Newark Airport
Society: ASCE Main Category: Aerospace & Aviation Sub Category: Aviation Era: 1920-1929 DateCreated: 1928 Liberty International Airport (EWR) Newark State: NJ Zip: 07114 Country: USA Website: Creator: Many

In May 1927, the same month of Charles A. Lindbergh's famous transatlantic flight from New York to Paris, a fact-finding commission appointed by the U.S. Secretary of Commerce concluded that Newark would be the ideal location for an airfield to serve the greater New York/New Jersey metropolitan area.

Civic leaders wasted no time; construction began on the Newark Airport in January 1928. Nine months and $1,750,000 later, 68 acres of soggy marshland had been filled and converted to an airport.

Morris Canal Reaction Turbine
Society: ASME Main Category: Mechanical Sub Category: Water Era: 1850-1859 DateCreated: 1850 Morris Canal Greenwich Township State: NJ Zip: 07840 Country: USA Website: Creator: Renwick, James

This reaction or "Scotch" turbine had as its antecedent the steam reaction wheel invented in Greek Alexandra by Hero around 100 B.C.. It found widespread hydraulic application in the United States from the beginning of the nineteenth century to mid-century when French-inspired hydraulic turbine design pushed reaction wheels into obsolence.

As ideas developed, they abandoned infrared radiation to instead concentrate upon visible light. The concept originally was called an "optical maser". In 1958, Bell Labs filed a patent application for their proposed optical maser; and Schawlow and Townes submitted a manuscript of their theoretical calculations to the Physical Review, published that year in Volume 112, Issue No. 6. Simultaneously, at Columbia University, graduate student Gordon Gould was working on a doctoral thesis about the energy levels of excited thallium.

Cranetown Triangulation Site
Society: ASCE Main Category: Civil Sub Category: Boundaries & Surveys Era: 1800-1829 DateCreated: 1817 Kip's Castle Park Essex County State: NJ Zip: Country: USA Website: Creator: Hassler, Ferdinand

The precise system of measurements provided today by the U.S. Coast and Geodetic Survey originated with an act of Congress under the administration of Thomas Jefferson in 1807 that funded work on "an accurate chart" of America's coastal waters. Intended to aid sea-going commerce, the first work on this project, carried out in 1816 and 1817, helped establish a complex grid of geodetic reference points on which much of our land- and sea-based navigation now depends.

Edison with his early phonograph
Society: ASME Main Category: Mechanical Sub Category: Communications and Data Processing Era: 1870-1879 DateCreated: 1877 37 Honeysuckle Avenue West Orange State: NJ Zip: 07052 Country: USA Website: Creator: Edison, Thomas

Edison's simple and unprecedented instrument allowed for the first time the permanent recording and reproduction of sound, especially the human voice. On December 6, 1877, Edison put tinfoil around the cylinder, turned the handle of the shaft and, shouting into one of the diaphragms, recorded a verse of Mary Had a Little Lamb "almost perfectly." From this machine evolved the phonographs and record industries of the world.

Atlantic City Convention Hall
Society: ASCE Main Category: Civil Sub Category: Buildings Era: 1920-1929 DateCreated: 1926-1929 2301 Boardwalk Atlantic City State: NJ Zip: 08401 Country: USA Website: Creator: Lockwood-Greene & Co.

The quantities of materials used in the building are staggering: 12,000 tons of structural steel; 42,000 cubic yards of concrete - consisting of 65,000 barrels of cement and 25,000 tons of sand; 360,000 feet of piling; and 10,000,000 bricks. At the time of its construction, Atlantic City Municipal Convention Hall was believed to be the world's largest hall, capable of seating 40,000 people. It continues to serve as a meeting place for shows, pageants, sporting events, and conventions. It is a structure of heroic proportions.

George Washington Bridge
Society: ASCE Main Category: Civil Sub Category: Bridges Era: 1930-1939 DateCreated: 1931 George Washington Bridge Fort Lee State: NJ Zip: 07024 Country: USA Website: Creator: Ammann, Othmar

"An essential part of the human experience is to create an aesthetic atmosphere."

The George Washington Bridge represented a departure in suspension bridge design. Chief Engineer O.H. Ammann developed a system of stiffening trusses that offered greater flexibility and saved the project nearly $10 million. Initially, just six of the upper eight lanes were paved, but Ammann designed the bridge to easily accommodate a future lower level.

Swiss-born O.H. Ammann (1879-1965) was Chief Engineer for the Port Authority of New York and New Jersey during the bridge's construction.

This collection of equipment—all of it maintained in operating condition and used for educational purposes—was established in 1987. It spans the period from the late 19th century to the 1940s, when steam was the prime motive force for most U.S. industries, including rail and marine transportation. The collection of about 25 items (mostly stationary steam) includes a locomotive, switcher, and steam tractor: Locomotive #385 Consolidation 2-8-0 designed for fast freight service was built by Baldwin Locomotive Works of Philadelphia in November 1907 for the Southern Railway.

Holland Tunnel
Society: ASCE Main Category: Civil Sub Category: Tunnels Era: 1920-1929 DateCreated: 1927 Hudson River Jersey City State: NJ Zip: 07310 Country: USA Website: Creator: Holland, Clifford

The 1.6-mile Holland Tunnel was the first underwater vehicular crossing of the Hudson River and the first tunnel specifically designed for automobiles and trucks. It dramatically reduced the time required to traverse the Hudson River, a trip previously possible only by ferry. 

A major difficulty when tunneling beneath a river is to keep water and mud from inundating the workers and equipment in the tunnel. Builders of the Holland Tunnel used a shield that enveloped the work site as the excavation progressed; this also avoided obstruction of shipping traffic during construction.

Great Falls Raceway and Power System

Visionary Alexander Hamilton, the United States' first Secretary of the Treasury, visited the Great Falls of the Passaic River with George Washington in 1778. The 77-foot-high, 280-foot-wide waterfall inspired his dream of abundant, inexpensive energy as the means for economic independence from foreign markets.
