1. Squire Whipple
Squire Whipple; Born 16 Sep 1804; died 15 Mar 1888.
Whipple was a U.S. civil engineer, inventor, and theoretician who provided the first scientifically based rules for bridge construction. 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.
