However, the inauguration of the Heroic Age is now generally considered to be an expedition launched by the Belgian Geographical Society in 1897; Borchgrevink followed a year later with a privately sponsored expedition. The designation "Heroic Age" only came much later; the term is not used in any of the early expedition accounts or memoirs, nor in biographies of polar figures involved in the Heroic Age which appeared in the 1920s and 1930s. It is not clear when the term was first coined or adopted generally. It was used in March 1956 by the British explorer Duncan Carse, writing in "The Times". Describing the first crossing of South Georgia by Ernest Shackleton's Imperial Trans-Antarctic Expedition in 1916, Carse wrote of "three men from the heroic age of Antarctic exploration, with 50 feet of rope between them, and a carpenter's adze".
