Biographical/Historical note:
Wendel Bollman (1814-1884) was a self-educated engineer who began working for the Baltimore and Ohio Railroad as a carpenter and devised a bridge-trussing system that was a series of independently supported floor beams, each carried by a double pair of eye-bar ties. He patented the system in 1852 and it became known as the "Bollman Truss". The Bollman truss was used on the Baltimore and Ohio Railroad, its subsidiaries, and several roads. It was the first bridge trussing system which all princicpal elements were made of iron. Bollman trusses were built until about 1875 nd rtained in service until about 1890.
