Amalgamation: Then and Now, from Stefan Jovanovich
"Mergers Would Make AT&T, Comcast World's Most Indebted Companies"
In the last week in February, 1901 J. P. Morgan, Elbert H. Gary, the founder of Federal Steel in Chicago, Charles Schwab, President of Carnegie Steel, and William Henry Moore, owner of National Steel, incorporated United States Steel. On March 2, 1901 they entered into an amalgamation agreement. U.S. Steel's capitalization, most of which was debt, was $1.4B. This was the first combination in history to be a "billion dollar company".
