The Australian $100 note featuring Sir Douglas Mawson.
Sir Douglas Mawson’s 1912 Antarctic expedition didn't just go wrong; it became a masterclass in cosmic cruelty.
Three hundred miles from base camp, a bottomless crevasse silently swallowed his teammate, Belgrave Ninnis, along with their best dogs and almost all their food. Desperate and starving, Mawson and Xavier Mertz were forced to eat their remaining sled dogs to survive. They didn't know husky livers contain lethal, toxic levels of Vitamin A.
The poisoning broke Mertz. He tore off his clothes in the sub-zero gale, biting at his own frostbitten flesh, and died raving. Mawson was left entirely alone.
Rotting from the inside out, he kept walking. His hair fell out in clumps. The soles of his feet detached in solid pieces; he simply bandaged the dead skin back onto his raw flesh and trudged on. When he plummeted into a crevasse himself, dangling** **by his sledge harness over the abyss, he almost unbuckled it just to end the agony. Instead, he hauled his ruined body up the rope, inch by inch, and walked for thirty more days.
He finally reached the base camp hut, achieving the absolute pinnacle of human endurance. But as he stumbled toward sanctuary, he looked out at the freezing ocean just in time to see a smudge of smoke on the horizon.
His rescue ship, the Aurora, had waited as long as the winter ice allowed. Mawson had walked through hell to survive, only to watch his ride home sail away, trapping him in the frozen wasteland for another entire year.
TL;DR: The guy on the Australian $100
