Section 63
Rensselaer Dean Hubbard rose from modest beginnings to become one of the most influential business figures in southern Minnesota during the late nineteenth century. His life was defined by ambition, endurance, and a remarkable instinct for enterprise.
Born to Oliver B. Hubbard and Lavina Chase, farmers of Connecticut ancestry, young Hubbard received only limited formal schooling. At fifteen he left home to work, joining a survey crew employed by the Albany & Susquehanna Railroad. Restless and adventurous, he headed west in the early 1850s, working on a farm in California’s Sacramento Valley and later trying his hand at gold mining along the Humboldt River in Nevada and the Fraser River in British Columbia during the gold excitement of the late 1850s.
By 1859 he had returned east and secured employment as a grocery clerk at $50 per month. His diligence quickly earned promotion to manager at $160 per month — a substantial salary at the time. In January 1863 he attempted to enlist in the Union Army, but a severe attack of pneumonia rendered him unfit for military service. That same year, on April 9, 1863, he married Mary Esther Cook in New York.
In 1866 the couple moved to Corry, Pennsylvania, where Hubbard re-entered the grocery business with $2,000 in capital. Within four years he had accumulated nearly $30,000 — a testament to his discipline and business acumen. Drawn westward once more, he went to California in 1870 intending to organize a bank, but unfavorable financial conditions led him instead to settle in Mankato, Minnesota.
There, Hubbard began the work that would define his legacy. He constructed a warehouse and entered the wheat-buying trade. In March 1872 he helped establish the Mankato Linseed Oil Company, serving as its manager for eleven years. Though the enterprise endured periods of depression, it ultimately succeeded and was sold into a larger trust.
In 1878 Hubbard founded what became his most enduring achievement — the Mankato Milling Company. Serving as president, he guided its evolution through several reorganizations: R. D. Hubbard & Company, the R. D. Hubbard Milling Company (1894), and finally the Hubbard Milling Company (1897). Under his leadership, the firm became one of the largest and most important milling operations in southern Minnesota, processing tens of thousands of bushels of wheat annually. In partnership with George Palmer, he also developed a system of approximately forty grain elevators along the Chicago, St. Paul, Minneapolis & Omaha Railway, creating a vertically integrated agricultural network that tied regional farmers to national markets.
Hubbard’s interests extended beyond milling. He was involved in linseed oil works in both Mankato and Sioux City, invested in ranching operations in Montana, and played a role in organizing banking institutions. Though he served one term on the Mankato City Council and took a keen interest in public improvements, he devoted the greater part of his energy to private enterprise, believing strongly in disciplined business leadership as the engine of civic growth.
Contemporaries described him as possessing pluck, endurance, and rare sagacity. Rising “from poverty to opulence through his own efforts,” he was known to be generous, liberal, and willing to extend financial assistance to those in need. For thirty-five years he remained a central figure in Mankato’s commercial life and was regarded as one of its most progressive citizens.
His first wife, Mary Esther Cook, died in 1877. On October 7, 1878, he married Frances H. “Frank” Griffith in Mankato. He was the father of three surviving children: Jay Hubbard, who continued in the milling business; Katherine Hubbard Ervin; and Mary Esther Hubbard Richter.
In late August 1905, while on a business trip to Chicago and staying at the Auditorium Annex, Hubbard was stricken suddenly and died on the evening of August 29. Early reports suggested cerebral hemorrhage, but a coroner’s examination confirmed death from heart failure due to natural causes. His passing sent shockwaves through Mankato, where he had been a dominant figure in commerce for more than three decades.
His body was returned home for burial in Glenwood Cemetery — a resting place for many of the city’s builders.
From railroad laborer and gold prospector to industrialist and civic leader, Rensselaer Dean Hubbard embodied the drive and confidence of nineteenth-century American enterprise. The businesses he established not only endured but continued to influence the agricultural economy long after his death, securing his place among the foremost architects of Mankato’s growth.
