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.
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.
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.
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."
the King Iron Bridge & Manufacturing Company of Cleveland, Ohio (later the King Bridge Company) was founded by Zenas King in 1858. Many of the Company's bridges were used during America's expansion West in the late 1800's and early 1900's and some of these bridges are still standing today. The bridge pictured on this website represent some of the beautiful King iron bridges. We are trying to locate any existing ones in order to preserve these pieces of American history.
This site chronicles research on the King Iron Bridge and Manufacturing Company of Cleveland, Ohio. It includes an extensive history of company operations, descriptions and photographs of most bridges the company has constructed, accounts of the different owners, a list of King Bridge preservation efforts, scanned pages from century-old catalogs, contact information for bridge experts, a collection of King memorabilia, an online forum, and far more. Author Allan King Sloan has created a full compendium of the company's history and a snapshot of the bridge industry in the 19th century.
Mid-19th century advertisement for Wendell Bollman from a City Directory , a civil and constructing engineer noted for his truss bridges. An engraving in the ad. shows a truss bridge with a Civil War era locomotive about to cross it. The address for Bollman's works was given as Clinton Street and Second Avenue, Canton.

Born in Berne, Switzerland, future structural engineering visionary Robert Malliart earned a degree in civil engineering from the Federal Polytechnical Institute in Zurich in 1894. Malliart established his own design-construction company in 1902 and moved the firm to Russia in 1912, only to see it fail during the Russian Revolution five years later.
In a two-year span before the move to Russia, Malliart entered five major bridge competitions, although judging bodies typically preferred bridges more conventional than young Malliart’s. Regardless of the design competitions, continued innovative bridge designs produced notoriety for him.
This page is one in a series of biographies about famous civil engineers. The American Society of Civil Engineers (ASCE) follows Malliart from his Russian emigration, through his invention of the deck-stiffened arch bridge, and up to the completion of the Salginatobel Bridge, his longest bridge. A picture and a description of the structure appear after clicking on the Salginatobel's name. Clicking the "resources" link brings up a modicum of recommended reading to spur on any aspiring researchers.

Ralph Modjeski, considered "America's greatest bridge builder", was born in Bochnia, near the city of Krakow, Poland on January 27, 1861. He immigrated to America at the age of 15 with his mother, famous Shakespearean actress, Helen Modjeska, in July, 1876. Even though Modjeski seemed destined to become an accomplished concert pianist, he went on instead to become a highly successful civil engineer and "one of the twentieth century's most famous designers and builders of bridges". In 1929, Modjeski was awarded the John Fritz Gold Medal, the highest American engineering medal, with a citation for his genius in combining strength and beauty. He was also honored by the Pennsylvania state legislature in 1966 by a resolution citing him as one of America's "greatest inventors".
