Question: Who captained the ship with the man, in which McIlroy Peak is named after, during the 1914 Antarctic Expedition?
Context: Hamartind Peak ( ) is a peak, 2885 m high, at the eastern extremity of the Hamrane Heights, in the Sverdrup Mountains of Queen Maud Land, Antarctica.  The peak was potographed from the air by the Third German Antarctic Expedition (1938–39).  It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–52) and from air photos by the Sixth Norwegian Antarctic Expedition (1958–59) and named Hamartind (the crag peak). Daykovaya Peak ( ) is a prominent peak, 1,995 m high, rising between Mount Hansen and Kare Bench in the Westliche Petermann Range, Wohlthat Mountains.  It was discovered and plotted from air photos by the Third German Antarctic Expedition, 1938–39.  It was mapped from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1956–60; remapped by the Soviet Antarctic Expedition, 1960–61, and named "Gora Daykovaya" (dike mountain). Français Glacier ( ) is a glacier 4 nmi wide and 12 nmi long, flowing north-northeast from the continental ice to the Antarctic coast close west of Ravin Bay.  Though no glaciers were noted on Captain Jules Dumont d'Urville's chart of this coast, the close correlation of his "Baie des Ravins" feature and narrative description with the indentation of the coast near the mouth of this glacier suggests first sighting of this feature by the French Antarctic Expedition, 1837–40.  During December 1912 members of the Main Base Party of the Australasian Antarctic Expedition (AAE) camped on the upland slopes close east of the glacier, but no reference was made to the glacier in the AAE reports, though a clear view and unpublished sketch were obtained of the distant coast to the northwest.  It was delineated from air photos taken by U.S. Navy Operation Highjump, 1946–47.  The French Antarctic Expedition under Mario Marret, 1952–53, sledged west on the sea ice to the ice cliffs close east of the glacier.  It was named after the "Français", the expedition ship of the French Antarctic Expedition, 1903–05, under Dr. Jean-Baptiste Charcot. Terletskiy Peak ( ) is a peak, 2,505 m, rising 1.7 nautical miles (3.1 km) northwest of Chervov Peak in the Shcherbakov Range, Orvin Mountains, in Queen Maud Land.  Discovered and roughly plotted from air photos by German Antarctic Expedition, 1938-39.  Mapped from air photos and surveys by Norwegian Antarctic Expedition, 1956-60 remapped by Soviet Antarctic Expedition, 1960–61, and named after Soviet hydrographer N.A. Terletskiy (1910–1954). McIlroy Peak ( ) is a peak rising to 745 m west of Husvik Harbour and 0.8 nmi south of Mount Barren, South Georgia.  It was named by the UK Antarctic Place-Names Committee in 1990 after Dr. James A. McIlroy, surgeon on the British Imperial Trans-Antarctic Expedition, 1914–16, in the "Endurance", and on the Shackleton–Rowett Expedition, 1921–22, in the "Quest". Endurance was the three-masted barquentine in which Sir Ernest Shackleton sailed for the Antarctic on the 1914 Imperial Trans-Antarctic Expedition.  She was launched in 1912 from Sandefjord in Norway and was crushed by ice, causing her to sink three years later in the Weddell Sea off Antarctica. Chervov Peak ( ) is a peak, 2,550 m high, rising 1 nmi north of Morkenatten Peak in the Shcherbakov Range of the Orvin Mountains, in Queen Maud Land.  It was roughly plotted from air photos by the Third German Antarctic Expedition, 1938–39.  It was mapped from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1956–60, remapped by the Soviet Antarctic Expedition, 1960–61, and named after Soviet geologist Ye.  I. Chervov. Mechnikov Peak ( ) is a prominent peak, 2,365 m high, at the base of the spur separating Schussel Cirque and Grautskåla Cirque in the Humboldt Mountains of Queen Maud Land, Antarctica.  It was discovered and plotted from air photos by the Third German Antarctic Expedition, 1938–39, and was mapped from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1956–60.  The peak was remapped by the Soviet Antarctic Expedition, 1960–61, and named after Russian geographer L.I. Mechnikov, 1838–88. Sverre Peak ( ) is a small peak 0.5 nautical miles (0.9 km) off the north end of Pettersen Ridge in the Conrad Mountains of Queen Maud Land.  Discovered and photographed by the German Antarctic Expedition, 1938-39.  Mapped by Norway from air photos and surveys by the Norwegian Antarctic Expedition, 1956–60, and named for Sverre Pettersen, steward with Norwegian Antarctic Expedition, 1957-58. Taborovskiy Peak ( ) is the highest peak, at 2,895 m, in the Skarshaugane Peaks of the Betekhtin Range, Humboldt Mountains, in Queen Maud Land.  It was discovered and plotted from air photos by German Antarctic Expedition, 1938-39.  The peak was mapped from air photos and surveys by Norwegian Antarctic Expedition, 1956–60; remapped by Soviet Antarctic Expedition, 1960–61, and named after Soviet meteorologist N.L. Taborovskiy.
