The secret architecture of the world's most elite law firm
In short: Cravath is not just a law firm; it is a blueprint for corporate power. By perfecting a specific system of hiring and training, it shaped how American business operates. From securing patents for the telegraph to navigating the most complex global mergers, its influence is woven into the modern economy.
Founded in 1819 by Richard M. Blatchford, Cravath has spent over two centuries at the epicenter of American industrial and financial history. The firm’s early portfolio was a 'who's who' of innovation and infrastructure: it represented the Bank of England, secured patents for the telegraph and the sewing machine, and advised on the expansion of the Union Pacific and New York & Erie railroads. Even its early legal victories were foundational, such as the 1854 merger of Blatchford and William H. Seward—who later negotiated the 1867 purchase of Alaska—forming the bedrock of the firm's prestige.
The firm's defining characteristic is the 'Cravath System,' devised by Paul Drennan Cravath in 1899. This model revolutionized legal practice by prioritizing the hiring of high-achieving new law school graduates based on grades, followed by years of immersive apprenticeship in corporate law. For over a century, this system intentionally limited 'lateral' hires—lawyers moving from other firms—to maintain a cohesive culture of internal development. While the firm began to open its doors to more lateral partners in the 2000s, the core philosophy of cultivating talent from the ground up remains a hallmark of its identity.
Beyond corporate mechanics, Cravath has acted as a pivotal architect of American civil rights and constitutional law. Cravath attorneys prepared Supreme Court documents regarding the Freedom Rides throughout the 1960s, and John F. Kennedy requested their assistance. They assisted in establishing the Lawyers’ Committee for Civil Rights Under Law. They were also instrumental in launching the litigation that led to the Miranda warning. Today, the firm maintains this legacy of influence, ranking as the #1 firm in the United States in the Vault Law 100 for 2017 through 2026, while continuing to manage some of the world's largest mergers and antitrust challenges.
The firm's reach is global, with offices in New York, London, Washington, D.C., and Hong Kong (now closed). It manages the first U.S. IPOs of European companies and advises on multi-billion dollar deals, such as the $7 billion acquisition of Grail by Illumina and the merger of Paramount Global with Skydance Media. It remains a relatively small, elite operation of about 500 lawyers, operating with a level of exclusivity that mirrors the 'white-shoe' status it has held since the 19th century.
