William Speirs Bruce (1 August 1867 – 28 October 1921) was a Scottish naturalist, polar scientist and oceanographer who organized and led the Scottish National Antarctic Expedition (SNAE, 1902–04) to the South Orkney Islands and the Weddell Sea. Among other achievements, the expedition established the first permanent weather station in Antarctica. Bruce later founded the Scottish Oceanographical Laboratory in Edinburgh, but his plans for a transcontinental Antarctic march via the South Pole were abandoned because of lack of public and financial support.
