3. Deadly Caisson Disease and Underwater Construction

To anchor the Brooklyn Bridge to the bedrock of the East River, builders had to venture into the unknown: the treacherous riverbed itself. The solution was as ingenious as it was dangerous, employing massive, airtight timber chambers called pneumatic caissons. These structures, forced down to the river floor by immense weight, were pumped full of compressed air to keep water out, allowing workers to excavate the mud and sand below. This pioneering method came at a terrible human cost, introducing the world to a mysterious and frightening ailment: caisson disease.

This condition, now known as decompression sickness or "the bends," afflicted those who returned to normal atmospheric pressure too quickly. The nitrogen that had dissolved into their bloodstreams under high pressure would form bubbles, causing excruciating joint pain, paralysis, and even death. This grim reality is one of the most sobering Brooklyn Bridge history facts. Over 100 men suffered from the debilitating illness, with at least 20 losing their lives in the dark, pressurized depths beneath the river.

A Sacrifice That Pushed Medical Science Forward

The suffering was immense, but it was not in vain. The tragedy spurred the first serious medical investigations into decompression sickness, paving the way for safer underwater and high-altitude work for generations to come. The lessons learned in the caissons of the Brooklyn Bridge became the foundation for modern occupational safety protocols.

• Washington Roebling’s Ordeal: The chief engineer himself, Washington Roebling, became a prominent victim. After spending long hours directing work in the caissons, he was struck down by the disease, leaving him partially paralyzed and bedridden for the rest of his life.
• A Catalyst for Safety: The high casualty rate forced engineers and doctors to study the effects of pressure on the human body, leading directly to the development of gradual decompression chambers and stricter time limits for workers in future projects.
• Foundation of Modern Medicine: The medical records and observations from the bridge's construction provided crucial data that helped physicians like Dr. Andrew Smith formalize the understanding of "the bends," contributing to the fields of hyperbaric medicine and occupational health.

This harrowing chapter in the bridge's construction is a testament to the immense human sacrifice required to achieve the impossible. It stands as a powerful reminder of the courage and resilience of the workers who gave their health, and in some cases their lives, to connect two great cities.

The video above provides a deeper look into the perilous conditions inside the caissons and the science behind the disease that haunted the bridge's builders, highlighting how their sacrifice became an unwilling but vital contribution to scientific progress.
