He resolved at thirty-three to stop accumulating and give everything away, then spent thirty-three more years making the fortune by means he had condemned, and died having built 2,509 libraries with the proceeds.

In December 1868, a thirty-three-year-old man sat down in a room at the St. Nicholas Hotel in New York and wrote a memo to himself. His net worth was $400,000, and with prudent management he could expect $50,000 a year in income for the rest of his life. "Beyond this never earn," he resolved. "Make no effort to increase fortune, but spend the surplus each year for benevolent purposes. Cast aside business forever except for others." Then, as if arguing with the voice that had just spoken: "The amassing of wealth is one of the worst species of idolatry. No idol more debasing than the worship of money." (National Humanities Center, Futility Closet)

The man was Andrew Carnegie. He kept the memo for the rest of his life. He did not stop earning. He spent the next thirty-three years building the largest steel company in the world, and when he sold it in 1901 he became the richest man alive. Then he gave away nearly all of it, 2,509 libraries among the gifts, and died in 1919 with only $30 million left. The memo was not a plan he abandoned. It was a plan he followed, and the contradiction between how he made the money and how he spent it was not a defect in the plan. It was the plan.

The Goose That Lays the Golden Eggs

Carnegie was born in 1835 in Dunfermline, a Scottish town that had once been a medieval capital and was now the center of the damask linen trade. His father, William Carnegie, was a handloom weaver who owned four or five looms. Then the steam-powered looms came, and the trade collapsed. "I began to learn what poverty meant," Carnegie wrote in his Autobiography, published after his death in 1920. "It was burnt into my heart then that my father had to beg for work. And then and there came the resolve that I would cure that when I got to be a man." (Project Gutenberg, PBS)

In May 1848, when Andrew was twelve, the family sold their looms at auction, borrowed twenty pounds from a friend, and sailed for America on a small ship called the Wiscasset. They settled in Allegheny City, across the river from Pittsburgh, in a dark frame house in a neighborhood called Slabtown. Andrew's first job was as a bobbin boy in a cotton mill, changing spools of thread twelve hours a day, six days a week, for $1.20 a week. "I have made millions since," he wrote, "but none of those millions gave me such happiness as my first week's earnings." (Project Gutenberg)

He moved to a bobbin factory, where he tended a steam engine and lay awake at night fearing the boiler would burst. Then, at fifteen, he became a telegraph messenger, memorizing Pittsburgh's street layout and the names and addresses of the city's important men. A superintendent of the Pennsylvania Railroad named Tom Scott noticed the boy and hired him as his personal telegrapher and secretary. Carnegie was learning the largest corporation in America from the inside.

The mechanism that made Carnegie rich was not the one he would later describe. In his Autobiography, he told the story of a mentor who arranged for him to buy shares in a delivery company called Adams Express, and of the morning a white envelope appeared on his desk containing a check for ten dollars, his first dividend. "Eureka!" he wrote. "Here's the goose that lays the golden eggs." (National Humanities Center)

The biographer David Nasaw, working through Carnegie's unpublished papers for his 2006 biography, found the kickback behind the golden eggs. The shares were not a favor from a mentor. They were a payoff. Scott and his superior, J. Edgar Thomson, who ran the Pennsylvania Railroad, were secretly holding stakes in companies the railroad did business with. Carnegie, as Scott's assistant, "functioned instead as a sort of 'bagman,'" holding his superiors' stock along with a few shares for himself. "Capitalizing on insider information to invest in companies that were about to be enriched by lucrative contracts was standard operating procedure for railroad executives," Nasaw writes. It was not illegal at the time. Carnegie judged himself by the standards of his era, and the standards of his era did not forbid it. (Salon)

Carnegie traded up. He invested in a bridge company, a rail mill, a sleeping-car manufacturer, a telegraph company, and a Pennsylvania oil field, each one connected to the railroad that had trained him. He sold his telegraph company to a larger one, exchanged those shares for a stake in Western Union. By his late twenties he had equity in fifteen companies. He resolved, as he wrote in his Autobiography, never to speculate on the stock exchange, calling it "a parasite feeding upon values, creating none." He would own only what he could pay for, and only things he understood. (National Humanities Center)

In 1872, he put all his eggs in one basket. He organized a steel company in Pittsburgh, betting that the railroads would convert from iron to steel rails. He hired Henry Clay Frick to run his coke operations and, later, his mills. Carnegie Steel stayed ahead of competitors by ruthlessly cutting costs, diversifying from rails into structural shapes, and vertically integrating into coke and iron ore. By 1900, its annual profit was $40 million. (Spectator, MUSE)

