It was discovered by the Belgian Antarctic Expedition, 1897–99, under Adrien de Gerlache, but apparently not named by them until about 1904, when in working up their scientific reports they gave it the name Trooz.
In the meantime, Charcot's French Antarctic Expedition, 1903–05, left for the Antarctic and in November 1904 resighted the same cape, to which they gave the name Trois Pérez, for the brothers Fernando, Leopoldo and Manuel Pérez of Buenos Aires.
Maurice Bongrain in his report of 1914 acknowledges the Belgian name Trooz for this cape.
The name Sommet du Grand Pérez was given by J.B. Charcot during the French Antarctic Expedition, 1908–10.
