Ernest Shackleton was born in County Kildare, Ireland, in 1874.
In 1901, alongside explorer Robert Falcon Scott, he got closer to the South Pole than any other European explorer.
Shackleton’s most famous mission was his plan to cross the South Pole on board his ship The Endurance.
In 1915, the boat became trapped in ice, and his crew abandoned ship, crossing onto floating ice, where they decided they were going to live until they could be saved.
In April 1916, Shackleton took five crew members in a small boat in search of help for the others, where they travelled 807 miles (1,300km) of ocean before reaching the island of South Georgia.
The last voyage Ernest Shackleton took was on board the Quest in 1922.
He had planned to explore Alaska and islands nearby, but lost his funding.
Instead, he headed to the South Pole to explore islands around Antarctica but died of a heart attack on board the ship, aged 47.