Let Grass Grow Over Works

The Amalgamated Association of Iron and Steel Workers, a craft union representing the skilled men at Carnegie's Homestead mill, had a three-year contract that expired on June 30, 1892. Frick, whom Carnegie had put in charge, demanded a 22 percent wage cut and proposed to strip many positions from the bargaining unit. The union refused. Frick built a twelve-foot fence topped with barbed wire around the mill, with peepholes for rifles and watchtowers. The workers called it "Fort Frick." (Library of Congress, Wikipedia)

Carnegie had written, in 1886, that workers had a right to negotiate through their unions, that strikes were legitimate trials of strength, and that management should shut down its plants rather than use strikebreakers. Now he sailed for Scotland. On May 4, 1892, he wrote to Frick from England: "We all approve of anything you do, not stopping short of approval of a contest. We are with you to the end." On June 10, he cabled: "Of course you will be asked to confer, and I know you will decline all conferences, as you have taken your stand and have nothing more to say. Of course you will win, and win easier than you suppose." (PBS)

He also wrote: "This is your chance to re-organize the whole affair. Far too many men required by Amalgamated rules." (PBS)

On June 29, Frick locked out 3,800 workers. Two days later, the workers seized the mill and sealed off the town. In the early hours of July 6, two barges carrying three hundred Pinkerton agents floated up the Monongahela River toward the plant. Strikers spotted them in the dark. Thousands of workers and their families gathered on the riverbank with rifles, pistols, dynamite, and a cannon said to have been fired at Antietam. For nearly fourteen hours they traded gunfire with the Pinkertons, who were pinned at the water's edge. When the Pinkertons surrendered and came ashore, the crowd beat them through a gauntlet. Three Pinkertons and seven workers were dead. (New York Review of Books, DPLA)

The next day, July 7, Carnegie cabled from his lodge beside Loch Rannoch: "Cable received. All anxiety gone since you stand firm. Never employ one of these rioters. Let grass grow over works. Must not fail now. You will win easily next trial." (PBS)

Let grass grow over works.

Five days later, the governor of Pennsylvania sent the state militia to Homestead. The mill reopened under military protection with non-union workers. The strike collapsed in November after four months. The union was destroyed. Wages were cut in half. The twelve-hour day was enforced, and every member of the workers' advisory committee was blacklisted for life across the steel industry. (American Heritage, Encyclopedia.com)

Frick cabled Carnegie: "Our victory is now complete and most gratifying. Do not think we will ever have serious labor trouble again. We had to teach our employees a lesson and we have taught them one they will never forget." Carnegie cabled back two words: "Life worth living again." (History.com)

Carnegie told the New York Herald that the news of the violence had come on him "like a thunderbolt in a clear sky." His own cables, which Nasaw would find among his papers a century later, showed that the sky had been clear only because he had ordered the storm. The St. Louis Post-Dispatch reached the verdict that would follow him: "Say what you will of Frick, he is a brave man. Say what you will of Carnegie, he is a coward." (PBS, History.com)

Mark Twain, who knew Carnegie socially, wrote of him in 1907: "He never has any but one theme, himself. He is himself his one darling subject, the only subject he." And then: "I like him; I am ashamed of him; and it is a delight to me to be where he is if he has new material on which to work his vanities." (Salon)

The Man Who Dies Thus Rich Dies Disgraced

Three years before Homestead, in June 1889, Carnegie had published an essay in the North American Review called "Wealth," later reprinted as "The Gospel of Wealth." He argued that the concentration of wealth in the hands of a few was the inevitable price of progress, and that the rich were therefore "the mere agent and trustee for their poorer brethren," bound to administer their surplus revenues during their lifetimes for the general good. Leaving money at death was no virtue, since "no man is to be extolled for doing what he cannot help doing." Heavy estate taxes were "the wisest" form of taxation. The essay ended with the line that would become Carnegie's epitaph: "The man who dies thus rich dies disgraced." (Wikisource, Fordham, Carnegie Corporation)

