From mid-1865 to 1867, Roebling worked with his father on the Cincinnati-Covington Bridge (now the
John A. Roebling Suspension Bridge). While traveling in Europe to research wire mills, bridges and caisson foundations, his only son,
John A. Roebling II, was born. After returning to the U.S. in 1868, Washington became assistant engineer on the Brooklyn Bridge and was named chief engineer after his father's death in mid-1869. He made several important improvements on the bridge design and further developed bridge building techniques. Thus, he designed the two large pneumatic
caissons that became the foundations for the two towers. In 1870, fire broke out in one of the caissons; from within the caisson, Roebling directed the efforts to extinguish the flames. Besides the bends, he may have had additional afflictions, possible
neurasthenia, side effects of treatments, and secondary drug addiction. His wife,
Emily Warren Roebling, who had taught herself bridge construction, took over much of the chief engineer's duties including day-to-day supervision and project management. Although the couple jointly planned the bridge's continued construction, Emily successfully lobbied for formal retention of Washington as chief engineer. McCullough remarked that "nowhere in the history of great undertakings is there anything comparable" to Roebling conducting the largest and most difficult engineering project ever "in absentia." Roebling would battle the after-effects from the caisson disease and its treatment the rest of his life. – Portrait of Washington A. Roebling –
