What Has Changed in the Last Century
Collier's wrote of Washington Roebling in 1921 as a living man, president of the Trenton wire works; he died at Trenton on July 21, 1926, aged 89, having been left an invalid by caisson disease contracted in the Brooklyn Bridge's underwater foundations. The article's silence on his wife is the biggest gap modern accounts fill: Emily Warren Roebling carried his instructions to the site for years and is now routinely credited as a working force behind the bridge's completion in 1883. Of the elder Roebling's structures, the 1855 Niagara railway suspension bridge was replaced by a steel arch in 1897 and the Pittsburgh bridges are long gone, but the Brooklyn Bridge still carries traffic, and the Cincinnati span, finished in 1867, was renamed the John A. Roebling Suspension Bridge in 1983. The family firm supplied the cables for the Golden Gate Bridge in the 1930s before passing out of Roebling hands in the 1950s.
