The Welder Who Saved WWII: How Bessie Hamill Solved the Mystery of the Breaking Liberty Ships

Why did America’s WWII Liberty Ships keep breaking in half? This is the unbelievable true story of the industrial miracle that almost became a national disaster. In 1943, Henry Kaiser's revolutionary, fast-built cargo ships—essential to the war effort—were fracturing in calm seas. Over 2,500 ships failed, and 19 broke completely apart. Naval architects were baffled, but the answer came not from an engineer, but from a welder on the night shift: Bessie Hamill. Discover how Hamill's simple, genius insight into welding sequence revealed that massive internal stress (up to 30,000 PSI!) was turning the steel brittle in the freezing North Atlantic. Her discovery led to a total redesign and the creation of the unbreakable Victory Ship, saving the American fleet and proving that speed must be balanced with understanding.
