where did the steel industry first emerge in the united states
History of the steel industry (1850–1970) In 1869 iron was already a major industry, accounting for 6.6% of manufacturing employment and 7.8% of manufacturing output. By then the central figure was Andrew Carnegie,[35] who made Pittsburgh the center of the industry.[36] He sold his operations to US Steel in 1901, which became the world's largest steel corporation for decades.
Industrial Revolution During the late 18th an early 19th centuries when the UK and parts of Western Europe began to industrialise, the US was primarily an agricultural and natural resource producing and processing economy.[149] The building of roads and canals, the introduction of steamboats and the building of railroads were important for handling agricultural and natural resource products in the large and sparsely populated country of the period.[150][151]
