The Man Who Fought Standard Oil:

F. Augustus Heinze and the Battle for Butte

Origins and Arrival in Montana

Frederick Augustus Heinze was born on December 5, 1869, in Brooklyn, New York, the son of Otto Heinze, a prosperous German immigrant, and Elizabeth “Lida” Lacey, who was of Irish descent. He received part of his early education in Germany before returning to the United States to study at the Brooklyn Polytechnic Institute and subsequently at Columbia University’s School of Mines, one of the premier engineering programs in the country. Equipped with a rigorous technical education and an inheritance of approximately fifty thousand dollars from his father’s estate, the young Heinze arrived in Butte, Montana, in 1889 at the age of nineteen to take a position as a mining engineer with the Boston and Montana Company (McNelis, Copper King at War 12; King, “The Copper King’s Precipitous Fall”).

The Butte that greeted Heinze in 1889 was already a city of remarkable scale and ambition. Its population had reached roughly twenty-five thousand, and the hill beneath it was widely considered the richest copper deposit in the world. Two established figures — Marcus Daly, founder of the Anaconda Copper Mining Company, and William Andrews Clark, whose banking and mining interests spread across the territory — already dominated the landscape. Heinze, working initially as a surveyor for his employer, spent his early years studying the geology of the district and learning the configuration of ore veins that lay hundreds of feet beneath the surface (Butte-Silver Bow Public Archives, “F. Augustus Heinze”). It was during this period that he grasped what would become the central insight of his career: the subsurface geology of Butte was exceptionally complex, and the federal mining law governing mineral rights contained a provision that a clever operator could use to extraordinary advantage.

Building an Independent Empire

After leaving the Boston and Montana Company, Heinze used his inheritance — supplemented in some accounts by money from a deceased grandmother — to pursue independent ventures (Britannia Mine Museum, “Beyond Britannia — Fritz Heinze”). In 1893, he and his brothers incorporated the Montana Ore Purchasing Company, known widely as the MOP. By 1894, a massive new smelter complex had opened on the south side of the Meaderville district on the eastern edge of the hill. The facility was considerable in its engineering ambition, housing six large reverberatory furnaces, forty-five circular calcining furnaces, and other processing equipment capable of handling ores from independent operators who could not afford, or chose not to use, the Anaconda Company’s facilities. By processing ore for smaller companies at competitive rates, Heinze rapidly made himself a popular and important figure among independent mine owners (Verdigris Project, “Butte, America’s Story Episode 152 — The MOP Smelter”). Within three years of opening, the MOP smelter was reportedly producing two million pounds of copper per month.

Heinze’s next acquisition proved decisive. He purchased the Rarus Mine, a small claim that by some accounts was only a few feet wide at the surface, but whose subsurface ore veins connected to some of the most productive ground on the hill. This was not accidental: Heinze had studied the geology with care and understood that Butte’s ore veins formed an intricate tangle underground, intersecting and overlapping in ways that made surface boundaries almost meaningless as guides to mineral rights. He recognized that the federal Apex Law — the provision stating that a mine operator who held a claim at the point where a vein reached the surface had the right to follow that vein wherever it led underground, even beneath neighboring properties — could be weaponized in the complex geology of Butte (Montana Historical Society, Chapter 10, “Politics and the Copper Kings”).

In 1902, Heinze consolidated his various interests into the United Copper Company, an entity capitalized at eighty million dollars. United Copper’s stock was traded not on the floor of the New York Stock Exchange but on the sidewalk outside — the so-called curb market that would eventually become the American Stock Exchange (King, “The Copper King’s Precipitous Fall”).

The Apex Law Wars

Heinze launched his formal legal offensive in 1898, filing suits against Anaconda, the Boston and Montana Company, and the Butte and Boston Company, all of which were in the process of being absorbed into a new corporate giant (Roger Marjoribanks, “The Copper Wars of Butte”). In 1899, Standard Oil’s senior figures Henry H. Rogers and William Rockefeller completed their acquisition of the major Butte producers and consolidated them under the name Amalgamated Copper Company. With Marcus Daly’s death in 1900, effective control of Montana’s dominant copper enterprise passed entirely to New York financiers with no particular attachment to the state or its workforce. This transition proved politically advantageous for Heinze, who was adept at positioning himself as the defender of Montana workers and independent enterprise against an out-of-state trust (EBSCO Research, “Historic Butte”).

