In 1901, Carnegie was 66 years of age and considering retirement. He reformed his enterprises into conventional joint stock corporations as preparation for this. John Pierpont Morgan was a banker and America's most important financial deal maker. He had observed how efficiently Carnegie produced profits. He envisioned an integrated steel industry that would cut costs, lower prices to consumers, produce in greater quantities and raise wages to workers. To this end, he needed to buy out Carnegie and several other major producers and integrate them into one company, thereby eliminating duplication and waste. He concluded negotiations on March 2, 1901, and formed the United States Steel Corporation. It was the first corporation in the world with a market capitalization over $1 billion.
