On the western outskirts of Sheffield—the Sheffield of 1875—there was a dingy red factory that had seen the bankruptcies of at least three concerns which had been housed within its high walls. In this year it was occupied by the staff of a Mr Wertheimer, who produced nothing that was of commercial value, and was rather secretive about what he hoped to produce at all. He called himself and his partner, known and unknown, "The Silver Steel Company", which, as Baldy said subsequently, was a contradiction in terms.
