Wrote "O.H.M.S. An Illustrated Record of the Voyage of S.S. Tintagel Castle" as a young man. Served under Scott on Discovery on the British National Antarctic Expedition and accompanied Scott to attain the then furthest south. Attained a new furthest south, commanding his own expedition in the Nimrod, and recorded his experiences in "The Heart of the Antarctic" and edited and contributed to a book printed in the Antarctic "Aurora Australis". His best known expedition was to be a transcontinental traverse of Antarctica but his ship, the Endurance, was crush in the ice and he never made landfall. He and his men lived on ice floes and eventually took a perilous journey in small boats to make landfall. Shacklton then led a much smaller party in a single small boat through the roughest seas on earth and crossed an uncharted mountainous island to reach help. His record of this epic struggle for survival is presented in his book "South".
