John B. Tytus, Jr’s invention made a significant impact on steel production. He grew up in Middletown and worked in his fathers’s paper mill. When he started to work for the American Rolling Mill, he thought that the method of rolling paper could be applied to metal. In 1927, after 3 years of trial, sheet steel passed smoothly through numerous rollers in the desired thickness and width. This invention revolutionized steel making and made possible the automobile and appliance industries of today.
