20th Century The firm was founded in January 1934 in Los Angeles, California, by
Dana Latham and Paul Watkins. Latham's practice focused on state and federal
tax law, and he eventually served as Commissioner of the
U.S. Internal Revenue Service under President
Dwight Eisenhower. Watkins's practice focused primarily on labor. At first, the firm grew slowly, with only 19 attorneys employed as of 1960. In February 1978, the firm expanded into
Washington, D.C., by adding
Carla Anderson Hills as a named partner. Hills had left her role as
U.S. Secretary of Housing and Urban Development in the
Ford administration the prior year, and she oversaw the firm's expansion into
administrative law. This branch was initially staffed with a mix of attorneys drawn from the Los Angeles office and new hires from the upper ranks of federal agencies. In the latter half of the twentieth century, Latham quickly expanded its national and international presence. The firm opened offices in
San Diego (1980),
Chicago (1982),
New York City (1985),
San Francisco (1990),
London (1990),
Moscow (1992),
Hong Kong (1995),
Tokyo (1995),
Silicon Valley (1997), and
Singapore (1997). Amid the global recession in 2009, the firm laid off 190 lawyers and 250 paralegal and support staff, representing twelve percent of the firm's total associates and ten percent of the support staff. At a time when many firms were conducting layoffs, the term "Lathamed" became legal slang for being laid off. In 2018, Latham was the first law firm to report more than $3 billion in gross revenue. It was briefly the highest-grossing law firm in the world, but has since lost the number one spot to
Kirkland & Ellis. In August 2023, Latham announced the decision to close its
Shanghai office amid consolidation of its operations in China. Amid clashes at some college campuses, following the onset of the
2023 Israel-Hamas war, Latham & Watkins was among a group of law firms who sent a letter to 14 American law school deans denouncing
anti-Semitism,
Islamophobia, and
racism. During the
targeting of law firms and lawyers under the second Trump administration, in April 2025, the firm agreed to a deal with
Donald Trump, committing to provide $ of
pro bono legal work on behalf of causes endorsed by Trump, in order to avoid punitive
executive orders. As a result of the settlement, companies, including
Morgan Stanley and
Microsoft, moved their legal work to other firms that had not settled with the administration. == Rankings ==
