Sir Douglas Mawson OBE FRS FAA (5 May 1882 – 14 October 1958) was an Australian geologist, Antarctic explorer and academic. Along with Roald Amundsen, Robert Falcon Scott, and Ernest Shackleton, Mawson was a key expedition leader during the Heroic Age of Antarctic Exploration.
Mawson was born on 5 May 1882 to Robert Ellis Mawson and Margaret Ann Mawson (née Moore). He was born in Shipley, West Yorkshire, but was only two years old when his family immigrated to Australia and settled at Rooty Hill, now in the western suburbs of Sydney. He attended Fort Street Model School and the University of Sydney, where he graduated in 1902 with a Bachelor of Engineering.
He was appointed geologist to an expedition to the New Hebrides (now Vanuatu) in 1903; his report The Geology of the New Hebrides, was one of the first major geological works of Melanesia. Also that year he published a geological paper on Mittagong, New South Wales. His major influences in his geological career were Professor Edgeworth David and Professor Archibald Liversidge. He then became a lecturer in petrology and mineralogy at the University of Adelaide in 1905. He identified and first described the mineral Davidite.
Mawson joined Ernest Shackleton’s Nimrod Expedition (1907-09), originally intending to stay for the duration of the ship’s presence in the first summer. Instead both he and his mentor, Edgeworth David stayed an extra year. In doing so they became, in the company of Alistair Mackay, the first to climb the summit of Mount Erebus and to trek to the South Magnetic Pole, which at that time was over land.

The first day of issue is the day on which a postage stamp, postal card or stamped envelope is put on sale, within the country or territory of the stamp issuing authority. Sometimes the issue is made from a temporary or permanent foreign or overseas office. There will usually be a first day of issue postmark, frequently a pictorial cancellation, indicating the city and date where the item was first issued, and “first day of issue” is often used to refer to this postmark.A first day cover(FDC) is an envelope whereupon postage stamps have been cancelled on their first day of issue. Depending on the policy of the nation issuing the stamp, official first day postmarks may sometimes be applied to covers weeks or months after the date indicated.Unofficial first day of issue postmarks can also occur when a stamp collector purchases the stamps in question from a post office in the first day of issue city and then takes them (on that same day) to a post office in another city to have them cancelled, or when stamps are affixed to envelopes that are simply dropped into the mailstream on the first day and receive that day’s normal postmark.
