Freuchen married three times: first, in 1911, to an Inuit woman named Navarana Mequpaluk (d. 1921), who died in the Spanish Flu epidemic after bearing two children (a boy named Mequsaq and a girl named Pipaluk); next, in 1924, to Magdalene Vang Lauridsen (the marriage was dissolved in 1944); and lastly, in 1945, to Dagmar Cohn.
He was also employed by the movie industry as a consultant and scriptwriter, specializing in Arctic-related scripts. Most notably MGM's Oscar winning "Eskimo/Mala The Magnificent" starring Ray Mala. In 1956 he won $64,000 on an American TV quiz-show on the subject "The Seven Seas".
During World War II, Freuchen was actively involved with the Danish resistance movement against the Germans, despite having lost a leg some years previously. He was imprisoned for a time by the Germans.
After his death, his ashes were scattered on a mountain near Thule.
