A leading scholar in law and economic theory. Rest in peace.
Columbia Law mourns the loss of Professor Emeritus Ronald J. Gilson, an expert on law and economics who taught at Columbia Law School for more than three decades. He died on October 12.
A distinguished academic, Gilson’s scholarly contributions spanned corporate governance, finance, capital markets, and mergers and acquisitions. Drawn from his experience in private practice, his work helped set in motion a transformation in legal education, including through the development of Columbia Law’s Deals course—a model for law and business schools around the world.
“Through a rare combination of intellectual ambition, analytical rigor, and prior experience as a practicing lawyer, Ron was able to bridge the divide between theory and practice perhaps more successfully than any academic of his generation,” said Dean Daniel Abebe. “It is clear that Ron’s influential scholarship has left an indelible imprint, both for those who study the law and those who practice it.”
