The Woman All Spies Fear

Amy Butler Greenfield's biography of Elizebeth Smith Friedman reveals the remarkable story of a woman whose contributions to American cryptography and national security remained largely unknown for decades. Through meticulous research and access to previously classified documents, Greenfield brings to light the extraordinary achievements of a codebreaker who worked in the shadows while shaping the course of history.

Elizebeth Smith Friedman began her career in an unexpected way, hired by the eccentric millionaire George Fabyan to work at his Riverbank Laboratories in Illinois. What started as work on Shakespearean ciphers evolved into groundbreaking cryptanalysis during World War I. At Riverbank, she met William Friedman, whom she would marry, and together they would become two of the most important figures in American codebreaking. However, while William's contributions eventually received recognition, Elizebeth's work remained classified and forgotten for generations.

Greenfield chronicles how Friedman became instrumental in fighting Prohibition-era smugglers during the 1920s and 1930s. Working for the Treasury Department and Coast Guard, she decrypted thousands of messages from rum-running operations, helping to dismantle major criminal networks. Her testimony in court was crucial in securing convictions, and her expertise made her an invaluable asset to law enforcement agencies struggling to combat sophisticated smuggling operations that used increasingly complex codes.

The book details Friedman's critical role during World War II, when she worked against Nazi spy rings operating in South America. Her ability to break enemy codes helped expose Axis intelligence networks and protect Allied interests throughout the Western Hemisphere. The Doll Woman case and other counterintelligence operations showcased her exceptional analytical skills and persistence. Despite the significance of her work, much of it remained classified long after the war ended, contributing to her historical invisibility.

Greenfield explores the personal costs of Friedman's secret life. The demands of classified work meant she could not discuss her achievements publicly or receive recognition for her contributions. The biography examines how she navigated a male-dominated field, often seeing her work attributed to others or simply disappearing into classified files. The strain of maintaining secrecy while watching others receive credit for cryptographic advances shaped both her professional experience and personal life.

The author draws on FBI files, personal papers, and declassified government documents to construct a comprehensive portrait of Friedman's career. Greenfield's research benefits from the gradual declassification of materials that occurred decades after Friedman's death in 1980, allowing for a fuller accounting of her contributions than was previously possible. These sources reveal not only her technical brilliance but also her determination to continue working despite the obstacles she faced.

The narrative places Friedman's work within the broader context of intelligence history and the development of American cryptography. Greenfield explains complex cryptographic concepts in accessible terms, making the technical aspects of codebreaking understandable without oversimplification. The book demonstrates how cryptanalysis evolved from a relatively obscure field into a crucial component of national security.

Greenfield also addresses the gender dynamics that shaped Friedman's career and legacy. As one of the few women in cryptography during her era, she faced skepticism and discrimination while consistently proving her capabilities. The book examines how her contributions were systematically minimized or erased from official histories, reflecting broader patterns of how women's achievements in science and national security were treated during the twentieth century.

The biography succeeds in rescuing Friedman's story from obscurity and establishing her rightful place in the history of cryptography and intelligence work. Greenfield's thorough research and clear prose make this complex subject matter engaging and accessible. The book serves as both a compelling biography and an important historical corrective, documenting achievements that deserve recognition alongside those of her more famous contemporaries.

For readers interested in World War II history, cryptography, women's contributions to science and national security, or biographical accounts of overlooked historical figures, this book offers substantial value. Greenfield has produced a well-documented and thoughtfully written account that honors Friedman's legacy while acknowledging the institutional forces that kept her work hidden for so long. The woman all spies fear stands as an essential contribution to understanding the hidden history of American intelligence and the remarkable individuals who worked behind the scenes to protect national security.
