Excerpt: 

Historic Pittsburgh is a digital collection that provides an opportunity to explore and research the history of Pittsburgh and the surrounding Western Pennsylvania area on the Internet. This website enables access to historic material held by the University of Pittsburgh's University Library System, the Library & Archives of the Historical Society of Western Pennsylvania at the Senator John Heinz Pittsburgh Regional History Center, and the Carnegie Museum of Art. The project represents a model of cooperation between libraries and museums in providing online access to their respective materials.

Annotation: 

This site chronicles the history of the city of Pittsburg. The site includes a timeline that offers a general overview with brief entries, but the researcher who wants in-depth information can head to the collection of more than 500 full-text books, thousands of images, and hundreds of maps available on the site. The books and images are searchable and the maps are indexed with lists of important landmarks linked to their location on each map. Census records are also available for the mid-nineteenth century.

Excerpt: 

Gentlemen:
It gives me great pleasure to be enabled to report the Niagara Suspension Rail Way Bridge complete in all its parts. The success of this work may now be considered an established fact. The trains of the New York Central, and of the Great Western Rail Road in Canada, have been crossing regularly since the 18th of March, averaging over 30 trips per day.
One single observation of the passage of a train over the Niagara Bridge, will convince the most skeptical, that the practicability of Suspended Railway Bridges, so much doubted heretofore, has been successfully demonstrated.

Excerpt: 

From southeast to northwest, Cleveland is traversed by the winding Cuyahoga river valley, which, while it provides the railroads with an effective entrance to the city, cuts it into two distinct districts as far as vehicular traffic is concerned. To provide crossings over the river and its wide valley, several bridges have been builds, notably the Detroit-superior Bridge near the lakefront and the central viaduct to the south. After 25 years of study on viaduct to connect Lorain avenue on the west of the river with the district to the east, in The Course of which time the project was once abounded after bonds had actually been voted for construction, the citizens of Cleveland are opening, the first week in the November, a $6500000 viaduct 5,865 ft. long, with its eastern terminus at central avenue. Dr. Watson's interest in the project has been continuos since its inception.

Excerpt: 

In developing the STRUCTURAL ENGINEERING SLIDE LIBRARY as a comprehensive resource for teaching structural and architectural engineering at college and university level, I felt there was a need to devote a volume to the work of one structural design company. Leonhardt, Andrä and Partners of Stuttgart, Germany, was an ideal choice for this project. One of Europe’s leading structural design companies, its staff has been on the leading edge of many developments in engineering over the past 40 years. Their name has been particularly associated with the development of incrementally launched bridges, cable-stayed bridges, cable-net structures, and prestressed concrete television towers.

Annotation: 

The University of California at Berkeley has compiled a sizeable archive of slides of work by Leonhardt, Andrä and Partners of Stuttgart, Germany. Images are categorized according to their architectural characteristics, the type of material used, or the type of structure pictured. Text content also details some of the structures pioneered by the architecture firm. Useful for architectural case studies and research.

Excerpt: 

WATSON, WILBUR J. (5 Apr. 1871-22 May 1939), a civil engineer, especially eminent in bridge design, was born in BEREA to David R. and Maria (Parker) Watson. Receiving his B.S. from the Case School of Engineering, Watson developed a carefully stated philosophy of the relationship between engineering and aesthetics and used structural and reinforced concrete to produce some of the most beautiful BRIDGES in northern Ohio. He helped set standards for bridge construction across the country. While employed by OSBORN ENGINEERING CO. in Cleveland, Watson was designing bridges as early as 1898. Marrying Harriett Martha Barnes in 1900, Watson founded his own firm, Wilbur J. Watson & Associates, in 1907.

Wrought Iron Bridge Company

Author: 
Digital Bridges, Lehigh University
Excerpt: 

The construction of durable Iron Highway Bridges instead of perishable wooden structures – securing, as it does an ornamental and permanent improvement to the public highways, and avoiding their frequent obstruction for the repair or rebuilding of wooden bridges failing from decay, storm or fire – has become an imperative public want, wherever trial has been made of properly designed and constructed work.

Annotation: 

This Digital Bridges page contains a facsimile of the illustrated pamphlet of wrought iron bridges built by this Ohio Company. However, unlike several other period bridge-building company pamphlets, the Wrought Iron Bridge Company focuses on images rather than text, leaving an aesthetic record of railroad bridges where other pamphlets tend to give a technical record. A worthwhile primary source for those seeking graphic representations of 19th century bridges.

Author: 
Kathryn Dan, Manager and University Archivist, Monash University
Excerpt: 

Debate about the descriptor for Victoria's second university was not prolonged and through an enabling Act 1958, Monash University became one of a very few universities in the world named after a military hero. Of German-Jewish immigrant stock Sir John Monash was Australian, indeed Victorian, to the core and is still regarded as Australia's greatest fighting General. He was possessed of such diverse talents that his scholastic failures as a young man serve to remind us that even great men are human and that focus, application and determination are key ingredients for success as much in academia as in other spheres of life.

Annotation: 

This online exhibition features biographical information about engineer John Monash, from his early life, to his time as a soldier, to his lengthy professional life in Australia. However, the true gem of the site is the collection of photographs and other memorabilia donated by the Monash family, such as baby photographs of Monash and scanned facsimilies of his commisions from the Australian government. Though the exhibition has only four web pages of content, the Monash artifacts are scattered on every page, and they are a perfect accompaniment to the data on Wabash himself.

Author: 
Digital Bridges, Lehigh University
Excerpt: 

The theory of the equilibrium of arches, until of late years, commanded but little attention from practical men, partly owing to the fact that, since it was derived from observations of their own failures and successes, it came rather too late to be of much service to them, but chiefly owing to the form in which it was presented by mathematicians, who, by giving a fictitious importance to insignificant matters, effectually obscured the broad truth, that the whole question was essentially a comparatively simple problem of weight and leverage.

Annotation: 

This archived Digital Bridges document reviews some engineering techniques on the forefront of bridge-building technology in the late 19th century. Like many similar period documents, the bulk of the work is textual and the sentences too convoluted for casual reading; the document was likely intended for readers already educated in the subject. However, there are also some useful lithographs in the book, and the entire document shows the direction in which engineers believed bridge-building would be headed in the coming years.

Excerpt: 

Since the presentation of our last album in 1873, the rapid increase in the variety and amount of out business, in the design and manufacture of bridges and of all kinds of structures of iron and steel, renders it necessary for us to exhibit to the public, and to our friends and customers particularly, the present state of constructive engineering as existing at the works of the Phoenix Bridge Company.

Annotation: 

The Digital Bridges project at Lehigh University has archived and posted this 1885 publication in html, pdf, and tiff formats. The summary of affairs of the Phoenix Bridge Company and its subsidiaries provides a fascinating look into bridge and railroad technology in the 1880s. Though the majority of the book is text, many clear photographs of the company's work are interspersed between the typed pages. Any researchers of railroad and bridge history, as well as of the business of transportation, would do well to examine this document. Also see "Album of Designs of the Phoenixville Bridge-Works."
