Naomi Uemura
Naomi Uemura was a Japanese adventurer. He was particularly well known for doing alone what had previously been achieved only with large teams. For example, he was the first man to reach the North Pole solo, the first man to raft the Amazon solo, and the first man to climb Denali solo. He disappeared a day after his 43rd birthday while attempting to climb Denali in the winter.
