Early Life and Influences

Elizebeth Smith Freeman was born on August 26, 1892, in Warsaw, Indiana. From an early age, she exhibited an extraordinary aptitude for languages and a keen interest in puzzles. Her father, a minister, instilled in her a passion for intellectual pursuits, while her mother, a teacher, fostered her love for reading and writing.

A Chance Encounter with Cryptanalysis

In her early twenties, Elizebeth worked as a clerk in Chicago. In 1917, a chance encounter with a newspaper article about the sinking of the Lusitania piqued her interest in cryptography. She wrote to the U.S. War Department, offering her services as a codebreaker. To her surprise, her offer was accepted, and she was assigned to the Military Intelligence Division.

Pioneering Codebreaking Techniques

Elizebeth quickly demonstrated her exceptional skills in cryptanalysis. She developed innovative techniques for deciphering complex codes and ciphers. Her meticulous attention to detail and ability to identify patterns and anomalies enabled her to unravel even the most challenging encrypted messages.
