The legal architecture behind some of America's most controversial headlines
In short: From defending espionage suspects to navigating the opioid crisis, Debevoise & Plimpton operates at the apex of high-stakes law. This white-shoe firm doesn't just practice law; it shapes the legal framework of global corporations, government investigations, and some of the most polarizing corporate scandals of the modern era.
Founded in 1931 by Eli Whitney Debevoise and William E. Stevenson, the firm quickly established a pedigree of elite influence. Its early trajectory was marked by high-profile cases, such as the 1930s bankruptcy of Ivar Kreuger and the 1950s perjury trials of Alger Hiss. The firm’s leadership has historically moved between the courtroom and the highest levels of government; for instance, partners have served as U.S. Ambassadors, UN Representatives, and high-ranking judicial officers. The firm's modern portfolio highlights a complex intersection of corporate power and public controversy. It notably represented four members of the Sackler family, the owners of Purdue Pharma. Amid the opioid epidemic, the firm received more than $11.4 million out of a total $17.5 million legal spend from Purdue Pharma.
Additionally, the firm has been tasked with sensitive institutional oversight, such as investigating student misconduct at Columbia University in 2024 and establishing internal AI governance policies in 2023. Structurally, the firm is undergoing a significant evolution. For decades, it was one of the last major firms to use a lockstep seniority-based compensation system. However, in June 2025, it introduced a non-equity partner tier to align with the broader Am Law 200 landscape. This shift reflects a broader trend in the legal industry toward modernizing partnership structures while maintaining a reputation for handling the most complex international arbitrations and white-collar investigations.
