. After the French polar explorer Jean-Baptiste Charcot was the first to sight Mount Nicholas in 1909, the American polar explorer Lincoln Ellsworth determined the entire extent of the mountain during an overflight on November 23, 1935. The resulting aerial photographs were used by Ellworth's compatriot WLG Joerg for a rough cartographic survey. The eastern flank of the range was surveyed superficially in 1936 from George VI Sound by participants in the British Graham Land Expedition (1934–1937) under the direction of the Australian polar explorer John Rymill. The Falkland Islands Dependencies Survey undertook a new survey of the area from 1948 to 1950. The entire range, including its western flank, was mapped from aerial photographs taken by the Ronne Antarctic Research Expedition (1947–1948) led by the American polar explorer Finn Ronne. Participants of the British Graham Land Expedition named the mountain range after Admiral Percy Douglas (1876–1939), chairman of the expedition's advisory board.
