See also:JOHN See also:AUGUSTUS See also:ROEBLING (1806-1869)
, See also:American See also:civil engineer, was See also:born at See also:Muhlhausen, See also:Prussia, on the 6th of See also:June 18o6
.
Soon after his See also:graduation from the See also:polytechnic school at See also:Berlin he removed to the See also:United States; and in 1831 entered on the practice of his profession in western See also:Pennsylvania
.
He established at See also:Pittsburg a manufactory of See also:wire-rope, and in May 1845 completed his first important structure, a suspended See also:aqueduct across the See also:Allegheny See also:river
.
This was followed by the See also:Monongahela suspension See also:bridge at Pittsburg and several suspended aqueducts on the See also:Delaware & See also:Hudson See also:Canal
.
Removing his wire manufactory to Trenton, New See also:Jersey, he began, in 1851, the erection at See also:Niagara Falls of a See also:long span wire suspension bridge with See also:double roadway, for railway and See also:carriage use (see BRIDGE), which was completed in 1855
.
Owing to the novelty of its See also:design, the most eminent See also:engineers regarded this bridge as foredoomed to failure; but, with its See also:complete success, demonstrated by long use, the number of suspension See also:bridges rapidly multiplied, the use of wire-See also:ropes instead of See also:chain-cables becoming all but universal
.
The completion, in 1867, of the still more remarkable suspension bridge over the See also:Ohio river at See also:Cincinnati, with a clear span of 1057 ft., added to See also:Roebling's reputation, and his design for the See also:great bridge spanning the See also:East river between New See also:York and See also:Brooklyn was accepted
.
While personally engaged in laying out the towers for the bridge, Roebling received an accidental injury, which resulted in his See also:death, at Brooklyn, from See also:tetanus, on the 22nd of See also:July 1869
.
The bridge was completed under the direction of his son, See also:Washington See also:Augustus Roebling (b
.
1837), who introduced several modifications in the See also:original plans
