An American pioneer in the field of cryptology—the study of writing and solving secret codes—William Friedman is known for his distinguished career as an expert codebreaker with the U.S. Army during World Wars I and II. But although Friedman is one of the biggest names in cryptanalysis—he coined the word itself—historians often skip over the fact that his wife, Elizebeth, was every bit as skilled a codebreaker. Her accomplishments have been (sometimes deliberately) kept from the spotlight.

The youngest of nine kids in a Quaker family, Elizebeth Friedman (née Smith) was born in rural Indiana in 1892. (Her mother spelled her name unusually, swapping out the a for another e, reportedly because she disliked the nickname “Eliza.”) Young Elizebeth was bright and displayed a talent for languages, and was determined to go to college despite the discouragement of her father—so determined that she eventually ended up borrowing tuition from him at a 6 percent interest rate. After starting out at Ohio’s Wooster College in 1911, she finished her degree at Hillsdale College in Michigan, majoring in English lit. She also studied German, Greek, and Latin at Hillsdale, and it was there that she discovered her lifelong love for Shakespeare.

After graduation and a brief spell as a substitute principal at an Indiana high school, Elizebeth traveled to Chicago in 1916 and visited the Newberry Library, where Shakespeare’s First Folio was on display. There—having quit her principal job out of boredom—she asked the librarians if they knew of any research or literature jobs available. Within minutes, she was being introduced to the eccentric George Fabyan, who ran a 500-acre private research facility called Riverbank in nearby Geneva, Illinois. At the time, Fabyan also employed a scholar named Elizabeth Wells Gallup, who was trying to prove that Sir Francis Bacon had actually written Shakespeare’s plays. Gallup needed a research assistant. Elizebeth was taken to Riverbank for an interview, and a few days later, she was hired.

At Riverbank, Elizebeth worked on a cipher that Gallup claimed was hidden in Shakespeare’s sonnets and supposedly proved Bacon's authorship. Riverbank also employed the Russian-born William Friedman, a Cornell-educated geneticist, to work on wheat, although he became increasingly drawn to the Shakespeare project. William and Elizebeth fell in love and were married in May 1917, one month after the U.S. entered World War I.

Riverbank was one of the first institutes to focus on cryptology, and in the early days of the war, the War Department relied upon Riverbank almost exclusively. "So little was known in this country of codes and ciphers when the United States entered World War I, that we ourselves had to be the learners, the workers and the teachers all at one and the same time," Elizebeth wrote in her memoir.

But the Friedmans sometimes worked for other governments, too. After a recommendation from the U.S. Department of Justice, Scotland Yard brought them a trunk full of mysterious messages the British suspected were being used to facilitate insurrection in India, which was then a British colony. By cracking the codes, written in blocks of numbers, the Friedmans exposed the Hindu-German Conspiracy—in which Hindu activists in the U.S. were shipping weapons to India with German assistance. The resulting trial was one of the largest and most expensive in U.S. history at that time, and it ended sensationally when a gunman opened fire in the courtroom, killing one of the defendants before being killed by a U.S. Marshal. Unaware of the Friedmans' codebreaking work, he apparently believed the defendant had snitched.

The war ended in 1918, but Elizebeth and William continued their work for the military, and in 1921, they moved to Washington, D.C. to focus on military contract work full-time. Elizebeth loved the change of scenery, going from the rural countryside to the city—she recalled going to the theater several times a week when she first arrived in D.C.

After a period spent working for the Navy, she left the paid workforce for a few years to start raising her children, Barbara and John. But in 1925, the Coast Guard came calling, asking for her help on Prohibition-related cases. Soon she was cracking encrypted radio messages used by international liquor-smugglers who hid booze in shipments of jewelry, perfume, and even pinto beans.

Elizebeth proved to be a pivotal asset to the Coast Guard during Prohibition. She was the star witness in a 1933 trial following the bust of a million-dollar bootleg rum operation in the Gulf of Mexico and the West Coast. When asked in court to prove how “MJFAK ZYWKB QATYT JSL QATS QXYGX OGTB" could be decoded to "anchored in harbor where and when are you sending fuel?"—just one of perhaps thousands of coded messages that formed key evidence in the trial—Elizebeth asked the judge to find her a chalkboard. She proceeded to give the court a lecture on simple cipher charts, mono-alphabetic ciphers, and polysyllabic ciphers, then reviewed how, over the course of two years, she and her team painstakingly intercepted and deciphered the radio broadcasts of four illicit distilleries in New Orleans, explaining what each transmission meant. Special Assistant to the Attorney General Colonel Amos W. Woodcock later wrote that Elizebeth's obvious proficiency "made an unusual impression."

