Henry Bessemer
NYSSPE’s Engineer of the Week features Henry Bessemer, born on January 19, 1813 in Hertfordshire, England. He was an inventor and best known for his steel making process which became the most important technique for making steel in the nineteenth century. This way of steel making is known as the Bessemer process and was patented in 1855. It greatly reduces the cost of steel by making it quicker to manufacture and works by blowing oxygen through pig-iron to remove the impurities.
