Warren, O. - I found my way into a Facebook group for Copperweld Steel retirees, where my grandpa worked for 33 years. He was hired in 1946, not long after he came home from fighting in Europe with a theater medal with five bronze campaign stars on it (fought in Normandy, Northern France, Rhineland and two other major battles) and a beautiful Scottish war bride, who was a nurse in the British Army when they met.
I posted a photo of his original ID badge in the group, and other people began to post their father's or grandfather's badges. Several of these guys worked at Copperweld also, they had followed their fathers into the mill much like my uncle did with my grandpa. There is some great history in the photos below.
The first two digits on the badge represent the department. In my grandpa's case, 17 means the 35" mill department. The second series of digits is your hire number, meaning my gramps was the 4,610th person hired on.
Mr. Desantis also worked in the 35" mill complex. I am told he knew my grandpa well. He was hired much earlier, and actually rolled the first heat of steel in 1939. He and a man named Vic Masio were the only local boys, the rest of the crew was from Canton or Massilon, and were brought down to start up the mill.
