Ernest Shackleton [SEP] "Discovery" expedition, 1901–1903
The British National Antarctic Expedition, known as the "Discovery" expedition after the ship , was the brainchild of Sir Clements Markham, president of the Royal Geographical Society, and had been many years in preparation. It was led by Robert Falcon Scott, a Royal Navy torpedo lieutenant lately promoted commander, and had objectives that included scientific and geographical discovery. Although "Discovery" was not a Royal Navy unit, Scott required the crew, officers and scientific staff to submit to the conditions of the Naval Discipline Act, and the ship and expedition were run on Royal Navy lines. Shackleton accepted this, even though his own background and instincts favoured a different, more informal style of leadership.
