Andrew Carnegie

Andrew Carnegie was born in Dunfermline, Scotland.(November 25, 1835 – August 11, 1919) He and his family migrated to United States in his early age. He was always recognized as the second richest man after John D. Rockfeller.
Coincidentally, Carnegie discovered the way to create steel, and then he built Pittsburgh's Carnegie Steel Company. He combined some other steel factories and dominated the U.S. steel. This was a new kind of business management method, horizontal integration. At that time, steel was mostly used in building architecture. Some of the buildings in New York nowadays were made of Carnegie's steel. Telegraph was commonly used at that time as well, because telegraph required steel. As a result, communication between people expanded. A lot of other transportations and communication tools were made of Carnegie's steel.
Carnegie earned a lot of money and he got capital to expand his business then. Therefore, he built all kind of business. For example, he wanted to have a paper factory; so he bought the vertical production line of making paper. 
In my opinion, Andrew was a great guy who created 2 kinds of business management methods. Horizontal Integration brought a lot of advantages to the busines, because it dominated the entire business and earned all of the money from it. Vertical Integration was also a intelligent business management method, because it made you to earn more money because you was not influenced by the price of natural resources and other stuffs. He was also a brilliant guy that discovered the steel and produced it in a large quantities. At that time, Carnegie dominated the whole steel industry and benefited in it. As steel was valuable and rare at that time, he discovered the way to make steel, so he could be a millionaire. He also helped the development of United States as steel helped building a lot of architectures and transportation. Tall buildings and railroads were built, so Carnegie dedicated himself in the beginning of the modern age.
