Building this bridge was a saga of immense personal loss and incredible resilience. It began with the designer, John Roebling, who died of tetanus after his foot was crushed in a ferry accident before construction even truly started. Leadership then passed to his son, Washington Roebling. To secure the bridge’s foundations, workers had to descend into massive underwater chambers called caissons. The high-pressure environment caused what we now call decompression sickness, or the bends, which paralyzed Washington and left him bedridden for a decade. From his bedroom in Brooklyn Heights, Washington watched the construction through a telescope while his wife, Emily Warren Roebling, became his voice. Emily taught herself higher mathematics and civil engineering to relay complex instructions to the site. She became the first woman to cross the bridge when it was finished, carrying a live rooster as a symbol of victory. Without Emily’s leadership, the bridge we are standing on might never have been completed.