Just a year later, Elizebeth again proved invaluable to the Coast Guard in the "I’m Alone" case, in which a ship flying a Canadian flag was sunk by the Coast Guard after refusing to acknowledge a "heave to and be searched" signal. After Canada filed a lawsuit against the U.S. for $380,000, including damages for the ship, its cargo (which included liquor), and personnel losses, Elizebeth came to the rescue: She was able to solve 23 separate encoded messages from the ship that proved the I’m Alone was actually owned by American bootleggers, despite its Canadian decoy flag. The main charges against the U.S. were dismissed, and the Canadian government was so impressed with Elizebeth’s work that it asked the U.S. for her help in catching a ring of Chinese opium smugglers. Her testimony later led to five convictions.

Elizebeth and William weren’t just code-breakers by day. Their personal fascination with cryptology permeated their whole lives, in work and in play, and built a unique bond between them. The pair used ciphers in family gatherings with their children, and developed various codes to communicate with one another as well throughout their long relationship. They were even known to host dinner parties where the menus were encoded—in order to proceed to the next course, their guests would have to solve the puzzles.

With the start of WWII, Elizebeth began working for the Coordinator of Information, an intelligence service that served as the forerunner to the Office of Strategic Services (OSS), the predecessor of the CIA. While William won huge acclaim for leading the team that figured out Japan’s Purple Encryption Machine—a discovery that gave the U.S. government access to diplomatic communications prior to the bombing of Pearl Harbor—Elizebeth’s successes were less publicized. In fact, researchers have described hitting a "brick wall" when trying to find more details of her wartime activities. But according to Jason Fagone, author of the recent biography The Woman Who Smashed Codes, Elizebeth spent the war as a Nazi spy hunter for the FBI, breaking German codes and working closely with British intelligence to bust Axis spy rings. J. Edgar Hoover wrote her out of the story once the war had ended, classifying her files as top-secret and taking the credit for himself.

One piece of Elizebeth's work for the FBI is slightly better-known, however: Her code-cracking expertise was key in solving the "Doll Woman Case" of 1944, wherein Velvalee Dickinson, an antique doll dealer based in New York City, was convicted of spying on behalf of the Japanese government. Elizebeth's work helped prove that letters Dickinson had written, though seemingly about the condition of antique dolls, actually described the positions of U.S. ships and other war-related matters and were intended for the hands of Axis officials. As Fagone notes, although newspapers of the day wrote breathlessly about Dickinson as "the War's No. 1 woman spy" and how her codes were cracked by "FBI cryptographers," Elizebeth was never mentioned.

Elizebeth retired in 1946, a year after World War II ended, and William did the same the following year. In 1957, after many years of research, they finally published their masterwork on the bard, The Shakespearean Ciphers Examined, which won awards from several Shakespeare research facilities. In contradiction to Gallup's theories, the Friedmans denied that Francis Bacon had written any works known as Shakespeare’s, and they even buried a cheeky message to that effect on one of the pages—an italicized phrase that when deciphered reads: "I did not write the plays. F. Bacon."

After William’s death in 1969, Elizebeth dedicated large amounts of her time to compiling and documenting her husband’s work in cryptology, rather than celebrating her own extraordinary achievements in the field. The fruits of her effort would eventually become part of the George C. Marshall Research Library, named after the WWII-era Chief of Staff of the U.S. Army.

Elizebeth herself died on Halloween 1980 and was interred with her husband at Arlington National Cemetery. Inscribed on their double gravestone is a quote, not by William Shakespeare, but commonly attributed to Francis Bacon: "KNOWLEDGE IS POWER." It too is a cipher—when decrypted, it reads "WFF," William Friedman's initials.

It was December 15, 1890 and Sitting Bull was dead. The Indian police who had shot and killed him earlier that day were tearing through his cabins when they found two of the chief's wives and several other women hiding his son under a mattress, a portrait of the dead Hunkpapa Lakota leader hanging on the wall. Though they had been ordered not to touch anything, one of the policemen tore the painting down, using his rifle to smash the frame and his fist to punch a hole in the canvas. Lieutenant Matthew F. Steele, a cavalry member among those sent to assist the policemen, wrestled the painting—done, he later recalled, by a "Mrs. Weldon, a woman from the East"—away before it could be destroyed completely. Steele bought the painting from Sitting Bull's wives for $2 and kept it for six decades, donating it to the State Historical Society of North Dakota in 1953.

