Arctic exploration In 1929, Demme graduated and went to work at the
Arctic and Antarctic Research Institute which was founded in 1930. Because of her extensive experience and research background, Demme was selected to participate in an expedition on the icebreaker
George Sedov, which planned to winter on
Franz Josef Land. Ivanov was sent to manage the polar station in Tikhaya Bay on
Hooker Island, with the 11 scientists being led by
Otto Schmidt. Demme was the only woman among them and international news coverage at the time claimed she was the first woman to have explored the Arctic. Her work involved both geographical and biological studies, and the crew wintered for two years on the island. When not making expeditions to study the wildlife and plants, Demme assisted the
hydrologist in his measurements. During the expedition, Demme and Ivanov divorced, and she married another of the scientists. When they returned from the trip, that marriage ended, and she married Gabriel Ignatievich Ioylev, a radio operator. In 1932, she led a team of three men, including a hunter, meteorologist, and her husband, Ioylev, the radio operator, to winter in the
Kamenev Islands, and newspapers reported that she had been the first woman to lead a polar expedition. The group sailed on the
Roussanov, arriving on 14 August and settling into the cabin which had a large bedroom with bunk beds and a library, as well as a large dining table, where they listened to concerts and news broadcasts each evening during dinner. She was made governor of the
archipelago and had the authority to direct commerce, immigration, and other affairs of state. The group was to remain one winter and evaluate the commercial possibilities for the
flora and
fauna of the islands. They gathered geological and botanical samples, studied the various animals on their expeditions, and mapped the western part of Severnaya Zemlya. As icebreakers were unable to reach, them the team ended up spending a second year in the Arctic. Various mishaps befell the crew, including one when, while out hunting, the men mistook Demme for a polar bear and she began to sing an aria from
La traviata so they would know she was not their prey. In September 1934, Alexander Alexiev, a government pilot, flew from Siberia and was able to extract Demme and her crew, as well as Boris Lavrov and his pilot, who had been on an expedition of the
Lena River before their plane crashed and they walked 185 miles to reach the Kamenev station.
Academic career Returning to Leningrad, Demme began post-graduate studies at the Arctic and Antarctic Research Institute, where she also taught courses in biology and zoology. She was interested in researching the commercial collective farming potential of animals of the north and for several seasons studied black foxes. Because she could not get the institute to finance her expeditions, Demme chartered small fishing boats to take her to remote Arctic huts so that she could carry out her research. Beginning around 1940, she utilized methods established in Iceland to create experimental eider farms in
Novaya Zemlya and on
Vaygach Island. By setting up nesting shelters and killing the predators of the birds, locals under her leadership were able to collect of
eiderdown over a five-year period. Demme completed her dissertation,
Гнездовые колонии гаги обыкновенной на Новой Земле и организация гагачьего хозяйства (
Nesting Colonies of the Common Eider on Novaya Zemlya and the Organization of the Eiderdown Economy) in 1946, earning her
Candidate's Degree in biology. Demme was made an associate professor in 1949, but did not like the confinement of the classroom. She continued to hire small commercial vessels to allow her to study wildlife in the Arctic into the 1950s. In 1949, she conducted research in the
Kandalaksha Nature Reserve on the
White Sea, extending her work on eiders. At the reserve, she attempted to develop domesticated hatcheries, which she had unsuccessfully tried to establish in Novaya Zemlya. Though successful, the group of chicks she brought back to Leningrad at the end of the season failed to thrive and all died. In 1952, Demme made her last trip to the Arctic, working in the northern parts of the
Gulf of Ob in Siberia, and focusing on raising animals there. She did not return to the Kandalaksha Reserve, though others continued to study eider chicks there. Though she was not involved, her experimental eiderdown farms operated until 1954, when they were closed and the native inhabitants of Novaya Zemlya were removed in preparation for nuclear tests. In 1959, she retired and wrote her autobiography. She was allowed to buy a summer house on the Black Sea coast and chose a place between
Sochi and
Tuapse near Volkonskaya, where she built a home and an extensive garden, which had various kinds of flowers and trees. An accomplished musician and skilled artist, she also created paintings. ==Death and legacy==
