On their return from their European studies, Washington's father died in 1869 of
tetanus, following an accident at the bridge site. Washington Roebling was assigned as chief engineer of the Brooklyn Bridge's construction. As he immersed himself in the project, Washington developed
decompression sickness, which was known at the time as "caisson disease", by going to underwater depths to study the placement of caissons and not rising at the proper speed. It affected him so severely that he became bed-ridden. As the only person to visit her husband during his sickness, Emily Roebling relayed information from Washington to his assistants and reported to him the progress of work on the bridge. She developed an extensive knowledge of
strength of materials,
stress analysis,
cable construction, and calculating
catenary curves through Washington's teachings. She complemented her knowledge by her prior interest in and study of the bridge's construction when her husband had been appointed as chief engineer. For the decade after Washington was confined to his sick bed, Roebling was dedicated to the completion of the Brooklyn Bridge. She took over much of the chief engineer duties, including day-to-day supervision and project management. Emily and her husband jointly planned the bridge's continued construction. She dealt with politicians, competing engineers, and all those associated with work on the bridge, to the point where people believed she was behind the bridge's design. In 1882, Washington's title of chief engineer was in jeopardy because of his extended illness. To allow him to retain his position, Roebling lobbied for him in meetings with engineers and politicians to defend her husband's work. To the Roeblings' relief, the politicians responded well and permitted Washington to remain chief engineer of the Brooklyn Bridge. The Brooklyn Bridge was completed in 1883. In advance of the official opening, carrying a rooster as a sign of victory, Emily Roebling was the first to cross the bridge by carriage. At the opening ceremony, Roebling was honored in a speech by
Abram Stevens Hewitt, who said that the bridge was ==Later life==
