Józef Jerzy Kukuczka (24 March 1948 in Katowice, Poland - 24 October 1989 Lhotse, Nepal) was a Polish alpine and high-altitude climber. Born in Katowice, his family origin is Silesian Goral. On 18 September 1987, he became the second man (after Reinhold Messner), 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 in the world who has 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 (the so-called Polish Line), which no one has repeated.
