Bethlehem Steel, once the backbone of American industry, was a powerhouse in the 20th century, producing steel for iconic structures like the Golden Gate Bridge and the Empire State Building. Founded in 1857, it grew to dominate the U.S. steel market during the two World Wars, supplying vital materials for the war effort. However, working conditions at the massive steelworks were grueling, with relentless heat, extreme danger, and long hours that took a toll on workers' bodies and minds. Many Americans can trace their family history to this industrial giant, with countless grandfathers enduring the harsh realities of the steel mills to provide for their families. The company’s collapse in the late 20th century marked the end of an era for American manufacturing, leaving behind a legacy of innovation and hardship.
