\" \" September 1921: Sir Ernest Shackleton waves goodbye as he embarks on the Shackleton-Rault Expedition to the Antarctic. But do you know what eventually did in the adventurous Sir Ernest, six years later, back on South Georgia at the beginning of another expedition? And then, in 1922, six years after the legendary rescues of the Endurance expedition, Shackleton died of an \"angina pectoris\" — technically, a chest pain — according to an Associated Press report at the time. NOW THAT'S COOL After his death in 1916, at his wife's request, Shackleton was buried on South Georgia in a whaler's cemetery. He wrote once to my grandmother, 'I'm not much good at anything else but being an explorer,'\" Alexandra Shackleton told PBS in 2002 .
