Early Life and Education

Andrew Carnegie was born in Dunfermline, Scotland, on Nov. 25, 1835. His parents were in the weaving and sewing trade. Never well off, the family saw their meager income dry up as the invention of power looms took over the industry. When Carnegie was 12, the family moved to the United States in search of better opportunities, which was something young Andrew had a knack for doing.

Carnegie worked at a cotton mill in Allegheny, Pennsylvania (now Pittsburgh), before moving on to a job as a telegraph messenger. Carnegie made up for his lack of formal education with self-study by reading and teaching himself to translate telegraph signals by ear. This latter ability was the source of Carnegie's next promotion to a clerk at the telegraph office, and then to telegraph operator at the age of 17.

Carnegie's able mind and charm advanced him quickly up the ranks of the railroad until he found himself serving as the secretary for the Pennsylvania Railroad superintendent, Thomas A. Scott. Under Scott's tutelage, he learned valuable lessons about management and investment.

Carnegie began investing in railroad companies and the industries that supported them and by 1863, he made thousands of dollars a year from dividends. When Scott left the railroad to form the Keystone Bridge Co., Carnegie took over his post as superintendent. In 1865, Carnegie joined his mentor at Keystone and helped mold the successful company.

Notable Accomplishments

Carnegie's investments and partnerships gave him a controlling interest in several diverse businesses. He owned sleeping cars used in the railroad, a portion of Keystone, several iron works supplying Keystone, an oil company, and a steel-rolling mill. Carnegie thought iron would be the base for tying together his businesses, and he consolidated his ownership by vertical integration.

Carnegie bought his biggest competitor, Homestead Works, and a controlling interest in Henry Frick's coke empire. Coke was essential to the steelmaking process, and Frick owned a lot of it. Although the two were very different men (Carnegie was charming and jovial whereas Frick was hard and taciturn), Carnegie saw that Frick had the ability to take over the daily operations of his considerable empire. In 1892, Carnegie combined his companies into one Carnegie Steel Co. and named Frick the chair.

Frick was staunchly anti-union, and the Homestead plant went on strike the very same year he became chair. Steel prices dropped and the cost-conscious Frick wanted to reduce wages to maintain a profit. The union disagreed and a lockout ensued. Carnegie was out of the country, and Frick was determined to break the strike rather than give in to the demands—something Carnegie often did. Frick brought in guards from the Pinkerton Detective Agency to protect non-union workers who were brought in to reopen the plant.

About a dozen people were killed in a fight between the strikers and guards. The militia was called in and the mill went back into operation with non-union workers, but the fight continued. An assassin, unrelated to the union, shot and stabbed Frick a week into the hostilities. He not only survived but bound up his own wounds and finished his workday. Seeing what they were up against, the union folded and accepted reduced wages to get back their jobs. The Homestead strike marred Carnegie's image because many felt he had supported Frick throughout by silent consent.

Carnegie's mills had some of the most modern inventory and cost controls of that time. His management team included Charles M. Schwab, who later became famous as the head of Bethlehem Steel.

Wealth and Philanthropy


On one of his trips to raise capital by selling bonds to European investors, Carnegie noticed the demand for steel was growing and might outpace that of iron. He changed his strategy and began to focus on steel holdings in 1873. Carnegie and his partners focused on building new mills with modern innovations that would out-produce the competition. It was around this time that Carnegie created two basic business rules to guide him:

  • Profits would take care of themselves if costs were carefully monitored
  • The presence of gifted managers was worth more than the actual mills they ran

His mills ran more efficiently than the competition, so he was in the best position to buy when the economy hit a six-year slump in 1873. He snapped up competing mills and companies on other levels of production. He renovated the older mills up to modern standards and was back to outproducing and outearning his remaining competitors when the economy recovered.

The economy hit another rut in 1883 and Carnegie made two acquisitions that would both cement his empire and harm his reputation. Contrarian investors find value in the worst market conditions.

In 1901, Carnegie was given the chance to make good on his word when he sold his company for $480 million to a group of investors headed by J.P. Morgan. Carnegie Steel became the centerpiece of U.S. Steel, a trust controlling 70% of the country's steel production. Carnegie began his philanthropic phase with one of the world's largest personal fortunes.


Carnegie began to focus on writing and philanthropy after the Homestead strike. In 1889, he wrote an article called "The Gospel of Wealth" in which he stated that an industrialist's life should have two phases: One where he accumulates as much wealth as he can, and another where he gives it all away to benefit society.

From 1901 until his death in 1919, Carnegie gave away the modern equivalent of billions of dollars. Perhaps remembering his trouble getting books as a youth, he funded over 2,500 public libraries in the U.S. and abroad—all bearing the Carnegie name. He also financed Carnegie Hall, Carnegie Mellon University, The Carnegie Institution of Washington, The Carnegie Hero Fund Commission, The Carnegie Foundation for the Advancement of Teaching, The Carnegie Foundation, and so on.


Although perhaps a little too fond of his own name, Carnegie shared the stage with John D. Rockefeller as a new breed of industrialist, driven to build a fortune only to give it away. Even now, very few extremely wealthy people disperse their entire fortunes.

Carnegie was able to replace his image as one of the hard-nosed robber barons with that of a modern-day Santa Claus—an image reinforced by his white beard and twinkling eyes. His considerable business and investment expertise may be forgotten over time, but thanks to his philanthropy, his name will not be.

He is also commonly referred to as a pacifist and spent millions to help end World War I. This included supporting the establishment of the Peace Palace in The Hague in 1903 and giving $10 million to start the Carnegie Endowment for International Peace in 1910.

Personal Life

Andrew Carnegie lived as a bachelor for most of his life. That changed when he was in his early-50s. He married Louise Whitfield a year after his mother died. The two signed a prenuptial agreement that stated Carnegie would give away the vast majority of his fortune during his lifetime in exchange for an annual income of $20,000 that would go to Louise. The couple had one child, Margaret, who was born in 1897. Andrew Carnegie died in August 1919. Margaret continued her father's philanthropic legacy. She died in 1990.
