Did Andrew Carnegie form a trust?

No, Andrew Carnegie did not form a trust in the formal sense. Instead, he built a vast steel empire through vertical integration and strategic acquisitions, culminating in the formation of the Carnegie Steel Company in 1892. However, he did play a significant role in the broader trend of industrial consolidation during the late 19th century, which included trusts formed by other industrialists. Ultimately, Carnegie sold his company to J.P. Morgan in 1901, leading to the creation of U.S. Steel, which functioned as a trust.
