| Civil engineer, born in Hardwick, Massachusetts, USA. He worked on canals and railroads until 1841 and devised several new apparatuses. In 1840 he devised an apparatus for weighing canal boats and a weighing lock scale, and in 1841 he patented the bowstring iron truss bridge and the Whipple trapezoidal bridge. Beyond his actual structures, he made his major contribution with A Work on Bridge Building (1847), a pioneer work of scientific engineering with its method for computing stress. |
