Gertrude Kahn, also known as Mrs. Ray Kahn, was an American who allegedly had a covert relationship with Soviet intelligence during World War II. In a Venona transcript from Moscow, the Moscow Center suggested Mrs. Kahn be used for foreign intelligence work. The New York Rezidentura responded that it may not be wise, and that she was best suited for a "passive" role. Kahn's code name in Soviet intelligence and in the Venona decrypts is "Dinah."
