Józef Jerzy Kukuczka was a Polish mountaineer. He was born in Katowice, his family was ethnically Silesian Goral. On 18 September 1987, he became the second man to climb all fourteen eight-thousanders in the world; a feat which took him less than 8 years to accomplish. He is the only person to have climbed two eight-thousanders in one winter. Altogether, he ascended four eight-thousanders in winter, including three as first ascents. Along with Tadeusz Piotrowski, Kukuczka established a new route on K2 in alpine style, which no one has repeated.

Lhotse is the fourth-highest mountain on Earth, after Mount Everest, K2, and Kangchenjunga. At an elevation of 8,516 metres (27,940 ft) above sea level, the main summit is on the border between Tibet Autonomous Region of China and the Khumbu region of Nepal.
