Inga Arvad
Inga Marie Arvad Petersen (6 October 1913 – 12 December 1973) was a Danish-American journalist who was a guest of Adolf Hitler at the 1936 Summer Olympics and also had a romantic relationship with John F. Kennedy in 1941 and 1942. The juxtaposition of these facts led to suspicions during World War II that she was a Nazi spy.
