Barbarians at the gate

The Fall of RJR Nabisco

Bryan Burrough

Barbarians at the Gate is a detailed and engaging narrative about the takeover of RJR Nabisco in 1988. Written by investigative journalists Bryan Burrough and John Helyar, the book provides an unprecedented look at the financial operations and social history of the time. It centers around F. Ross Johnson's plan to buy out RJR Nabisco, which led to a bidding war involving prominent figures like Henry Kravis and Ted Forstmann. The book includes a new afterword that updates the story twenty years after the deal, tracing the subsequent success and failure of those involved and the impact of the story on the world.

Liar's poker

Michael Lewis

Liar's Poker is a non-fiction, semi-autobiographical book that details Michael Lewis's three-year tenure at Salomon Brothers, one of Wall Street's premier investment firms in the 1980s. The book provides a behind-the-scenes look at the culture of bond traders, highlighting the frat-boy camaraderie, killer instincts, and high-stakes games of bluffing and deception. Lewis describes the creation and use of mortgage bonds, the excessive bonuses, and the ruthless competition among traders. The narrative also touches on the author's disillusionment with the industry, leading to his resignation and transition into financial journalism.

In this special episode, my friend—and fan-favorite guest—Dr. Peter Attia takes the mic as guest host. Peter sits down with legendary trader John Arnold, widely considered the greatest energy trader of all time. Today, through his foundation Arnold Ventures, John applies the same rigorous thinking to some of America’s toughest social challenges—criminal justice reform, healthcare policy, and K–12 education, to name just a few. This interview originally aired on Peter’s excellent podcast The Drive. You can check it out at PeterAttiaMD.com, or subscribe to The Drive wherever you get your podcasts.
