Checking out the Tinbasher Blog this morning and noticed that Paul had posted a link to a History of Steelmaking in NE Ohio
Amongst the companies mentioned was Acme Metals, based in Riverdale . I worked with Acme for a short while and visited their plant in Chicago in the Autumn of 2000.
This got me surfing for more history and I found another link relating to Steelmaking in Rotherham.
If anyone out there has any links to sites with any steelmaking history documents, I would love to hear from you.
