John Augustus Roebling (born Johann August Röbling, June 12, 1806 in Mühlhausen - July 22, 1869) was a German-born civil engineer famous for his wire rope suspension bridge designs, in particular, the design of the Brooklyn Bridge.
In 1841, at Saxonburg, he began producing wire rope.
During this time, canal boats from Philadelphia often were transported over the Allegheny Mountains on railroad cars to access waterways on the other side of the mountains, so that the boats could continue to Pittsburgh.
The system of inclines and levels that moved the boats and conventional railroad cars was a state-owned enterprise, the Allegheny Portage Railroad. The railroad cars were moved up and down the inclines by a long loop of hemp rope up to nine inches in circumference. The hemp ropes were very expensive, but rendered poor service life.
Roebling remembered an article he read about wire ropes. Soon after, he started developing a 7-strand wire rope at a ropewalk he created on the meadow of his farm.
In 1867 Roebling started design work on what is now called the Brooklyn Bridge, spanning the East River in New York. One day in 1869 he was standing at the edge of a dock, working on fixing the location where the bridge would be built, when his foot was crushed by an arriving ferry. His injured toes were amputated. He refused further medical treatment and wanted to cure his foot by "water therapy" (continuous pouring of water over the wound). His condition deteriorated. He succumed to tetanus 24 days after the accident.
