Who dated 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. Secret U.S. investigations uncovered no such evidence, and her past did not harm her professional life or social standing in the United States. She was a motion picture writer for Metro-Goldwyn-Mayer in 1945 and a Hollywood gossip columnist, and from the late 1940s until her death, she was the wife of wealthy cowboy actor and military officer Tim McCoy.
