Report Of John A Roebling To The Presidents And Directors Of The Niagara Falls Suspension And Niagara Falls International Bridge Companies

John Roebling was one of the nineteenth century's most brilliant engineers, ingenious inventors, successful manufacturers, and fascinating personalities. Raised in a German backwater amid the war-torn chaos of the Napoleonic Wars, he immigrated to the US in 1831, where he became wealthy and acclaimed, eventually receiving a carte-blanche contract to build one of the nineteenth century's most stupendous and daring works of engineering: a gigantic suspension bridge to span the East River between New York and Brooklyn. In between, he thought, wrote, and worked tirelessly. He dug canals and surveyed railroads; he planned communities and founded new industries. Horace Greeley called him "a model immigrant"; generations later, F. Scott Fitzgerald worked on a script for the movie version of his life. Like his finest creations, Roebling was held together by the delicate balance of countervailing forces. On the surface, his life was exemplary and his accomplishments legion. As an immigrant and employer, he was respected throughout the world. As an engineer, his works profoundly altered the physical landscape of America. He was a voracious reader, a fervent abolitionist, and an engaged social commentator. His understanding of the natural world, however, bordered on the occult and his opinions about medicine are best described as medieval. For a man of science and great self-certainty, he was also remarkably quick to seize on a whole host of fads and foolish trends. Yet Roebling held these strands together. Throughout his life, he believed in the moral application of science and technology, that bridges--along with other great works of connection, the Atlantic Cable, the Transcontinental Railroad--could help bring people together, erase divisions, and heal wounds. Like Walt Whitman, Roebling was deeply committed to the creation of a more perfect union, forged from the raw materials of the continent. John Roebling was a complex, deeply divided yet undoubtedly influential figure, and this biography illuminates not only his works but also the world of nineteenth-century America. Roebling's engineering feats are well known, but the man himself is not; for alongside the drama of large scale construction lies an equally rich drama of intellectual and social development and crisis, one that mirrored and reflected the great forces, trials, and failures of nineteenth century America.

Named a Gift Book for the Discerning New Yorker by The New York Times In the Shadow of Genius is the newest book by photographer and author Barbara Mensch. The author combines her striking photographs with a powerful first-person narrative. She takes the reader on a unique journey by recalling her experiences living alongside the bridge for more than 30 years, and then by tracing her own curious path to understand the brilliant minds and remarkable lives of those who built it: John, Washington, and Emily Roebling. Many of Mensch’s photographs were inspired by her visits to the Roebling archives housed at Rutgers University, where she pieced together through notebooks, diaries, letters, and drawings the seminal locations and events that affected their lives. Following in their footsteps, Mensch traveled to Mühlhausen, Germany, the birthplace of John Roebling; to Saxonburg, Pennsylvania, where Roebling established a utopian community in 1831; to Roebling aqueducts and bridges in Pennsylvania, Ohio, and New York; and to the Civil War battlefield in Gettysburg, Pennsylvania, where Washington Roebling, the son of the famous engineer, valiantly served as a Union soldier. The book begins and ends with Mensch’s unique photographs of the Brooklyn Bridge, including never-before-seen images captured deep within the structure. The book creatively fuses contemporary photography with the historical record, giving the reader a new perspective on contemplating the masterwork. Fernanda Perrone, Curator of Special Collections and the Roebling Family Archive at Rutgers University, has contributed a Foreword.

Excerpt from Final Report of John A. Roebling, Civil Engineer, to the Presidents and Directors of the Niagara Falls Suspension and Niagara Falls International Bridge Companies: May 1, 1855 The aggregate section of the upper links of the four chains is 372 square inches, and their ultimate strength at 32 tons, equal to I tons. The strain upon the lowest link is at least diminished one-third, which leaves 7936 tons. This pressure on the New York Side is resisted by a sheet of solid rock of no less ex tent than 100 ft. Long, 70 ft. Wide, and 20 ft. Deep. Thisrock weighs about 160 lbs. Per cubic foot. Now assuming only 200 lbs. Of resistance in the solid rock, we have a mass Of cubic 'feet, opposing a force of tons, without taking into account the weight of the superincumbent masonry and embank ment. Admitting that the rock was full of, fissures and seams, which is not the case, the entire safety of the anchorage is evident.
