnemucca, Nevada.

In 1883, Peter French married Hugh Glenn’s daughter, Ella—a union that symbolically sealed the partnership between the California wheat tycoon and the Oregon cattleman. But just three weeks after the wedding, tragedy struck: Hugh Glenn was shot and killed by a disgruntled employee on his California ranch.

Power, Water, and Conflict

French took over management of the Oregon operation, now burdened by the Glenn family’s debts. He sold more cattle to cover expenses and, in 1894, became president of the newly incorporated French-Glenn Livestock Company. With headquarters in Chico, California, the company continued to expand its reach across southeastern Oregon. But as the cattle empire grew, so did tensions with local settlers. French’s fences blocked access to grazing land and water—vital resources in the high desert. He became a controversial figure, respected for his business acumen but resented by many homesteaders.

On December 26, 1897, Peter French was shot and killed by a settler who had been denied a road easement across ranch property. His death marked the beginning of the end for the empire he helped build.

A Fading Empire, A Lasting Legacy

After French’s murder, the livestock company began selling off its assets. Over time, the vast rangelands were divided and repurposed. In 1935, the U.S. government purchased the remaining P Ranch property and incorporated it into the Malheur National Wildlife Refuge. Most of the original ranch buildings were lost to time, fire, or demolition by the Civilian Conservation Corps during the 1930s. What remains—now listed on the National Register of Historic Places—serves as a quiet monument to a bold chapter in Oregon’s ranching history.

Meanwhile, the town of Frenchglen carries Peter French’s name, and the Pete French Round Barn still stands nearby—a circular structure once used to train horses through the long winters. These places serve as reminders of a time when ambition rode on horseback and thousands of cattle shaped the destiny of southeastern Oregon.
