The icecapped island is dominated by a truncated pyramidal peak, lying at the southeast entrance to the channel between Brabant Island and Liège Island. It was discovered by the Belgian Antarctic Expedition under Gerlache, 1897–99, and named for Gerard Harry, Belgian journalist and promoter of the expedition. The island was photographed from the air by FIDASE, 1956-57
