William Kelley and Henry Bessemer
William Kelley discovered this process but Henry Bessemer made the patent for it when he independently discovered it after Kelly. The process is called the Bessemer process and it takes the impurities out of iron ore through oxidization. They blow air into the molten iron which helps separate the impurities from the good iron. The Bessemer process allowed for large quantities of high grade steel to be produced quickly at a low cost.
