Washington Roebling

From Wikipedia, the free encyclopedia

Washington Augustus Roebling (May 26, 1837July 21, 1926) was an American civil engineer best known for his work on the Brooklyn Bridge, which was initially designed by his father John A. Roebling.

The eldest son of John Roebling, Washington was born in the Pittsburgh area town of Saxonburg, Pennsylvania, a town co-founded by his father and his uncle, Karl Roebling. Growing up in a strict Prussian home, his early schooling consisted of tutoring by Riedel and under Henne in Pittsburgh. He eventually attended the Trenton Academy and acquired further education at the Rensselaer Polytechnic Institute in Troy, New York, from 1854-57. Following his graduation as civil engineer (C.E.), he joined his father to work as a bridge builder. From 1858 to 1860, he assisted his father on the Allegheny Bridge project, living in a boarding house on Penn Street. Following the completion of the bridge, he returned to Trenton to work in his father's wire mill.

On April 16, 1861, Roebling enlisted as a private in the New Jersey Militia. Seeking more than garrison duty, he resigned after two months and re-enlisted with the New York Artillery, United States Army. During the American Civil War, Roebling saw action repeatedly, most notably at the Battle of Gettysburg. Days before the battle started, he noted the movement of Robert E. Lee's Confederate Army toward the North while conducting air balloon reconnaissance. On July 2, 1863, Roebling was one of the initial soldiers on Little Round Top. He was approached by Brig. Gen. Gouverneur K. Warren and ordered to "go find a regiment, any regiment, the first one you come to and tell them to get up here immediately." The first regiment he came upon was commanded by Col. Strong Vincent of the V Corps, whose brigade immediately occupied the hill and defended the left flank of the Army of the Potomac against repeated Confederate attacks. Later, Roebling helped hoist artillery up the hill with several others, in order to protect and secure its important tactical position.

Roebling was brevetted lieutenant colonel in December 1864 for gallant service, ending his service brevetted colonel. After the war, he worked with his father on the Cincinnati-Covington Bridge (now the John A. Roebling Suspension Bridge) from 1865-67 and took over supervision of the Brooklyn Bridge after his father's death in 1869. The Brooklyn Bridge was erected out of economic necessity and urban sprawl (Brooke and Davidson 2006). New York City was a huge immigration hub. He made many important improvements on the bridge design and development of major bridge building techniques, such as the use of caisson foundations. Excavation methods for the caisson construction consisted of shovel, pick, wheelbarrow, steel bar stone breakers, winches and ten ton hydraulic jacks, eventually blasting after Washington Roebling conducted a series of experiments in the caisson. Initial rate of caisson excavation and lowering produced 6 inches per week, with a workforce of 360 people constructing the bridge (Trachtenberg 1965).

Decompression sickness due to working in compressed air under the river, combined with over work, shattered his health and rendered him unable to visit the site, but he continued to oversee the Brooklyn project to successful completion in 1883. His wife, Emily Warren Roebling, took over the day-to-day supervision and visits to the site and successfully lobbied for retention of him as chief engineer. Roebling would battle the after-effects from the disease and various treatments the rest of his life.

Following the Brooklyn project, Roebling and his wife lived in Troy, New York, from 1884-88, as their only child, John A. Roebling, II, also attended the Rensselaer Polytechnic Institute (RPI). When their son graduated, the Roeblings returned to Trenton, moving to 191 West State Street in 1892. His wife Emily died in 1903 from stomach cancer. Roebling was remarried in 1908 to Cornelia Witsell Farrow of Charleston, South Carolina.

Following the sudden death of his nephew, Karl Gustavus Roebling, in 1921, Roebling became president of John A. Roebling's Sons Company. He died in 1926, after being bedridden for two months, at age 89.

Roebling's most passionate hobby was collecting rocks and minerals. His collection of over 16,000 specimens was donated to the Smithsonian Institution and became an important part of its mineral and gem collection.

A plethora of his manuscripts, photographs, and publications, can be found in the Roebling collections at Rutgers University in New Brunswick, New Jersey, and at Rensselaer Polytechnic Institute in Troy, New York.
