How a journalist discovered that political power is not found at the ballot box

In short: Robert Caro spent half a century investigating how power truly functions in America. After witnessing an unelected official override democratic processes, he abandoned conventional reporting to write massive, definitive biographies of Robert Moses and Lyndon B. Johnson. Now, his personal archives are being preserved to reveal the mechanics of influence.

Robert Caro’s career shifted in the 1960s when he realized his understanding of democracy was flawed. While working as an investigative reporter, he campaigned against a bridge project championed by urban planner Robert Moses. Despite Caro’s reporting, the state legislature voted to approve the project. This moment was transformational: Caro realized that while he believed power resided in the ballot box, Moses—who had never been elected to anything—wielded enough influence to override the state’s democratic institutions. This realization launched his lifelong mission to uncover how political power actually works.

This pursuit resulted in The Power Broker, a 1,162-page biography of Moses published in 1974, and a multi-volume series on Lyndon B. Johnson. Originally planned as a three-volume work announced in 1975, the Johnson project expanded to four volumes by 1990 and eventually to five. Caro, now 89, remains dedicated to completing this final installment. His process is defined by exhaustive research; his archives at the New York Historical contain approximately 120 boxes and 100 linear feet of material, including notebooks from interviews conducted as early as 1967.

Caro’s approach to history is rooted in the belief that figures must be brought to life to understand the mid-20th century. He emphasizes the importance of silence, noting that people have a natural urge to fill it, which often leads them to reveal more than intended. He avoids discussing his own legacy, focusing instead on ensuring his readers understand the reality of power—how it affects lives for better or worse—rather than the simplified versions found in textbooks. By securing a permanent exhibition for his archives, he ensures these insights remain accessible to future generations.
