Scientist of the day - Douglas Mawson

Sir Douglas Mawson was an Australian explorer, geologist and academic. An alumnus of the University of Sydney, Mawson developed interest in expeditions early in his life. As a lecturer at the University of Adelaide, he became interested in rocks left by melting glaciers and therefore, when he got the chance to join Nimrod Expedition to Antarctica he readily agreed. Soon after returning, he organized his own Australian Antarctic Expedition. The data collected by the expedition were later edited and published in twenty-two volumes. However, the expedition also highlighted his survival capacity. After the death of his two companions he traveled for almost a month all by himself and reached the base camp only to find that the ship had left just few hours before his arrival. Much later, he led another expedition to the Antarctic. It enabled Australia to claim some 2,500,000 square miles of the continent. 

Childhood & Early Years
Douglas Mawson was born on May 5, 1882, in Shipley, West Yorkshire, England. His father, Robert Mawson, was a cloth merchant from a farming background. His mother’s name was Margaret Ann née Moore.

Major Works
  • Mawson is best known for his expeditions to Antarctica. They enabled Australia to claim some 2,500,000 square miles of that continent. These expeditions also collected huge amount of scientific data, which helped to carry on further investigation.
  • Mawson also made major contributions to Australian geology. In later years, he worked on the 'Adelaide System' of Precambrian rocks in the Flinders Ranges and identified its two groups. His findings have been documented in his report ‘Geological investigations in the Broken Hill area’.
