History

[edit]

Waddell & Harrington was formed in 1907 as a partnership between John Alexander Low Waddell and John Lyle Harrington and was based in Kansas City, Missouri, but had offices in Portland, Oregon, and Vancouver, British Columbia. The company designed more than 30 vertical-lift bridges for highways and railroads. After Howard's partnership, Waddell & Harrington eventually became Harrington, Howard & Ash. In 1941, it changed its name to Howard, Needles, Tammen & Bergendoff when Enoch Needles, Henry Tammen & Ruben Bergendoff joined as partners. In 1975, it merged with Kivett and Myers to form a sports architecture practice. In 1982, it acquired the rail firm of Thomas K. Dyer adding track, signal, communications and traction power to its portfolio, thus positioning the firm to serve the rail industry. In 1993, it formally changed its name to HNTB Corporation. In 2000, the firm became employee-owned.[6]
