First Visitors

The island was discovered by the French Antarctic Expedition (1908–1910) under Jean-Baptiste Charcot and named by him for the wife of Sub-Lieutenant Maurice Bongrain, French Navy, second officer of the expedition. Charcot had climbed to the top of the islands ice cliffs to understand that the outlying Adelaide Island was indeed an island.^[2] Following he had made expeditions into nearby havens to find a wintering harbor but each time was forced to return to Jenny Island until eventually he moved on.^[3]

Wildlife

From time to time Southern elephant seals^[4] take refuge on the island to bathe in the sun and the occasional penguin visits also.
