Mayer Brown (Mayer Brown International LLP) is an international law firm. With offices in 24 cities across the Americas, Asia, Europe and the Middle East, Mayer Brown has approximately 1,500 lawyers and by revenue is the 17th largest law firm in the world. The firm advises many Fortune 100, FTSE 100, DAX and Hang Seng Index companies and more than half of the world’s largest banks. The three firms that now form the core of Mayer Brown were all founded in the 19th century. The US portion of the firm was founded in 1881 in Chicago, by Adolf Kraus and Levy Mayer, and was shortly thereafter known as Kraus, Mayer & Brackett. After several changes in name to reflect its changing membership the firm eventually became known in the US as Mayer, Brown & Platt. The English portion of the firm, Rowe & Maw, was established in 1895 in London and operated under that name until joining with Mayer, Brown & Platt in 2002 to form Mayer, Brown, Rowe & Maw. In 2007 the amalgamated firm shortened its name to Mayer Brown. Johnson Stokes & Master was formed in 1863 in Hong Kong and is today known as Mayer Brown JSM after merging with Mayer Brown in 2008.
