Born in Dunfermline, Scotland, November 25, 1835. At the age of 13 years, Andrew Carnegie came with his family to the United States in 1848. They settled in Allegheny, Pennsylvania. In hopes to support his family, Carnegie went to work in a factory earning $1.20 a week. The next year he found a job as a telegraph messenger. Hoping to advance his career, he moved up to telegraph operator in 1851. He then took a job at Pennsylvania Railroad in 1853. He worked as an assistant to Thomas Scott, one of the railroads top officials. This will eventually guide Carnegie into a whole different career. Through Scott, he learned more about business investments.

He made many wise choices. And found that his investments, especially those in oil, brought in substantial returns. Carnegie left the railroad business in 1865 to focus on his other interest, the steel industry. Which led to many bridges to be built. Instead of relying on the railroad to transport. And birth of many steel industries. The Keystone Bridge Company is Carnegie's legacy.

Known as Pennsylvania Steel King, Andrew Carnegie passed away August 11, 1919.
