Steel was first used in the 13th century BC. In 1740 crucible steel technique was developed by Benjamin Huntsman. In 1856 Henry Bessemer developed the "basic oxygen converter" to make steel. Andrew Carnegie didn't really improve the production, he knew how to invest his money and he did it in the steel industry. He used Bessemer methods on a very wide scale and he also used his money and influence to control the manufacturing of steel.
Technology has helped to improve industry, and has helped to make common items cheaper and more available for use. It has made life as we know it different, faster, and much cheaper.
