Q:Read the following paragraph and extract the answer for the question: What was the full name of the person that had to change their plans when money was withheld?  The Shackleton–Rowett Expedition (1921–22) was Sir Ernest Shackleton's last Antarctic project, and the final episode in the Heroic Age of Antarctic Exploration. The venture, financed by John Quiller Rowett, is sometimes referred to as the Quest Expedition after its ship Quest, a converted Norwegian sealer. Shackleton had originally intended to go to the Arctic and explore the Beaufort Sea, but this plan was abandoned when the Canadian government withheld financial support; Shackleton thereupon switched his attention to the Antarctic. Quest, smaller than any recent Antarctic exploration vessel, soon proved inadequate for its task, and progress south was delayed by its poor sailing performance and by frequent engine problems. Before the expedition's work could properly begin, Shackleton died on board the ship, just after its arrival at the sub-Antarctic island of South Georgia. The major part of the subsequent attenuated expedition was a three-month cruise to the eastern Antarctic, under the leadership of the party's second-in-command, Frank Wild. The shortcomings of Quest were soon in evidence: slow speed, heavy fuel consumption, a tendency to roll in heavy seas, and a steady leak. The ship was unable to proceed further than longitude 20°E, well short of its easterly target, and its engine's low power coupled with its unsuitable bows was insufficient for it to penetrate southward through the pack ice. Following several fruitless attempts, Wild returned the ship to South Georgia, on the way visiting Elephant Island where he and 21 others had been stranded after the sinking of the ship Endurance, during Shackleton's Imperial Trans-Antarctic Expedition six years earlier.

Sir Ernest Shackleton
