Squire Whipple

Squire Whipple (September 16, 1804 – March 15, 1888) was a civil engineer born in Hardwick, Massachusetts, USA. His family moved to New York when he was thirteen. He received his secondary education at the Fairfield Academy in Herkimer, New York, and graduated from Union College in New York after only one year. He has become known as the father of iron bridge building in America.[1]

Bridges
Whipple bowstring arch truss bridge, built in 1867-'69, over Normans Kill in Albany, New York

Constructed by S. DeGraff of Syracuse, New York, 1867–69, the Whipple Cast and Wrought Iron Bowstring Truss Bridge over Norman's Kill in Albany, New York, is a very well preserved example of a Whipple Bowstring Arch Truss, still in daily use, with no posted weight limits. Due to the sleek appearance, many users think it is a modern bridge. (The Delaware Turnpike once ran through both neighborhoods until 1929 with the construction of a new much higher, longer, and wider Delaware Avenue Bridge over the Normans Kill. This allowed commuters to and from Albany to bypass both Normansvilles. The original Whipple Bowstring bridge still stands, though it has been closed to vehicular traffic since January 1990.) His patented designs were implemented in numerous bridges, both Whipple truss and prefabricated bowstring arch truss bridges, which became the standard design for Erie Canal crossings; using an economical mix of wrought iron for tension members and cast iron in compression. Another such arch is the Shaw Bridge, the only known Whipple bowstring at its original location and the only known "double" believed extant, the only "a structure of outstanding importance to the history of American engineering and transportation technology."[2] There are at least four other Whipple bowstrings standing in Central New York state, and one in Newark, Ohio.

Patents
Constructed after Whipple's death, the Cairo Rail Bridge in two 518 feet (157.9 m) Whipple truss spans were the largest of that design ever constructed.[3]