But who was the “Mrs. Weldon” who had journeyed all the way from the East to the Standing Rock Reservation to paint it? As in Steele's recollection, she is often a footnote to history—treated like a passing phantom when mentioned at all. Yet Caroline Weldon is worth remembering as an activist who set out alone to try and help Sitting Bull and his people. While her story as a white woman attempting to guide indigenous affairs is not uncomplicated, what she did was rare both in terms of 19th century activism and for a single woman in the Victorian era. Her courage is reflected in the nickname the Sioux gave her: “Woman Walking Ahead."

The woman who would become Caroline Weldon was born Susanna Karolina Faesch in a suburb of Basel, Switzerland, in 1844. Her parents divorced when she was almost 5 years old, and she arrived in the United States with her mother in the 1850s. She grew up in Brooklyn, where she eventually married a fellow Swiss named Claudius Bernhard Schlatter. It was an unhappy marriage—at one point she left him for another man—and they divorced in 1883.

As she "struggled to endure her loveless marriage," Eileen Pollack writes in her book Woman Walking Ahead, the budding activist immersed herself in reading about the news of the West, particularly Sitting Bull’s leadership of the Sioux in Standing Rock. After her divorce, she joined the National Indian Defense Association (NIDA), formed by activist Dr. Thomas Bland with his wife Cora in response to the controversial Dawes Act. The act, passed in 1887, broke up indigenous land into individual allotments—often seen as a key step in the federal government's forced assimilation of Native Americans. It was sometime in the 1880s, according to researcher Daniel Guggisberg, that she also invented a new name for herself: Caroline Weldon. By then, she'd also had a son, named Christie, out of wedlock.

In 1889, accompanied only by Christie, Weldon left Brooklyn and went west to offer her support of Sitting Bull’s opposition to the Dawes Act in person. Although Sitting Bull had been well-known as a commander at the 1876 Battle of the Little Bighorn, by the 1880s, aside from a stint with Buffalo Bill's Wild West show, his life was confined to the Standing Rock reservation. When Weldon arrived in June of 1889, he was suffering from a near-fatal bout of pneumonia.

For several months after arriving at Standing Rock, Weldon acted as Sitting Bull’s secretary. She also painted four portraits of him, and offered financial support to him and his family, drawing on a small inheritance from her mother. Weldon would later describe her impression of Sitting Bull: "As a friend […] sincere and true, as a patriot devoted and incorruptible. As a husband and father, affectionate and considerate. As a host, courteous and hospitable to the last degree.”

And while Sitting Bull seems to have appreciated her actions, not everyone did. Indian Agent James McLaughlin—one of the individuals authorized to interact with Native American tribes on behalf of the U.S. government, and who would order Sitting Bull’s fatal arrest—openly detested Weldon for her meddling. The press was also unkind, calling her “Sitting Bull’s white squaw.” One 1889 headline in the Bismarck Weekly Tribune crowed: "A New Jersey Widow Falls Victim to Sitting Bull's Charms.”

But any cooperation between Weldon and Sitting Bull would be interrupted by the dawn of the Ghost Dance in the Dakotas. The movement was sparked by a Paiute man named Wovoka, who prophesied in 1889 that the circular dance would help return the dead to the land of the living, where they would fight and force the white people off the land they'd stolen before uniting the indigenous people in peace. At a time when the Dawes Act was dividing ancestral land, and after decades of federal genocide, the Ghost Dance quickly became a phenomenon.

Weldon correctly assessed that Sitting Bull’s participation in the Ghost Dance would be used to arrest or kill him; she incorrectly perceived the spread of the dance as a Mormon plot. (The Mormons had been active in attempting to convert indigenous people as they moved into western land in the 1800s.) The growing tension around Weldon’s advocacy against the dance eventually led to her expulsion from the reservation.

She pled in a letter addressed to "My Dakotas": "Your dead friends will not come back to you. Save your money and take care of the living.” According to Ian Frazier in his 1989 book Great Plains, Sitting Bull tried proposing marriage to her—an attempt she rebuffed. She "finally left Sitting Bull's camp in disgust," and Sitting Bull drove her to the nearby town of Cannonball in his wagon.

