In Memoriam: Ronald J. Gilson, Pioneering Corporate Law Scholar

Ronald J. Gilson, the Charles J. Meyers Professor of Law and Business, Emeritus, and one of the pioneering scholars of modern corporate law and governance, died October 12, 2026. He was 80.
Gilson joined the Stanford Law faculty in 1979 and took emeritus status in 2014. Over a scholarly career spanning nearly five decades, he helped establish corporate governance as a major interdisciplinary field, bringing economic analysis to traditionally doctrinal questions and reshaping how scholars understand corporations, financial markets, and the role of lawyers in business transactions.
In 1991, he began teaching at Columbia Law School as a visiting professor, joining its faculty in 1993 as the Marc and Eva Stern Professor of Law and Business. He maintained an unusual arrangement that allowed him to divide his academic life between Columbia and Stanford.
“Ron was a leader and scholarly pathbreaker in the true sense of the word,” said George Triantis, JSD ’89, the Richard E. Lang Professor of Law and Dean of Stanford Law School. “His foundational analyses and creativity opened new lines of inquiry that are now central to finance and business law. Scholars around the world celebrate his work, and those of us fortunate to know him will miss his energy, generosity as a colleague, and wise mentorship.”
Curtis J. Milhaupt, the William F. Baxter-Visa International Professor of Law, spent 18 years as Gilson’s colleague at Columbia Law School before joining Stanford. Their offices were next door to each other, and Milhaupt recalled watching Gilson continually pack and unpack boxes as he traveled between New York and Palo Alto.
“I often wondered how a man with so many demands on his time, whose door was always open to anyone who wanted to come in and talk, managed to produce so much pathbreaking scholarship,” said Milhaupt, who called Gilson one of his closest friends in academia.
He also remembered a man whose quiet demeanor belied the power of his thinking.
“From my perspective, Ron had two defining characteristics,” Milhaupt said. “The first was humility, embodied in his soft voice, so soft that you often had to lean in to hear him. Even at low volume, Ron spoke with precision, and his ideas lingered.” The second, Milhaupt said, was “intellectual curiosity, which drove his exploration of foreign legal systems and his theoretical approach to corporate law.”
Helping Create Modern Corporate Law
Michael Klausner, the Nancy and Charles Munger Professor of Business and Professor of Law, places Gilson among a small group of scholars who fundamentally changed how corporate law is understood and studied. He and Gilson became friends and running partners when Klausner was teaching at New York University and Gilson was at Columbia. Both also had clerked for the same federal appellate judge.

“In the early 1980s, Ron helped create the modern field of corporate law and corporate governance,” Klausner said. Before Gilson and fellow scholars Frank Easterbrook, Daniel Fischel, and Lucian Bebchuk began applying economic analysis to the field, corporate law scholarship had largely focused on traditional analysis of statutes and judicial decisions, Klausner said. In a series of groundbreaking articles, Gilson debated Frank Easterbrook and Dan Fischel on the role and value of defenses against hostile takeovers. These included “A Structural Approach to Corporations: The Case Against Defensive Tactics in Tender Offers” and “Seeking Competitive Bids Versus Pure Passivity in Tender Offer Defense.”
“Ron absolutely had the best of the argument,” Klausner said, adding that hindsight has only strengthened that assessment.
A few years later, Gilson published “The Mechanisms of Market Efficiency” with Reinier Kraakman, which provided a framework for understanding how information is incorporated into securities prices—a central element of finance theory that the finance literature had assumed without analysis, Klausner said. This too became a foundational work in business law.
Creating a “Deals” Curriculum
Gilson also initiated scholarly literature and a law school course in which economic analysis is applied to business transactions. In 1984, he published Value Creation by Business Lawyers: Legal Skills and Asset Pricing, in which he introduced a conception of business lawyers as “transaction cost engineers.” Gilson advanced a new understanding of the role of transactional attorneys as not merely negotiating favorable terms for clients, but structuring transactions that generate greater overall economic value.
Gilson co-developed a pioneering Deals course at Columbia in 1994, which applied economic analysis to the structure of real-world business transactions. He brought the course to Stanford, where he and Klausner taught it together in 2000. Klausner continues to teach Deals and co-authored a book based on the course’s subject matter in 2024. The approach has spread to law and business schools internationally.
“An Extraordinary Gift”

Born in 1946, Gilson earned his bachelor’s degree from Washington University in St. Louis in 1968 and his JD from Yale Law School in 1971. Prior to his academic career, he practiced corporate and securities law at the San Francisco firm Steinhart, Goldberg, Feigenbaum & Ladar. His experience as a practicing lawyer informed an academic career notable for connecting economic theory with the realities of business transactions.
Gilson’s research extended across corporate finance, mergers and acquisitions, venture capital, complex contracting, and comparative corporate governance. He authored more than 90 articles and major casebooks, including The Law and Finance of Corporate Acquisitions, with Bernard Black, JD ’82, and Cases and Materials on Corporations, with Jesse Choper and John Coffee.
Milhaupt, who collaborated with Gilson on four articles, considers those experiences among the most formative of his academic career.
“He had an extraordinary gift for framing research in ways that were both highly engaging and intellectually powerful,” Milhaupt recalled. “In discussing a project, Ron could offer a single phrase that captured the key insight behind an institutional development or empirical result. It was often an ‘Aha!’ moment for me: That’s how we should frame this project.”
Milhaupt singled out Gilson’s scholarship on controlling shareholders as particularly influential, including his 2005 paper, “Controlling Shareholders and Corporate Governance: Complicating the Comparative Taxonomy.” The paper was subsequently recognized as one of the top corporate and securities law articles of 2006 in a poll of scholars and earned him the European Corporate Governance Institute’s prize for best law working paper. Milhaupt noted that Gilson explored dimensions of concentrated shareholding that other scholars had overlooked. “It inspired a lot of follow-on research and is likely to be cited for decades to come.”
A Global Influence
Gilson helped establish the Global Corporate Governance Colloquia, a research partnership involving 12 leading universities across North America, Europe, and Asia. Its inaugural conference, chaired by Gilson, took place at Stanford Law School in June 2015.
In 2017, he received the Institute’s Allen & Overy Prize for his paper, “From Corporate Law to Corporate Governance,” an examination of the field’s evolution over half a century.
A tribute published by the European Corporate Governance Institute also recognized Gilson’s decades of leadership in international corporate governance research, including his work fostering collaboration among scholars, regulators, and policymakers across the United States and Europe.
Gilson was a fellow of the American Academy of Arts and Sciences and the European Corporate Governance Institute, a reporter for the American Law Institute’s Corporate Governance Project, and a senior fellow emeritus at the Stanford Institute for Economic Policy Research. He also served as independent chair of the boards of directors of the American Century Mountain View Family of Mutual Funds.
He is survived by his wife, Nina Gilson, and daughters Cassie Gilson, JD ’98, and Rebecca Gilson Wara.