Nasaw found the 1868 memo, which proved that Carnegie's resolve to give away his fortune predated the Homestead strike by twenty-four years. The philanthropy was not atonement. It was the plan from the beginning, the thing he had promised himself at thirty-three and then spent a quarter-century postponing while he made the money to fund it. The contradiction was structural: he squeezed wages and crushed unions to maximize the fortune he intended to give away, trusting himself better than anyone, including the government, to spend it wisely. (MUSE, Publishers Weekly)

In December 1900, Charles Schwab, the president of Carnegie Steel, gave a speech at a dinner at New York's University Club attended by the banker J. P. Morgan. Schwab outlined a vision for consolidating the American steel industry. Morgan, seated beside him, listened. The next day, Schwab played golf with Carnegie at the Saint Andrew's Golf Club north of the city. Schwab was careful to lose. The following morning, Carnegie wrote a number on a piece of paper and handed it to Schwab: $480 million. Schwab carried it to Morgan, who said, "I accept this price." (Spectator, Bill of Rights Institute)

When the two men shook hands to close the deal, Morgan said: "Congratulations, Mr. Carnegie, you are the richest man in the world." Carnegie later told Morgan: "I made one mistake, Pierpont, when I sold out to you. I should have asked you for a hundred million more than I did." Morgan replied: "You would have got it if you had." (Bill of Rights Institute, ExplorePAHistory)

The sale created U.S. Steel, capitalized at $1.4 billion, the first billion-dollar corporation in history. Federal revenues that year were $587 million. A joke made the rounds: God made the world in 4004 BCE, and it was reorganized in 1901 by J. P. Morgan. (Spectator, ABA Banking Journal)

Carnegie was sixty-five. He had written in the Gospel of Wealth that the rich should live unostentatiously and give away their surplus year by year. Now he set about it. He had begun funding libraries in the 1880s, the first in his birthplace of Dunfermline in 1883. After the sale, the program accelerated. By the time he and his foundation finished, they had spent $56 million building 2,509 public libraries worldwide, 1,681 of them in the United States. In many towns the Carnegie library was the grandest building on the street. (Carnegie Corporation, NPS, Wikipedia)

When Carnegie gave a library to Dunfermline, he learned that his father had been one of three weavers who had donated their personal book collections to the town's first free public library in 1808. "I have never heard of a lineage for which I would exchange that of the library-founding weaver," Carnegie said. "He founded the first library in Dunfermline, his native town, and his son was privileged to found the last." (Carnegie Corporation)

The libraries were his largest expenditure, but not his only one. He founded the Carnegie Institution for Science, the Carnegie Endowment for International Peace, the Carnegie Foundation for the Advancement of Teaching (which created TIAA-CREF, the pension system for college professors), the Carnegie Hero Fund, and the Carnegie Corporation of New York, still one of the largest philanthropic foundations in the country. He gave $22 million to the Carnegie Institute in Pittsburgh, $10 million to the Endowment for International Peace, $6 million for church organs. He insisted that communities provide the land and commit tax dollars to maintain the libraries he built, so that his gifts would not create dependence. (History.com, NPS)

His last great cause was peace. He believed that international arbitration could prevent war, and he spent years lobbying presidents and prime ministers, building the Peace Palace at The Hague, and endowing foundations to promote disarmament. In 1914, he declared himself "strong in the faith that international Peace was soon to prevail." Then the First World War began. Carnegie fell silent. He stopped reading the newspapers. His friends were convinced he had suffered a nervous breakdown, brought on by the failure of everything he had worked for in the last decade of his life. (Carnegie Medal of Philanthropy)

On November 10, 1918, the day before the armistice, he took up his pen for the last time and wrote to President Wilson: "Now that the world war seems practically at an end I cannot refrain from sending you my heartfelt congratulations upon the great share you have had in bringing about its successful conclusion. The Palace of Peace at the Hague would, I think, be the fitting place for dispassionate discussion regarding the destiny of the conquered nations." (Carnegie Medal of Philanthropy)

He died nine months later, on August 11, 1919, at his estate in Lenox, Massachusetts, of bronchial pneumonia. He had given away $350,695,653. The last $30 million went to foundations, charities, and pensioners after his death. (Wikipedia, History.com)

The man who wrote "The man who dies thus rich dies disgraced" came as close as anyone ever has to dying poor on purpose. The man who wired "Let grass grow over works" from a Scottish castle built 2,509 libraries for the people he would not rehire. He did not see the contradiction. He saw a single life, organized around a memo he wrote at thirty-three, in which the making and the giving were the same project, and the workers at Homestead were the cost of the project, and the libraries were the point.
