Douglas Mawson was born in Yorkshire on the 5th of May 1882, and came to Australia as a boy. In 1911 he was the leader of the first Australasian Expedition to Antarctica. When he returned to Adelaide, he was knighted for his contribution to our scientific understanding of Antarctica. He was to become the most famous Australian Antarctic explorer and geologist. In 1929 and 1931 Mawson headed two more voyages to the Antarctic.He died at the age of 76 on the 14th of October 1958. The Australasian Antarctic Expedition is today regarded as one of the greatest polar scientific expeditions of all times because of the detailed observations in magnetism, geology, biology and meteorology that were made.
John Tebutt was born at Windsor on the 25th May 1834. From the young age of eighteen, he slowly rose among the academic astronomical community, whose personal stature was considered by many as their equal, and certainly as even more capable, than nearly all his fellow Australian and international astronomers. In 1864 he built, with his own hands, a small observatory.He died on the 29th November 1916 at the age of eighty-two, having produced more than 370 scientific papers.
