Marie Marvingt (1875-1963) set the world's first women's aviation records, won the only gold medal for outstanding performance in all sports, invented the airplane ambulance, was the first female bomber pilot in history, fought in World War I disguised as a man, took part in the Resistance of World War II, was the first to survive crossing the English Channel in a balloon, worked all her life as a journalist, spent years in North Africa and invented metal skis. Her life story was so unusually rich in exploits and accomplishments that some dismissed it as a hoax. This biography explores the life of "the most incredible woman since Joan of Arc" and investigates the reasons she has been forgotten. Known as the "fiancee of danger," she was the model for the silent film series The Perils of Pauline.
