John Augustus Roebling

John Augustus Roebling , 1806-69, German-American engineer, b. Mulhouse. He studied engineering in Berlin and in 1831 came to the United States. He demonstrated the practicability of steel cable and established a plant for manufacturing it at Trenton, N.J. A pioneer in the building of suspension bridges, he built the Allegheny Suspension Bridge (completed 1845) at Pittsburgh, the Niagara Falls Suspension Bridge (completed 1855), and the Cincinnati and Covington Bridge over the Ohio (completed 1867). His most ambitious project was the Brooklyn Bridge. It was scarcely begun when Roebling, directing operations, was injured in an accident and died a few days later.

His son Washington Augustus Roebling, 1837-1926, b. Saxonburg, Pa., grad. Rensselaer Polytechnic Institute, 1857, had aided his father in building the Allegheny Suspension Bridge. During the Civil War he joined the Union army as a private, was transferred to Irvin McDowell's engineering staff, and rose to the rank of colonel. He went to Europe to study engineering and especially pneumatic caissons. After his father's death he directed the construction of the Brooklyn Bridge. Because of continuous underground work he was stricken (1872) with decompression sickness (caisson disease), but despite his invalidism he directed the project until the bridge was opened to traffic (1883). In 1888 he took over the management of the Roebling plant in Trenton.

Roebling, John Augustus (1806–69) US engineer and industrialist, b. Germany. In 1831 he emigrated to the USA and became a civil engineer. He directed the construction of suspension bridges across the Allegheny and Niagara rivers. He was appointed chief engineer of the Brooklyn Bridge in 1869, but was killed in an accident during an early survey. His son Washington Augustus Roebling (1837–1926) was also an engineer and industrialist. During the Civil War, he served as a military engineer and balloonist. In 1869 he succeeded his father as chief engineer on the Brooklyn Bridge until its completion in 1883.
