With the establishment of the OSS Morale Operations (MO) branch, psychological warfare redefined America’s intelligence and communications.  MO employees worked with “black” propaganda—disinformation that is deniable by (and not traceable to) its source.  This technique became an effective tool for influencing enemy opinions and perceptions.

Marlene Dietrich (1901-1992)

  • Born in Berlin; became an American citizen in 1939.
  • Singer, actress, and OSS volunteer.
  • Entertained frontline Allied troops throughout World War II, often within firing range of enemy units.
  • Recorded popular songs such as "Lili Marlene," "I Couldn’t Sleep a Wink Last Night," "Miss Otis Regrets," "Taking a Chance on Love," "Time in My Hands," "Annie Doesn’t Live Here Anymore," "Mean to Me," and "The Surrey with the Fringe on Top" in German; OSS then broadcast the recordings to combat-weary German troops as part of a psychological warfare operation designed to lower their morale and fighting effectiveness.
  • OSS director William Donovan extended his gratitude for Dietrich’s help:
    I am personally deeply grateful to you for your generosity in making these recordings for us
