Who used the technique of horizontal integration to dominate the american steel industry in the late 1800s?

Andrew Carnegie

Andrew Carnegie was a Scottish-American industrialist, business magnate and philanthropist. Carnegie was one of the richest people in history, thanks to his Carnegie Steel Company. The company is one of the earliest examples of vertical integration, as it controlled the mills where steel was made, the mines where the iron ore was extracted, the coal mines that supplied the coal, the ships and railroads that transported it, etc.

the ss was the main organization responsible for the genocidal murder of around six million people of european ethnic minorities, essentially jews, in the holocaust. the members of all its branches committed war crimes and crimes against humanity during the second world war (1939-1945). likewise, the ss were involved in commercial enterprises and exploited the inmates of the concentration camps as slave laborers.

the tortures and assassinations committed by the ss were the result of an ideology developed long before the armed conflict, this ideology was based on the racial supremacy of the germans over the rest.