The legal conflict between Heinze’s United Copper and Amalgamated was prolonged, expensive, and often theatrically contentious. By 1902, Heinze employed thirty-seven lawyers to prosecute or defend nearly one hundred separate lawsuits (Montana Historical Society, Chapter 10). His legal advantage derived partly from his influence over two Butte judges whom he had helped elect through lavish political expenditure, and who consistently ruled in his favor. The practical result was that while cases wound their way through the courts, Heinze’s crews worked continuously, extracting ore that he claimed was legally his under the Apex Law from veins that ran beneath Amalgamated’s properties. In 1903, a particularly heated dispute over the Minnie Healey Mine resulted in a court ruling that effectively declared much of Amalgamated’s underground operation in that district illegal (Verdigris Project, “Butte, America’s Story Episode 33 — The Great Shutdown”).

The underground conflict was not merely legal. In some sections of the hill, workers for the two companies encountered each other in the narrow, dark passages beneath the surface. Contemporary accounts describe altercations that included the use of high-pressure water hoses, caustic lime pumped into tunnels, dynamite to collapse passages, and hand-to-hand fighting (Southwest Montana, “The Copper Kings of Butte”). Heinze was eventually fined twenty thousand dollars for contempt of court related to one such incursion, but that sum was insignificant against the value of ore his crews had removed (kids.kiddle.co, “F. Augustus Heinze Facts for Kids”).

The Shutdown and the Courthouse Steps

Amalgamated’s response to the accumulating legal losses came on October 23, 1903, when the company abruptly halted all of its Montana operations — mines, smelters, railroads, and mills — leaving approximately fifteen thousand workers without income as winter approached. The corporate message, delivered through Amalgamated-owned newspapers, was unambiguous: the shutdown would continue until the Montana Legislature passed a change-of-venue law that would allow the company to move its lawsuits out of Butte’s Heinze-friendly courts (Montana Historical Society, Chapter 10; EBSCO Research, “Historic Butte”).

On October 26, 1903, roughly ten thousand people gathered outside the Butte courthouse to demand an explanation. Heinze addressed the crowd from the courthouse steps. He framed the standoff in the most expansive possible terms, characterizing Amalgamated not merely as his corporate adversary but as a threat to ordinary citizens throughout Montana. He warned the assembled workers that if the company destroyed him, it would proceed to cut wages, raise prices in company stores, and ultimately exercise total control over the lives of Montana’s working people (Montana Historical Society, Chapter 10).

The speech was effective. Even those who held Heinze partly responsible for the crisis were persuaded, at least temporarily, that Amalgamated bore the greater share of blame. An independent newspaper, the Lewistown Democrat, editorialized that the company deserved severe censure for throwing workers out of their jobs solely to gain political advantage (Montana Historical Society, Chapter 10). But the economic pressure was overwhelming. Governor Joseph K. Toole called a special legislative session in December 1903. Over Heinze’s protests, the legislature passed a fair-trials bill enabling Amalgamated to move cases to other jurisdictions. The company resumed operations the following day.

The political infrastructure Heinze had constructed in Montana — the friendly judges, the company newspaper (the Butte Reveille), the relationships with legislators — could not withstand the sustained financial pressure Amalgamated was willing to apply. In 1906, after a decade of litigation that had brought him enormous wealth and public celebrity, Heinze sold all of his Butte mining interests to Amalgamated for twenty-five million dollars (EBSCO Research, “Historic Butte”; Montana Historical Society, Chapter 10). He departed for New York City in possession of considerable liquid assets and a reputation, at least in Montana, as the man who had stood up to Standard Oil longer than anyone else.

The Panic of 1907

In New York, Heinze aligned himself with Charles W. Morse, a Wall Street operator who controlled a web of banks and trust companies. Together, the two men held directorships in more than a dozen financial institutions (King, “The Copper King’s Precipitous Fall”). Heinze purchased a controlling interest in the Mercantile National Bank and set up offices at 42 Broadway in Manhattan. His brothers Otto and Arthur opened a brokerage firm in the same building.

The scheme that ultimately destroyed Heinze’s financial position originated with his brother Otto. The plan was a short squeeze: the Heinze family would purchase United Copper stock aggressively, driving up the price, and then demand that short sellers — traders who had borrowed shares they expected to decline — return those shares. Lacking any other source, the short sellers would be forced to buy from the Heinzes at whatever price the family chose to name. Otto believed the family already held control of most outstanding United Copper shares (King, “The Copper King’s Precipitous Fall”). The Heinzes approached Charles T. Barney, president of the Knickerbocker Trust Company — the third-largest trust in New York — to help finance the operation, but Barney declined, warning that the scheme would require more capital than the plan accounted for (Federal Reserve History, “The Panic of 1907”). Despite warnings from Charles Morse that the plan lacked the necessary capital and was too risky without Barney's backing, Otto proceeded regardless.

Beginning on October 14, 1907, Otto began buying United Copper shares heavily, driving the price from approximately thirty-nine dollars to fifty-two dollars per share. The following morning he called in the short sellers. They found ample shares elsewhere, and the price collapsed. Within two days, United Copper had fallen to ten dollars per share (Smithsonian Magazine, “The Copper King’s Precipitous Fall”). Otto’s brokerage was ruined immediately.

