Inferior water and the lack of a sufficient water supply prompted public pressure to find a significant water source for the 360,000 of people living in New York City at the time. Studies determined that the Croton River, 40 miles north of the city, was the best available source. The original system served as a prototype for large-scale water supply projects across America.


In 1899, engineers from the City of Chicago's Division of Bridges and Viaducts performed a survey of moveable bridge design in the U.S. and Europe. Their study led to the conclusion that the unusual trunnion bascule design would best meet their needs.


The Cornish-Windsor Covered Bridge is the longest wooden bridge in the United States and the longest two-span, covered bridge in the world. It is also a classic example of wooden bridge-building in 19th-century America. With copious supplies of timber at hand and a generous reserve of carpentry skills available, bridge builders in early America quickly discarded the masonry arches prevalent in the Old World. Instead, they opted for a revival of timber-truss designs dating from 14th century Europe.


The Cooperative Fuel Research (CFR) engine is used extensively throughout the world for testing, research, and instruction in the performance of fuels and lubricants for the internal combustion engine. Principal design work on this prototype engine was accomplished by engineers of Waukesha Motor Company, now a division of Dresser Industries, who served on a Cooperative Fuel Research Committee with representatives of the American Petroleum Institute, Society of Automotive Engineers, Automobile Manufacturers Association, and the National Bureau of Standards.

These engines, built by Cooper & Co., of Mount Vernon are among the oldest surviving agricultural steam engines to show the evolution from the portable, skid-mounted engine (ca. 1860) to the horse-drawn engine (1875), through the self-propelled but horse-guided engine (1875) and finally to the self-propelled, self-steered traction engine (1883). Such engines powered the conversion to mechanized farming, which was a great hallmark of the Industrial Revolution.

This compressor was a product of the combined technology and design heritage of both the C. & G. Cooper Company of Mount Vernon and the Bessemer Gas Engine Company of Pennsylvania, which had merged in 1929. Ralph L. Boyer, the chief architect of the GMV, worked for Cooper-Bessemer from 1926 through 1965.