The final years of Weldon's life were bleak. Only a month before Sitting Bull was killed on December 15, 1890, her son died of an infection. After spending some time in Kansas City, she came home to Brooklyn, falling into obscurity as the years went on. One night in 1921, a candle caught her apartment on fire, and she died on March 15 from her burns. Today, she’s buried in Brooklyn’s Green-Wood Cemetery, near an obelisk marked Valentiny, her stepfather’s name.

Christine Granville, World War II Special Agent

The Allies’ success in World War II owes a great debt to the women who outfoxed, out-shot, and outran their male counterparts across the globe. Perhaps most intriguing of these women, although little-known today, is Christine Granville, the Polish-born daughter of a ne’er-do-well count and a Jewish mother, whose real-life romantic entanglements, fearless sorties, and close escapes are enough for reams of dramatic stories.

Born Krystyna Skarbek in Warsaw in 1908 to an aristocratic, but broke, family of Polish nobility on her father’s side and a successful, but socially limited, Jewish banking family on her mother’s side, Christine, as she later came to be known, seemed destined to be able to handle whatever situation life threw at her. Likeable, beautiful, and driven by a strong sense of fun, she used her resources before the war to become an expert equestrian, a top-notch skier, and even a national beauty queen.

But her ancestry meant she would never quite fit in. According to Clare Mulley, the author of a biography about Granville called The Spy Who Loved, it would be this outsider foundation that later drove Granville to accomplish great things. As Mulley explained to Mental Floss, “although beautiful and well-connected, her mother had been born Jewish, and Christine was never fully accepted in the higher echelons of Polish society.”

The Nazi invasion of Poland in the fall of 1939 was, of course, a game-changer. Trapped in London with her diplomat husband, Jerzy Giżycki, and desperate to help the war effort in any way she could, Granville found a contact in the British Secret Intelligence Service (SIS) and pressed herself into service. She became Britain's first—and longest-serving—female special agent during World War II. Her facility for languages, her intelligence, and her calm under pressure all proved to be great assets in her espionage work, as she made her way in and out of Nazi-held territories. Even her long-time interest in skiing proved useful, allowing her to sneak into war-torn Poland by traversing the mountains just ahead of enemy soldiers.

Along the way there would be close calls, romantic intrigues, and triumphs that would become the stuff of spy novels. These included her escape from a Gestapo interrogation by faking a case of tuberculosis: Spies had been informed that Germans were terrified of catching the contagious disease, so Granville simply manufactured some symptoms during her detention by biting her tongue until it bled and then “coughing up” blood in the presence of her captors. Afraid to have someone in her condition in their custody, she was promptly let go and returned to her spying duties.

According to Mulley, Christine had one particularly impressive feat among her many accomplishments. “Christine became legendary within SOE [Britain's Special Operations Executive] for her single-handed rescue of three fellow agents from Gestapo prison, just hours before they were due to be shot in July 1944. One of the men was her lover, Francis Cammaerts, the leader of SOE in the south west of France, who went on to help coordinate French resistance support for the Allied troops arriving to liberate occupied France from the south.”

Active in no less than three theaters of war, Granville survived six years of dangerous fieldwork in an occupation where the average life span was six weeks. As a reward, she was decorated by both Britain and France. Sadly, however, her story ends with a twist that would put even writers like John le Carré to shame. She was killed by a man whose romantic overtures she spurned. As Mulley explains, “Christine met her untimely end in a south London hotel in 1952. Her murderer claimed that ‘to kill is the final possession.’ He was wrong. Nobody possessed Christine, not her father, not either of her husbands, and none of her many lovers. If anything, she was possessed by her drive for freedom.”

Her legacy, even if little-known and under-sung, endures. Thought to have inspired at least two of James Bond author Ian Fleming’s characters (the author never met her, but he may have heard of her exploits through his own MI5 contacts), Granville remains a figure who deserves further exploration. Mulley argues that she deserves more than the sensationalist treatment of paperbacks and action movies, adding that “her legacy lies in her inspirational example of a Pole fighting for Britain and her countries’ allies, and as a woman serving so effectively behind enemy lines. All too often women in the resistance are presented in romantic terms, as brave and beautiful. Christine had both these qualities, but she also made a hugely significant contribution to the Allied war effort."
