The groundbreaking contributions and initial advancements made by women in the field of cryptanalysis.

Mundy highlights the crucial contributions of many women adept in cryptanalysis during the early 20th century, which laid the groundwork for the significant enlistment of female codebreakers during the Second World War. In a time when career opportunities for educated women were limited, their quest for intellectual growth, eagerness for novel challenges, and ambitions for financial independence lured them into the intricate and specialized field of cryptography. Their contributions transformed cryptanalysis from a niche scholarly discipline into an essential component of military tactics and governmental policy, laying the groundwork for sophisticated codebreaking operations that were pivotal throughout the Second World War.

Elizebeth Smith Friedman played a pivotal role in the development of cryptology.

Elizebeth Smith Friedman pioneered the involvement of women in the complex realm of cryptanalysis. Mundy narrates a tale characterized by fortuitous events, resolute spirit, and seizing chances during a time when women were often dissuaded from engaging in intellectually demanding pursuits. Friedman's example paved the way for people like Wilma Berryman to make substantial contributions that helped shorten the duration of the war.

Elizebeth Friedman played a pivotal role in revealing hidden schemes through her use of a specific code-breaking technique.

Elizebeth Smith, who had a passion for literature and had previously taught school, ventured into the field of codebreaking in 1916 while seeking a job at the Newberry Library in Chicago. An employment agency suggested she apply to an eccentric multi-millionaire, George Fabyan, who maintained a private "think tank" called Riverbank Laboratories. Fabyan enlisted Smith for an intellectual project based on the assumption that hidden messages were embedded by Sir Francis Bacon within the typography of Shakespeare's First Folio. The method was centered on a cryptographic technique, initially conceived by Bacon, known as a "biliteral" cipher. The biliteral cipher utilizes two unique symbols or characters to represent each letter of the alphabet, allowing for the safe encryption of any word in the language. Smith and William Friedman, although finding the Bacon theory to be without merit, were nonetheless thoroughly captivated by the historical exploration of cryptology.

As their skills sharpened, they were tasked with deciphering communications that exposed a conspiracy by Indian nationalists in collaboration with German operatives to destabilize British rule in India. Smith and Friedman were instrumental in deciphering the communications that provided a solid foundation for subsequent legal convictions. The crucial part played by Smith in employing codebreaking as a tool to counteract espionage and political scheming was overshadowed when William appeared in court to give testimony.

Context

• The Newberry Library in Chicago is an independent research library, which was established in 1887. It is known for its extensive collections in the humanities, including rare books and manuscripts, which might have attracted someone with Elizebeth's literary background.
• George Fabyan was a wealthy businessman and philanthropist who had a keen interest in scientific research and cryptography. He used his resources to fund Riverbank Laboratories, one of the first private research facilities in the United States.
• The belief that Sir Francis Bacon wrote Shakespeare's works is known as the Baconian theory. Proponents argue that Bacon used ciphers to embed his authorship within the texts, a claim that has been widely discredited by mainstream scholars.
• The period when Smith and Friedman were active was marked by global conflict, which spurred advancements in cryptology as nations sought to secure their communications.
• Various groups in India were actively seeking independence from British rule. Some factions were willing to collaborate with foreign powers like Germany to achieve their goals.
• The deciphered communications provided concrete evidence that could be used in court to prosecute individuals involved in espionage or treason. This was significant because it transformed cryptographic work from theoretical exercises into practical tools for law enforcement and national security.
• Court testimonies during this period were often dominated by men, who were more frequently seen as authoritative figures. This could have influenced the decision to have William testify, despite Elizebeth's significant contributions.

Elizebeth Friedman transformed cryptanalysis from a purely academic pursuit into a crucial tool for wartime efforts.

Elizebeth Friedman, alongside her spouse William, saw a significant increase in demand for their cryptanalytic skills as World War I commenced. A significant number of military personnel received their training at Riverbank. Elizebeth's success in decoding the secret communications of bootleggers during the interwar period not only elevated her status in the fight against criminal activities but also...
