Sidley Austin LLP is a global law firm headquartered in Chicago, tracing its origins to a Chicago practice founded in 1866. The firm’s visual identity consists of a wordmark lockup that pairs the “Sidley” name with “Austin” beneath it, set in a dark blue tone. The current firm name and identity emerged from a 2001 merger between Chicago-based Sidley & Austin and New York-based Brown & Wood, with the combined entity operating as Sidley Austin Brown & Wood until the name was shortened to Sidley Austin in 2006.
Design and History
The firm’s roots trace to 1866, when Norman Williams and John L. Thompson formed the partnership Williams & Thompson in Chicago. The Sidley name entered the firm’s title in 1900, when William Pratt Sidley, who joined as a young lawyer in 1892, became a named partner.[1] Over the following decades, a series of mergers and name changes shaped the firm, including a 1972 consolidation with Leibman, Williams, Bennett, Baird & Minow that produced Sidley & Austin.[2]
The modern Sidley Austin identity dates to May 2001, when Sidley & Austin merged with Brown & Wood, a New York firm founded in 1914.[3] The merged firm initially operated as Sidley Austin Brown & Wood LLP before rebranding to Sidley Austin in 2006.[4] The current wordmark reflects this shortened name, presenting “Sidley” and “Austin” as a two-line lockup without pictorial symbols or crest elements.
Meaning and Symbolism
The Sidley Austin wordmark is rendered in a deep blue tone. Brand color data associated with the firm lists a primary blue with the hex code #005D86, a shade sometimes identified as “Orient.”[5] The firm’s identity relies on this restrained, single-color wordmark treatment rather than on iconography or emblematic devices, consistent with the conservative visual conventions common among large law firms. No official documentation of symbolic meaning behind the color or wordmark design has been published by the firm.
Typography and Design
The Sidley Austin lockup uses a serif typeface for both lines of the wordmark, with “Sidley” set in larger, bolder letterforms above “Austin” in a smaller, lighter weight. The typography is traditional and understated, with no decorative elements, monograms, or graphic marks accompanying the name. The firm applies this wordmark consistently across its website, legal documents, and office signage, with the blue color serving as the primary brand identifier across communications.[5]
