On her arrival, the United States government placed her under security surveillance by the FBI. In March 1941, she was detained for several days by US immigration authorities. She made up to Major Lemuel B. Schofield, the Director of the US Immigration and Naturalization Service in Washington, DC. He put her up in the Raleigh Hotel, where he also lived, and the two carried on an affair that lasted several months. She then lived with her mother and son in Alexandria, Virginia. In October 1941, the FBI prepared a memo describing her as "extremely intelligent, dangerous and clever," and claiming that as a spy, she was "worse than ten thousand men". Summarizing what was known about her, it recommended that her deportation not be further delayed and noted that the British and the French, in addition to the United States intelligence community, suspected her of being a spy for Germany. She continued to stay in the US. After the Japanese attack on Pearl Harbor and the formal entry of the US into World War II, the FBI arrested Princess Stephanie, interning her at a facility in Philadelphia and later at a Texas camp for enemy aliens. On January 10, 1942, the enemy alien hearing board in Philadelphia recommended to Attorney General Biddle that she be interned for the duration of the war, based on an interview the previous month. She was interviewed by personnel of the new Office of Strategic Services (OSS). She was paroled in May 1945. It was not until 2005 that British intelligence MI6 and the US FBI declassified and released some of the documents from those years and that they became available to researchers. American files show that during her interrogation by the OSS, she provided insights into the character of Hitler, which were used by Henry A. Murray, Director of the Harvard Psychological Clinic, and psychoanalyst Dr. Walter C. Langer, in preparing the 1943 OSS report entitled Analysis of the Personality of Adolph Hitler. Later life In the postwar era, Princess Stephanie returned to Germany, where she established new, influential connections. She worked with media executives such as Henri Nannen of Stern news magazine and Axel Springer, the owner of the Axel Springer AG publishing company. For the latter, she secured interviews with US Presidents John F. Kennedy and Lyndon B. Johnson. She died in Geneva, Switzerland, in 1972 and is buried there. See also
