Famed chef Julia Child shared a secret with Supreme Court Justice Arthur Goldberg and Chicago White Sox catcher Moe Berg at a time when the Nazis threatened the world.

They served in an international spy ring managed by the Office of Strategic Services, an early version of the CIA created in World War II by President Franklin Roosevelt.

The full secret comes out Thursday, all of the names and previously classified files identifying nearly 24,000 spies who formed the first centralized intelligence effort by the United States. The National Archives, which this week released a list of the names found in the records, will make available for the first time all 750,000 pages identifying the vast spy network of military and civilian operatives.
