At the end of the 1940s Freuchen-Gale began to teach fashion illustration at the Art Students League, and continuing there for 20 years.

Her first husband, a Danish man named Muller, was killed during World War II while serving with the American army in the Pacific.

Beginning in 1945, they lived in New York City and maintained a second home in Noank, Connecticut on Chesbro Street, overlooking Long Island Sound.

Freuchen often travelled for his work during their marriage but is reported to have written home every day and sent a copy of each letter to the Danish Royal Library, to be opened 50 years after his death, in 2007.

Freuchen-Gale joined her husband only once in his travels, on an expedition to Iceland, during which she served native meals including pickled whale blubber and seaweed.
