John A. Roebling
John Augustus Roebling (born Johann August Röbling; June 12, 1806 – July 22, 1869) was a German-born American civil engineer.〔 He designed and built wire rope suspension bridges , in particular the Brooklyn Bridge, which has been designated as a National Historic Landmark and a National Historic Civil Engineering Landmark.
==Education==
At first John attended the gymnasium in Mühlhausen. Recognizing his intelligence at a young age, Roebling's mother, Friederike Dorothea Roebling arranged for him to be tutored in mathematics and science at Erfurt by Ephraim Salomon Unger. He went to Erfurt when he was 15. In 1824 he passed his Surveyor's examination and returned home for a year. In 1824 he enrolled for two semesters at the Bauakademie in Berlin where he studied architecture and engineering under Martin Friedrich Rabe (1765–1856), bridge construction and foundation construction under Johann Friedrich Dietlein (1782–1837), hydraulics under Johann Albert Eytelwein (1764–1848), and languages. Roebling also attended lectures of the philosopher Hegel. Roebling developed an interest in natural philosophy and many years later he worked on a 1000-page treatise about his own concepts of the universe.〔Roebling, Washington A., ''Washington Roebling's Father'', 2008, ASCE Press, Reston VA〕
In 1825 Roebling got a government job at Arnsberg, Westphalia, working on military road building for four years. During this period he made sketches for suspension bridges. In 1829 he returned to his home to work out his final thesis and prepare for his second engineer examination. For unknown reasons, he never took the examination.〔Güntherroth, Nele, ''Roebling's Development to being an Engineer'', 2006, Proceedings John A Roebling Symposium, ASCE, Reston VA〕
