Task: Question Answering
Input (English): Passage: After Shackleton left with the James Caird, Frank Wild took command of the Elephant Island party, some of whom were in a low state, physically or mentally: Lewis Rickinson had suffered a suspected heart attack; Perce Blackborow was unable to walk, due to frostbitten feet; Hubert Hudson was depressed. The priority for the party was a permanent shelter against the rapidly approaching southern winter. On the suggestion of George Marston and Lionel Greenstreet, a hut—nicknamed the "Snuggery"—was improvised by upturning the two boats and placing them on low stone walls, to provide around five feet (1.5 m) of headroom. By means of canvas and other materials the structure was made into a crude but effective shelter.Wild initially estimated that they would have to wait one month for rescue, and refused to allow long-term stockpiling of seal and penguin meat because this, in his view, was defeatist. This policy led to sharp disagreements with Thomas Orde-Lees, who was not a popular man and whose presence apparently did little to improve the morale of his companions, unless it was by way of being the butt of their jokes.As the weeks extended well beyond his initial optimistic forecast, Wild established and maintained routines and activities to relieve the tedium. A permanent lookout was kept for the arrival of the rescue ship, cooking and housekeeping rotas were established, and there were hunting trips for seal and penguin. Concerts were held on Saturdays and anniversaries were celebrated, but there were growing feelings of despondency as time passed with no sign of the ship. The toes on Blackborow's left foot became gangrenous from frostbite and, on 15 June, had to be amputated by surgeons Alexander Macklin and James McIlroy in the candle-lit hut. Using the very last of the chloroform in their medical supplies, the whole procedure took 55 minutes and was a complete success.By 23 August, it seemed that Wild's no-stockpiling policy had failed. The surrounding sea was dense with pack ice that would halt any rescue ship, food supplies were running out and no penguins were coming ashore. Orde-Lees wrote: "We shall have to eat the one who dies first [...] there's many a true word said in jest". Wild's thoughts were now seriously turning to the possibility of a boat trip to Deception Island—he planned to set out on 5 October, in the hoping of meeting a whaling ship— when, on 30 August 1916, the ordeal ended suddenly with the appearance of Shackleton and Yelcho. 
Question: What are the full names of the people who the used very last of the chloroform in their medical supplies?
Output (English): Alexander Macklin.
