Throughout history, some of the most dangerous intelligence operatives were women who operated in plain sight, often underestimated by their adversaries. These ten female spies pulled off audacious missions, turned the tide of wars, and exposed secrets that shook governments—yet their stories remain largely forgotten. Get ready to discover the women who rewrote the rules of espionage.

#1: Mata Hari—The Original Double Agent

You’ve probably heard whispers of Mata Hari, but her story is even more scandalous than legend suggests. Born Margaretha Geertruida Zelle, she seduced military officers across Europe while selling secrets to multiple nations during World War I. Her espionage career ended dramatically when she was executed by firing squad in 1917—making her history’s most infamous spy.

#2: Christine Granville—The First SOE Agent

Before James Bond, there was Christine Granville, who became Britain’s first female special operations agent during World War II. You might not realize she was fluent in multiple languages and survived Nazi-occupied Poland by sheer wit and cunning. She later saved the life of a British officer by bluffing her way past German soldiers with a fake bomb—and lived to tell about it.

#3: Josephine Baker—The Dancer Who Spied for France

You know Josephine Baker as an iconic jazz performer, but during World War II she was one of France’s most valuable intelligence assets. The beloved entertainer used her fame and access to high-society gatherings to gather classified information, writing secret messages on her sheet music in invisible ink. She risked everything for the French Resistance while never missing a performance.

#5: Noor Inayat Khan—The Princess Turned Wireless Operator

Noor Inayat Khan was a British-Indian princess who became a Special Operations Executive wireless operator in Nazi-occupied Paris. You might be surprised to learn she was the last British SOE agent remaining in the city after her colleagues were arrested. She continued transmitting intelligence from increasingly dangerous hiding spots until her capture, ultimately dying in a concentration camp in 1944.

#6: Marthe Cohn—The French-Jewish Nazi Impersonator

Marthe Cohn pulled off one of espionage’s most audacious stunts: she impersonated a Nazi officer to gather intelligence for the French Army during World War II. You have to admire the sheer nerve it took to walk into German military camps in disguise while being hunted as a Jewish woman. She survived the war and lived to be over 100 years old, writing a memoir about her incredible double life.

#7: Sorge Richard’s Network—Agnes Smedley’s Secret Role

Agnes Smedley was an American journalist who became part of one of the Soviet Union’s most effective spy rings in 1930s China. You might not know that while reporting on the Chinese-Japanese conflict, she was simultaneously gathering military intelligence for Moscow. Her network included the famous spy Richard Sorge, and together they provided Stalin with crucial information about Japanese military movements.

#8: Daphne Park—The Cold War Veteran

Daphne Park served as a British intelligence officer for over four decades, rising to become Deputy Chief of MI6—a position almost unheard of for women at the time. You might be amazed to learn she operated undercover throughout the Cold War, including dangerous postings in Moscow and other Soviet-controlled territories. Her intelligence work helped shape the West’s understanding of Soviet intentions during the most tense era of the twentieth century.

#9: Nancy Wake—The Gestapo’s Most Wanted

Nancy Wake was an Australian SOE operative who became the Gestapo’s most wanted person during World War II with a bounty on her head. You’d be fascinated by her fearlessness—she led thousands of French Resistance fighters, coordinated parachute drops, and escaped the Nazis multiple times through sheer determination. After the war, she received numerous medals and became one of the most decorated female operatives in history.

#10: Ashraf Marwan—Hosni Mubarak’s Spy Who Changed History

Ashraf Marwan was technically a male spy, but his intelligence network relied heavily on female operatives who infiltrated Arab governments during the Cold War and Middle Eastern conflicts. You might not realize how critical female agents were to his operation’s success, particularly in gathering political intelligence from diplomats and government officials. His network’s intelligence became so valuable that multiple world powers competed to protect him.

These women proved that espionage has no gender—and that history’s most dangerous intelligence operatives are often the ones no one sees coming. Their legacies remind us that some of the twentieth century’s pivotal moments were shaped by brilliant women working in the shadows.
