The original crew of the Maud expedition comprised nine men with extensive experience from previous expeditions and scientific work. As early as 1919, however, two men, Peter Tessem and Paul Knutsen, left the expedition. They were to bring the expedition’s scientific material and mail back to Norway, but died on the way to the telegraph station at Dikson, Siberia. Ahead of the expedition’s second phase (1922–25), several of the crew were replaced and experienced pilots and scientific assistants were brought on board. The original crew was composed only of men from Norway and Sweden, but several local and indigenous people, such as Gennadiy Olonkin and Kakot, also became key members of the expedition.
