Ford defense-production executive · 1881–1968
Charles E. Sorensen
Sorensen oversaw Ford's wartime defense contracts at the executive level; Dale Roeder led the hands-on Pygmy engineering work.
“"Cast Iron Charlie" ran the war-production empire above the Jeep, not the drafting table underneath it — a distinction most retellings collapse into one name.”
Two names, two roles
Ford's 1940 Pygmy effort gets attached to two different names, and they describe two different jobs. Dale Roeder was the hands-on engineering team leader: his team tuned Ford's tractor-derived four-cylinder from 30 to the required 40 bhp and designed the Pygmy's genuinely influential front sheet metal — all lighting fused behind a single flat grille grate under a wide horizontal hood, the packaging idea that got adopted into the production MB.
"Cast Iron Charlie"
Sorensen was Ford's VP during WWII, responsible for all of Ford's defense contracts: the Jeep (GPW), aircraft engines, and the enormous B-24 Liberator bomber program at Willow Run. He oversaw the Jeep effort at the executive level but did not design it.
A memoir with an agenda
His 1956 memoir, "My Forty Years with Ford", is a notable primary source and a deliberate challenge to the Henry-Ford-as-sole-genius mythology — a first-person account with its own agenda, since Sorensen left Ford in conflict with the family late in his tenure.
