Thames Tunnel
Society: ASCE Main Category: Civil Sub Category: Tunnels Era: 1840-1849 DateCreated: 1843 Beneath the Thames River London State: Zip: Country: UK Website: http://www.asce.org/Project/Thames-Tunnel/ Creator: Brunel, Marc Isambard , Brunel, Isambard Kingdom

By the turn of the 19th century, London's streets were clogged with traffic. Over 3,700 passengers used the Thames River's main boat crossing each day, while wagons and carts were forced to cross via the London Bridge, two miles away. Building a bridge would further impede shipping on the already-crowded Thames; a tunnel was the obvious alternative.

The first attempt at a tunnel in the present location began in 1807. The excavation had proceeded only 1,000 feet-using traditional mining methods-when crews reached a layer of quicksand and were forced to stop.

Society: ASME Main Category: Mechanical Sub Category: Minerals Extraction & Refining Era: 1800-1829 DateCreated: 1828 Furnace Town Living Heritage Museum Snow Hill State: MD Zip: 21863 Country: USA Website: http://www.asme.org/about-asme/history/landmarks/topics-m-z/minerals-extraction-and-refining/-159-nassawango-iron-furnace-%281828%29 Creator: Maryland Iron Company
This furnace was the focal point of a pre-Industrial Revolution industry town, one of hundreds of furnaces that thrived and failed in the 19th century. The Maryland Iron Company (incorporated 1828) built this furnace along the Nassawango Creek roughly four miles northwest of the Pocomoke River to produce pig iron by the cold-blast process. In 1836-37 the furnace changed ownership several times, until Thomas Spence of Worcester County purchased it and began producing pig iron at a rate of 700 tons a year. Spence is credited with the installation of the hot-blast stove.

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.

Victoria Dutch Windmill
Society: ASME Main Category: Mechanical Sub Category: Wind Power Production Era: 1940-1949 DateCreated: 1944 Memorial Park Victoria State: TX Zip: 77901 Country: USA Website: http://www.asme.org/about-asme/history/landmarks/topics-m-z/wind-power-production/-151-victoria-dutch-windmill-%281840s%29, https://www.asme.org/getmedia/34e19ef6-403f-4bb4-8a57-92c17d01716e/151-Victoria-Dutch-Windmill-1840s.aspx Creator: Meiss, Fred , Fiek, Otto

This is an old technology brought here by new immigrants. It represents the beginning of modern life in a hard wilderness. This wind-powered gristmill was built in 1870 by Fred Meiss, Jr., and Otto Fiek near Spring Creek, from parts of the first windmill in the new state of Texas, erected by E.G. Witte. The millstones are the ones Witte imported from Europe and are believed to be one of the earliest sets in the United States to survive.

Greens Bayou Generator Plant
Society: ASME Main Category: Electric, Mechanical Sub Category: Steam Era: 1940-1949 DateCreated: 1949 13300 West Bellfort Avenue Houston State: TX Zip: 77099 Country: USA Website: https://www.asme.org/about-asme/who-we-are/engineering-history/landmarks/154-greens-bayou-generator-plant Creator: Sinton, Walton

On April 21, 1949, a completely outdoor turbine-generator was placed into commercial operation at the Greens Bayou electric power plant--the first fully outdoor unit to operate in the United States. The demand for unprecedented quantities of electricity after World War II pressed utilities to provide addition power quickly. The outdoor design, unlike the traditional large turbine hall, resulted in significant reductions in the cost per kilowatt to build the plant.

In 1907, John Fritz, known as the "Father of the Steel Industry in the United States," rejoined the Lehigh University Board of Trustees after an absence of a decade. He began the development of what would prove to be his greatest gift to Lehigh: a modern engineering laboratory and funding for its construction.

Fresno Scraper
Society: ASME Main Category: Civil Sub Category: Agriculture Era: 1880-1889 DateCreated: 1883 Fresno State: CA Zip: Country: USA Website: http://www.asme.org/about-asme/history/landmarks/topics-a-l/agriculture/-158-fresno-scraper-%281883%29 Creator: Porteous, James

The Fresno scraper established the basis for the modern earthmoving scraper, being able to scrape and move a load of soil, then discharge it at a controlled depth. It quadrupled the productivity of manual labor, replacing hand shoveling of earth into horse carts.

Eddystone Lighthouse

An early image of the James Douglass lighthouse, with the stump of the Smeaton-designed building beside it.  

Eddystone Lighthouse is located in the English Channel, 14 miles south of Plymouth, England. The reef upon which it stands was the source of many shipwrecks... and many lighthouses, the first of which was built in 1698. The first three lighthouses were wooden, and suffered the fate of sea storms. John Smeaton  built the fourth lighthouse in 1759 of Cornish granite.
