Editing Ernest Shackleton (section)

=== Biding time ===
[[File:Shackleton lecture poster.jpg|thumb|upright=1.1|Shackleton embarked on an extensive lecture tour in which he talked not only about his own polar journeys but also those of Scott and [[Roald Amundsen]].|alt=A poster advertising a talk presented by Shackleton]]
In the period immediately after his return, Shackleton engaged in a strenuous schedule of public appearances, lectures and social engagements. He then sought to cash in on his celebrity by making a fortune in the world of business.{{sfn|Fisher|Fisher|1957|pp=284–285}} Among the ventures that he hoped to promote were a tobacco company,{{sfn|Huntford|1985|pp=351–352}} a scheme for selling special postage stamps to collectors—overprinted "King Edward VII Land", based on his appointment as Antarctic [[postmaster]] by the New Zealand authorities{{sfn|Huntford|1985|p=312}}—and the development of a Hungarian mining concession he had acquired near the city of [[Nagybanya]], now part of [[Romania]].{{sfn|Huntford|1985|pp=323–326}}

As none of these enterprises prospered, Shackleton's main source of income was his earnings from lecture tours. He still harboured thoughts of returning south, even though in September 1910, having recently moved with his family to [[Sheringham]] in Norfolk, he wrote to Emily: "I am never again going South and I have thought it all out and my place is at home now."{{sfn|Fisher|Fisher|1957|pp=284–285}} He had been in discussions with Douglas Mawson about a scientific expedition to the Antarctic coast between [[Cape Adare]] and [[Gaussberg]], and had written to the RGS about this in February 1910.{{efn|name=Mawson's expedition}}{{sfn|Riffenburgh|2004|p=298}}

Any future resumption by Shackleton of his quest for the South Pole depended on the results of Scott's [[Terra Nova Expedition|''Terra Nova'' Expedition]], which had sailed from Cardiff on 15&nbsp;June 1910.{{sfn|Turley|1914|p=211}} By early 1912, the world was aware that the pole had been conquered by the Norwegian Roald Amundsen, but the fate of Scott's expedition was not then known.<ref>{{cite web|url=https://www.rmg.co.uk/stories/topics/race-south-pole-scott-amundsen |title=The race to the South Pole: Scott and Amundsen |work=Royal Museums Greenwich |access-date=9 February 2024 |quote=[On] 14 December 1911, Amundsen raised the flag of Norway at the South Pole.

Bruce had failed to acquire financial backing, and was happy for Shackleton to adopt his plans,{{sfn|Huntford|1985|p=367}} which were similar to those being followed by the German explorer [[Wilhelm Filchner]] who had left [[Bremerhaven]] in May 1911; in December 1912, the news arrived from [[South Georgia]] that Filchner's expedition had failed.{{efn|name=Filchner's expedition}}{{sfn|Huntford|1985|p=367}} In Shackleton's own words, the transcontinental journey was the "one great main object of Antarctic journeyings" remaining, and now open to him.{{sfn|Shackleton, ''South''|loc=preface, p. vii}}
