 However, Roald Amundsen, conqueror of the South Pole in 1911, acknowledged that Borchgrevink's expedition had removed the greatest obstacles to Antarctic travel, and had opened the way for all the expeditions that followed.Born in Oslo in 1864 to a Norwegian father and an English mother, Carsten Borchgrevink emigrated to Australia in 1888, where he worked as a land surveyor in the interior before accepting a provincial schoolteaching appointment in New South Wales.Having a taste for adventure, in 1894 he joined a commercial whaling expedition, led by Henryk Bull, which penetrated Antarctic waters and reached Cape Adare, the western portal to the Ross Sea.
