Ernest Shackleton

Context: After a period of convalescence in New Zealand, Shackleton returned to England via San Francisco and New York. As the first significant person to return from the Antarctic, he found that he was in demand; in particular, the Admiralty wished to consult him about its further proposals for the rescue of Discovery. With Sir Clements Markham's blessing, he accepted a temporary post assisting the outfitting of the Terra Nova for the second Discovery relief operation, but turned down the offer to sail with her as chief officer. He also assisted in the equipping of the Argentinean corvette Uruguay, which was being fitted out for the relief of the stranded Swedish Antarctic Expedition under Nordenskiold. In search of more permanent employment, Shackleton applied for a regular commission in the Royal Navy, via the back-door route of the Supplementary List, but despite the sponsorship of Markham and of the president of the Royal Society, he was not successful. Instead, he became a journalist, working for the Royal Magazine, but he found this unsatisfactory. He was then offered, and accepted, the secretaryship of the Royal Scottish Geographical Society (RSGS), a post which he took up on 11 January 1904. On 9 April 1904 he married Emily Dorman, with whom he had three children: Raymond, Cecily, and Edward. In 1905, Shackleton became a shareholder in a speculative company that aimed to make a fortune transporting Russian troops home from the Far East. Despite his assurances to Emily that "we are practically sure of the contract", nothing came of this scheme. He also ventured into politics, unsuccessfully standing in the 1906 General Election as the Liberal Unionist Party's candidate for Dundee in opposition to Irish Home Rule. In the meantime he had taken a job with wealthy Clydeside industrialist William Beardmore (later Lord Invernairn), with a roving commission which involved interviewing prospective clients and entertaining Beardmore's business friends. Shackleton by this time was making no secret of his ambition to return to Antarctica at the head of his own expedition. Beardmore was sufficiently impressed with Shackleton to offer financial support, but other donations proved hard to come by. Nevertheless, in February 1907, Shackleton presented to the Royal Geographical Society his plans for an Antarctic expedition, the details of which, under the name British Antarctic Expedition, were published in the Royal Society's newsletter, Geographical Journal. The aim was the conquest of both the geographical South Pole and the South Magnetic Pole. Shackleton then worked hard to persuade others of his wealthy friends and acquaintances to contribute, including Sir Philip Lee Brocklehurst, who subscribed PS2,000 (2011 equivalent PS157,000) to secure a place on the expedition; author Campbell Mackellar; and Guinness baron Lord Iveagh, whose contribution was secured less than two weeks before the departure of the expedition ship Nimrod. On 4 August 1907, Shackleton was appointed a Member of the Royal Victorian Order, 4th Class (MVO; the present-day grade of Lieutenant). CANNOTANSWER
