Peary's adventurous Arctic childhood provided fodder for her writing. She published five books for children:
Little Tooktoo: The Story of Santa Claus’ Youngest Reindeer (1930),
Muskox: Little Tooktoo’s Friend (1931),
The Red Caboose: With Peary in the Arctic (1932),
Snow Baby (1935, an autobiography for children), and
Ootah and His Puppy (1942). For adults, she published
The Snowbaby’s Own Story (1934, her memoirs) and
Discoverer of The North Pole: The Story of Robert E. Peary (1959). Throughout her life, she championed her father's legacy, convinced that he was the first white explorer to reach the North Pole. She was instrumental in raising monuments to her father's memory at
Arlington National Cemetery,
Cape York in Greenland, and Jockey Cap Mountain in
Fryeburg, Maine. Peary received
King Christian X’s Liberty Medal for serving on the Danish-American commission that helped manage the affairs of Greenland during World War II. She served as president of the
Society of Woman Geographers, in which she stayed active for 50 years. She received an honorary Master of Arts degree from
Bowdoin College (her father's alma mater) in 1949 and the
Henry G. Bryant Medal from the
Geographical Society of Philadelphia in 1954. She gifted her father's papers to the
National Archives. She and her brother donated the Pearys' private island,
Eagle Island in
Casco Bay, to the State of Maine in 1967. == Personal life ==
