For more than a century, brave men and women have made unimaginably difficult treks to Antarctica, inspiring some of them to chronicle their experiences on the harshest continent. Among the highlights here are Roald Amundsen on his historic attainment of the Pole, Ernest Shackleton on the loss of the Endurance, Robert Falcon Scott's final letters to loved ones, Richard E. Byrd on his daring flight, T.W. Edgeworth David recounting his ascent of Mount Erebus, and Lynne Cox on her epic 2002 swim.