The catastrophic collapse triggered immediate runs on institutions tethered to the family's assets. Out west, the State Savings Bank of Butte—owned by Augustus Heinze and holding heavily depreciated United Copper stock as collateral—shut its doors on October 17. The panic instantly spread back east to the Mercantile National Bank and other institutions connected to Heinze and Morse, and within days the contagion reached the Knickerbocker Trust Company, forcing it to suspend operations. Charles Barney subsequently died of a self-inflicted gunshot wound (Federal Reserve History, “The Panic of 1907”).

The contagion spread rapidly. Depositors withdrew funds from banks and trust companies across New York, then across the nation. The Dow Jones Industrial Average fell sharply. J.P. Morgan organized a coalition of leading financiers who pledged their own funds to support solvent institutions, while Treasury Secretary George B. Cortelyou provided twenty-five million dollars in federal liquidity. John D. Rockefeller deposited ten million dollars in a single trust company as a show of confidence (King, “The Copper King’s Precipitous Fall”). The New York Clearing House demanded that Heinze and Morse resign from all banking connections. The broader crisis eventually contributed to congressional consensus on the need for a central banking system, leading to the Federal Reserve Act of 1913 (Fettig, “F. Augustus Heinze of Montana and the Panic of 1907”).

Heinze faced sixteen counts of financial malfeasance. A series of favorable court rulings — in a pattern that recalled his years of legal impunity in Butte — eventually resulted in his complete exoneration by 1909 (Fettig, “F. Augustus Heinze of Montana and the Panic of 1907”).

Return, Decline, and Death

Heinze’s legal exoneration did not restore his financial position or personal circumstances. His business relationships with his brothers had been destroyed by the debacle, and the mining operations he had sold to Amalgamated were gone. He returned to Butte in November 1909 to a reception that astonished observers. Reception committees met his train. A band played. A procession of automobiles wound through town. A crowd attached a rope to his wagon so that supporters could physically help pull it through the streets (Fettig, “F. Augustus Heinze of Montana and the Panic of 1907”). The response reflected enduring loyalty to a figure who had, whatever his methods, fought the Amalgamated trust when no one else would.

Heinze made modest efforts to rebuild. He married actress Bernice Henderson in 1910; the couple had a son, Fritz Augustus Heinze Jr., before divorcing in 1912 (King, “The Copper King’s Precipitous Fall”). He pursued new mining ventures in Idaho and Utah but without the resources or the favorable conditions he had once enjoyed. Those who knew him observed that he had lost much of the energy that had defined his earlier years. United Copper, placed in receivership in 1913, was effectively defunct. The health consequences of years of hard drinking became increasingly apparent. In November 1914, forty-four years old, Heinze died in Saratoga, New York, from a stomach hemorrhage caused by cirrhosis of the liver (Fettig, “F. Augustus Heinze of Montana and the Panic of 1907”).

Assessment and Legacy

Heinze’s career resists straightforward moral categorization. His legal tactics in Butte were widely understood, even by his own contemporaries, to involve manufactured claims, compromised judges, and the exploitation of statutory ambiguity. He used his workers’ loyalty instrumentally, cultivating their affection — by, among other things, implementing an eight-hour workday ahead of the industry standard — in part because their political support gave him leverage against corporate opponents (Southwest Montana, “The Copper Kings of Butte”). The underground conflicts he instigated were dangerous and sometimes lethal for the men who carried out his orders. When it suited his purposes, he accepted the twenty-five-million-dollar settlement from the company he had publicly denounced as the greatest menace in Montana, and walked away.

Yet his decade-long resistance to Amalgamated imposed real costs on a corporation that was in the process of consolidating its control over an entire state’s economy, politics, and press. The fair-trials fight of 1903 demonstrated how completely Amalgamated was willing to use its leverage over Montana’s government and workforce. The editorial from the Lewistown Democrat, calling out corporate coercion by name, was possible in part because Heinze had created the political space in which independent voices could survive. The Butte-Silver Bow Public Archives, which holds materials related to his career, notes that his manipulation of the Apex Law had consequences that extended well beyond Montana, contributing to legal and legislative reconsideration of that provision in federal mining law (Butte-Silver Bow Public Archives, “F. Augustus Heinze”).

After his death, discussion arose in Butte of establishing a scholarship or erecting a monument in his memory. Neither came to pass. His absence from the public landscape of the city he had dominated for a decade is itself informative: a man of his methods and his contradictions does not fit easily into the commemorative tradition. He remains, nonetheless, one of the most consequential figures in Montana’s economic and political history, and the arc of his career — from technical prodigy to copper king to catalyst of a national financial crisis — is without close parallel in the state’s record.
