Leffert L. Buck (1837–1909) was an American civil engineer and a pioneer in the use of steel arch bridge structures. Leffert graduated from Rensselaer Polytechnic Institute in Troy, New York, in 1868. Some of his projects include: *The Verrugas Viaduct on the Oroya Railroad in Peru (in the early 1870s) *The Whirlpool Rapids Bridge over the Niagara Gorge *The Williamsburg Bridge, one of New York City's most notable landmarks, with Henry Hornbostel. At 1,600 feet it was the longest bridge in the world when completed in 1903 and a key factor in opening Brooklyn up as a working-class neighborhood for Manhattan. The bridge is well known for its vast reach and massive symmetry. *The Pont De Rennes bridge (former Platt Street bridge) that spans the Genesee River in Rochester at the High Falls. *Engineered the Queensboro Bridge in New York City. Before earning his civil engineering degree from RPI, Buck fought for the Union Army in the American Civil War under General Slocum, participating in the battles at Antietam, Chancellorsville, Gettysburg, Lookout Mountain, Missionary Ridge, Peachtree Creek, Resaca and Ringgold Gap. A dormitory in the Quadrangle complex at Rensselaer is named after him.〔(【引用サイトリンク】url=http://www.lib.rpi.edu/dept/library/html/Archives/buildings/quadrangle.html )〕 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Leffert L.
