Squire Whipple

Died 15 Mar 1888 at age 83 (born 16 Sep 1804).U.S. civil engineer, inventor, and theoretician who provided the first scientifically based rules for bridge construction, was considered one of the top engineers of the 19th Century, and was known as the "father of iron bridges." He began his career as a bridge-builder in 1840 by designing and patenting an iron-bridge truss. During the next ten years he built several bridges on the Erie canal and the New York and Erie railroad. His design of the Whipple truss bridge was the model for hundreds of bridges that crossed the Erie Canal in the late 19-th century. Before developing his design, Whipple worked for several years on surveys, estimates, and reports for the enlargement of the Erie Canal, and in 1840 he patented a scale for weighing canal boats. He later built the first weighing lock scale constructed on the Erie Canal. The invention of the steam engine required bridges which could support heavy live loads and this motivated Squire to turn his attention to bridges. In 1853, he completed a 146-ft span iron railroad bridge near West Troy (now Watervliet), N.Y. His book on the design of bridges using scientific methods (1847) was the first of its kind. The formulas and his methods are still useful. He obtained a patent for his lift draw-bridge in 1872.[Image: Bowstring Truss designed by Squire Whipple. This rare cast-and wrought iron bridge, built in 1872, was located in Coshocton County, Ohio, crossing Wills Creek on Linton Township Road 144.]
