Roebling, John Augustus

Roebling, John Augustus
born , June 12, 1806, Mühlhausen, Prussia
died July 22, 1869, Brooklyn Heights, N.Y., U.S.

German-U.S. civil engineer, a pioneer in the design of suspension bridges.

He immigrated to the U.S. in 1831. His best-known work is New York's Brooklyn Bridge. In the 1850s and '60s Roebling and his son Washington (1837–1926) built four suspension bridges: two at Pittsburgh, one at Niagara Falls (1855), and one at Cincinnati (1866). When his design for a bridge connecting Brooklyn and Manhattan was accepted, he was appointed chief engineer. He died from an injury he received as construction began. Washington completed the project in 1883; himself incapacitated from 1872 by decompression sickness, his completion of the work depended heavily on his wife, Emily Warren Roebling.

born , June 12, 1806, Mühlhausen, Prussia
died July 22, 1869, Brooklyn Heights, N.Y., U.S.
 German-born U.S. civil engineer (civil engineering), a pioneer in the design of steel suspension bridges (suspension bridge). His best known work is the Brooklyn Bridge, New York City, completed under the direction of his eldest son, Washington Augustus, in 1883.

      After graduating from the polytechnic school in Berlin, Roebling worked for the Prussian government for three years and at the age of 25 emigrated to the U.S. He settled with others from his hometown in a small colony that was later called Saxonburg, near Pittsburgh, in the hills of western Pennsylvania. He married the daughter of another Mühlhausen emigrant, and they had nine children. After a few years of unsuccessful farming, John Roebling went to the state capital in Harrisburg and applied for employment as a civil engineer.

      He had often watched canalboats being hauled over hills from one watershed to another, and he persuaded the canal commissioners to let him replace the hempen hawsers with wire cables. He developed his own method for stranding and weaving wire cables, which proved to be as strong and durable as he had predicted. The demand for such cable soon became so great that he established a factory to manufacture it in Trenton, N.J. This was the beginning of an industrial complex that finally was capable of producing everything from chicken wire to enormous 36-inch (91-centimetre) cables. It remained a family-owned business, carried on by three generations of Roeblings.

 Roebling was less a businessman than an engineer, and with the growth of his reputation as a designer and builder of long-span suspension bridges, he spent less and less time at the Trenton factory. His eldest son, Washington, joined him in his work, and in the 1850s and 1860s they built four suspension bridges: two at Pittsburgh, one at Niagara Falls, and another across the Ohio River between Cincinnati, Ohio, and Covington, Ky., with a main span of 1,051 feet (320 metres). New York state accepted Roebling's design for a bridge connecting Brooklyn and Manhattan with a span of 1,595 ft (486 m) and appointed him chief engineer.

      Work on the bridge cost Roebling his life. He was taking final compass readings while standing on some pilings at a ferry slip and did not notice that a boat was docking. As it banged into the slip, one of his feet was caught between the pilings. He was rushed to his son's house in Brooklyn Heights, where the doctors amputated his injured toes. Three weeks later, he died of tetanus at the age of 63. His son carried on his work on the Brooklyn Bridge.
