@Evelyne Vincent Yes! https://www.mos.ru/en/news/item/159891073/ Fedor Konyukhov mentioned about him here "Is this going to be another solo trip? Why do you prefer such expeditions and travel without companions? — Yes, certainly. Why am I traveling alone? This way I only risk my own life, and I can go all the way. In a team, you’re always responsible for other people’s lives. For example, in 1978, Japanese traveler Naomi Uemura was the first to reach the North Pole alone. He, you could say, became my teacher. And then Frenchman Jean-Louis Etienne reached the North Pole, also alone. And the third person was me." Great people!
