In 1941, at the onset of World War II, Julia moved to Washington, D.C., where she volunteered as a research assistant for the Office of Strategic Services (OSS), a newly formed government intelligence agency. In her position, Julia played a key role in the communication of top-secret documents between U.S. government officials and their intelligence officers. She and her colleagues were sent on assignments around the world, holding posts in Washington, D.C., Kumming, China; and Colombo, Sri Lanka. In 1945, while in Sri Lanka, Child began a relationship with fellow OSS employee Paul Child. In September of 1946, following the end of World War II, Julia and Paul returned to America and were married.
In 1948, when Paul was reassigned to the U.S. Information Service at the American Embassy in Paris, the Childs moved to France. While there, Julia developed a penchant for French cuisine and attended the world-famous Cordon Bleu cooking school. Following her six-month training—which included private lessons with master chef Max Bugnard—Julia banded with fellow Cordon Bleu students Simone Beck and Louisette Bertholle to form the cooking school L’Ecole de Trois Gourmandes (The School of the Three Gourmands).
