BRITISH ANTARCTIC EXPEDITION, 1907-1909 -- ERIC STEWART MARSHALL (1879-1963)

Marshall was surgeon, cartographer and photographer on Shackleton's Nimrod expediton, as well as a member of the Southern Party. In the hut at Cape Royds he concocted 'forced march' tablets, a cocaine preparation that would help see Shackleton, Wild, Adams and Marshall through to their depots after they had exhausted their rations on the desperate march back from their Farthest South of latitude 88° 23' South, longitude 162° East in January 1909.
