When geographers recommended the exploration of the Antarctic regions at the close of the nineteenth century, Germany and Britain were eager to do their best. The promoters of Antarctic research, such as Georg von Neumayer (1826–1909) in Hamburg and Clements Markham (1830–1916) in London, could finally raise enough money to build national flagships for science. Despite unfavourable political circumstances, due to political rivalry between Germany and Great Britain, the leaders of the expeditions — Erich von Drygalski (1865–1949) and Robert Falcon Scott (1868–1912) — agreed to a scientific collaboration with regard to meteorological and magnetic measurements in Antarctica during 1901–1903, which later was extended until 1904. This paper reveals that favourable circumstances such as the International Geographical Congresses in London (1895) and Berlin (1899) played a major role in increasing scientific interest in and public support of Antarctic research, ultimately leading to international collaboration.
