The Kamehameha V Post Office is the oldest surviving public building in the U.S.  constructed with reinforced concrete. The success of this early structure helped establish the value of reinforced concrete as a durable construction material.

Brickmaker J.G. Osborne was chosen to provide design and construction. He  immigrated to Hawaii from Yorkshire, England, and was aware of the recent  development of Portland cement and its expanding use in Europe. It is believed that the leaders of Hawaii were anxious to adopt British skills, which influenced their selection of Osborne.

This ironworks exemplified the adaptability required for industrial survival in a dynamic technical environment. It was a major western producer of mechanical equipment used in mining (especially large hydraulic machines), ship propulsion, irrigation, power generation, optical telescope mounts, and nuclear research.

When Joseph Priestley discovered oxygen in 1774, he answered age-old questions of why and how things burn. An Englishman by birth, Priestley was deeply involved in politics and religion, as well as science. When his vocal support for the American and French revolutions made remaining in his homeland dangerous, Priestley left England in 1794 and continued his work in America until his death. His library of some 1,600 volumes and his chemical laboratory, where he first isolated carbon monoxide, were probably the best in the country at that time.

This is one of several, similar inclines built in western Pennsylvania during the late 19th century. It was designed by Samuel Diescher (1839-1915) after the great flood of 1889, to provide an efficient means of transportation between Westmont and the Conemaugh Valley. (See also the Monogahela and Duquesne Inclines in Pittsburgh.)

In 1866, the Covington and Cincinnati Suspension Bridge was the largest suspension bridge in the world. Also called the Ohio Bridge, it was officially renamed the John A. Roebling Bridge in 1983. It was the first permanent bridge over the Ohio River and the only public project in America financed by private investors during the Civil War.

Renowned bridge designer John A. Roebling proposed the structure in 1846; but building the bridge would become a 20-year saga, with heated lobbying both for and against the crossing.

Although not the first four-wheel-drive vehicle or the first designed for rough, multipurpose field use, the Jeep MB was built as an unusual combination of these and other features of modern vehicle design in the World War II era.
