Edith “Jackie” Ronne overwintered on the Antarctic continent in 1947-48, at a time when Antarctic expeditions were planned, staffed and led almost exclusively by men. Women were generally regarded as unsuitable for the physical and psychological demands of polar life. Ronne challenged that assumption. Her pioneering began not with a plan to make history, but with a refusal to accept the limits placed on women. She spent 15 months at a small station on Stonington Island with 21 men and one other woman, Jennie Darlington. No women had overwintered on the Antarctic continent before that season.
Edith “Jackie” Ronne was born on 13 October 1919. She graduated in history from George Washington University. Her work included time at the National Geographic Society and the U.S. State Department. Finn Ronne, her husband and a polar explorer, led the Ronne Antarctic Research Expedition (1947-48). She went with the expedition as far as South America at first. He persuaded her to continue south. She agreed only if another woman came too. Jennie Darlington, the wife of the expedition's pilot, joined them.
Ronne served as recorder and historian
Her role went beyond symbolism. At Stonington Island, Ronne served as recorder and historian. She kept the daily record, wrote dispatches for the North American Newspaper Alliance, and helped with scientific work that included tidal and seismographic observations. Finn Ronne later used her records as an important basis for his account of the expedition. Accounts written at the time often presented Ronne mainly through her husband. The expedition record shows an active member who documented, observed, communicated and contributed to the science in one of the world's most challenging environments. That record is also a reminder of how easily women's contributions can disappear from the historical record.
Ronne kept returning to Antarctica after 1948
Ronne kept returning to Antarctica after the expedition ended. She made many trips back, including a flight to the South Pole in 1971 and a return to the old base at Stonington Island in 1995. From 1978 to 1981, she was president of the Society of Woman Geographers. The Ronne Ice Shelf, among the largest ice shelves in Antarctica, carries her name.
The first overwinter did not open the field immediately
In 1947, the two women crossed a line many contemporaries treated as fixed: Antarctica was for men. Station histories record that women scientists did not overwinter in Antarctica until the 1970s. Ronne's story is part of a longer journey toward an inclusive Antarctic community where gender should not determine who explores, researches, leads or shapes understanding of the continent. Ronne helped make the Antarctic scientific community a place where women could belong.
Her importance is not only that she was first. It is about who is counted as a contributor, whose work enters scientific history, and who gets to take part in exploration. The date to mark is 13 October, her birthday. The useful act is to check whose work an expedition record names, and to ask whether the next Antarctic season's science plan credits the people who do the work.
