Leffert L. Buck (
1837-
1909) was an American civil engineer and a pioneer in the use of steel arch bridge structures. His projects included the steel suspension bridge over the
Niagara Gorge[?] and two of
New York City's most notable landmarks: the
Brooklyn Bridge (with John Augustus Roebling and Washington Roebling) and the
Williamsburg Bridge[?] (with
Henry Hornbostel[?]). The latter, at 1,600 feet, was the longest bridge in the world at the time and a key factor in opening
Brooklyn up as a working class neighborhood for
Manhattan.
