“Charles E. Sorensen was hired by Henry Ford in 1905 as a pattern maker, a highly skilled craft of cutting exacting wood patterns from blueprints and creating a three-dimensional representation for foundry castings. "Cast-Iron Charlie," so nicknamed by Henry Ford for his foundry expertise, was master of the River Rouge empire. Fearless and ruthless, he personally was as tough as "Cast-Iron" and not hesitant to display the fact. Though respectful of the Ford family, his loyalty was to Henry, as Edsel had known only too well.”
