Purdy and Henderson

Corydon Tyler Purdy

Purdy had been a draftsman and surveyor's assistant in Chicago, Milwaukee and Saint Paul and in Chicago, IL, in the early 1880s. Purdy specialized in bridge design and applied these skills to skyscrapers. He worked as a structural engineer on the thirteen story steel frame of the Tacoma Building, Chicago, IL, (Holabird and Roche, Architects). Purdy and Henderson opened a New York City office in 1894 and moved its operations there by 1896. The New York City office designed the structure for the Waldorf-Astoria Hotel in New York, NY. (Schultze and Weaver, Architects, 1893-1897). In 1899, Purdy supervised the start-up of a New York office for his friend, George A. Fuller (1851-1900). (Purdy maintained a professional relationship with the Fuller Company.) By 1900, Purdy and Henderson had obtained consulting work in Havana, Cuba and produced important buildings there including El Capitolio and the Hotel Nacional. By 1910, the office had in addition to its New York office, four branches including Havana, Cuba, Boston, MA, Chicago, IL, and Seattle, WA. During the Depression, Purdy and Henderson were involved in a race to build the world's tallest building, an American structure taller than the Eiffel Tower.[5] Purdy and Henderson closed after Purdy's death.

Purdy was a member, American Society of Civil Engineers; Member, Institute of Civil Engineers of Great Britain; Member, Western Society of Engineers; Member, Engineers' Club of New York; Member, University of Wisconsin Alumni Club of New York; Member, Arctic Club, Seattle, WA; He won the Telford Premium Medal, Institute of Civil Engineers, London, 1909.

Purdy was a writer and spoke at national events for professional groups like the Boston Society of Engineers. He gave keynote speeches and educational lectures at his alma mater (UW), Cornell University, and other schools of engineering study. Said Purdy:[5]

The days of wooden bridges and buildings, and heavy masonry are numbered. Iron and other metals are rapidly taking their place. Engineers of the future must know the names and uses of the different forms in which iron or steel is produced, and they should know when a channel can be used to better advantage than a beam, and when an angle bar will serve better than a plate. In other words, they should well understand the particular characteristic of every form and shape of iron or steel which makes that particular form, shape, or kind most valuable in any given place or for any given use.

Lightner Henderson

Henderson worked in 1890 for an engineering firm in Cleveland, OH. Purdy and Henderson incorporated in 1901. After incorporation, Henderson became the President of the corporation from 1901-1915. Purdy and Henderson worked on several buildings on the Eastern US, and on projects in San Francisco, CA, and Seattle, WA. In about 1900, Purdy and Henderson had offices in New York City, Boston, MA, Chicago, IL, Havana, Cuba and Seattle, WA.

Henderson was a member of Western Society of Engineers, 1891-1916.

Henderson attended the State Normal School in Millersville, PA. He obtained his B.S. in Civil Engineering from Lehigh University, Bethlehem, PA, in 1889.

An obituary by Corydon Purdy stated of Henderson:

His achievements of these years, from 1893 through two decades were notable, and mark him as one of the great structural engineers of his day. He was of a very retiring disposition and rather shunned the association of other men. On this account, he was not as widely known, and the quite remarkable character of the man was not as widely recognized as it would have been otherwise....Along with his analytical powers of mind, there was always a practical turn to it, which never was submerged by the complication or the laborious character of a difficulty. He did not arrive at irrational or impracticable conclusions. Simplicity was the distinguishing mark of his designing. It was these two qualities of mind combined that made him so successful in his profession.[7]
