The Old Cape Henry Light house was the first construction project authorized by the First Congress. Constructed by John McComb, Jr. of New York City, this project set the stage for all subsequent public works projects of the Federal Government. In addition, this specific lighthouse was a vital navigation aid to all shipping through the Virginia Capes, thereby enhancing international and coastal trade with the Mid-Atlantic States.

Founded by Eleuthère Irénéé du Pont (1771-1834), the Brandywine River Mills became the largest maker of explosive black powder in the United States. That success resulted directly from the firm's pioneering use of gunpowder processing machinery driven by water wheels and water turbines.

The Apollo lunar module (LM-13) was developed by the Grumman Aircraft Engineering Corp. (now Northrop Grumman). The LM's main functions were to carry two astronauts from lunar orbit to the moon's surface, and then return them to lunar orbit to rendezvous and dock with the Apollo command-service modules. On the surface, the LM served as a shelter and base of operations as the astronauts carried out their exploration and experiments. On July 20, 1969, the LM "Eagle" touched down on the moon, becoming the first piloted spacecraft to land on a celestial body other than Earth.

Ditch Witch DWP Service-Line Trencher
Society: ASME Main Category: Mechanical Sub Category: Materials Handling & Excavation Era: 1950-1959 DateCreated: 1952 Ditch Witch Museum & Heritage Center Perry State: OK Zip: 73077 Country: USA Website: Creator: Malzahn, Ed, Malzahn, Charlie

The DWP was the first mechanized, compact service-line trencher developed for laying underground water lines between the street-main and the house. This machine, first produced in 1949, replaced manual digging, thus making installation of running water and indoor plumbing affordable for the common household. The DWP paved the way for the creation of a worldwide trenching-products industry, its machines used for the installation of all underground utilities including telephone, cable-TV and data, and fiber-optic cables.
