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 (formerly Mayer Brown JSM) after merging with Mayer Brown in 2008.[6]


The firm has offices in Beijing, Brussels, Charlotte, Chicago, Düsseldorf, Dubai, Frankfurt, Hanoi, Ho Chi Minh City, Hong Kong, Houston, London, Los Angeles, Mexico City, New York City, Palo Alto, Paris, San Francisco, Shanghai, Singapore, Tokyo, and Washington DC; and, in association with Tauil & Chequer Advogados, offices in Brasília, Rio de Janeiro, São Paulo, and Vitória.

Role in Refco Inc. collapseEdit

Refco was a New York-based broker of commodities and futures contracts. It filed for one of the biggest bankruptcies in the USA history in 2005, after evidence of major accounting fraud surfaced.[26] In the wake of the collapse, a lawsuit was filed against Mayer Brown for aiding Refco executives' theft of more than $2 billion.[27] In November 2012, Joseph Collins, a former partner at the Mayer Brown, was found guilty on multiple charges of conspiracy and fraud for his role in preparing Refco's IPO.[28][29] The law firm itself agreed to pay an undisclosed sum to settle the legal claims against it.[30]
