Jerzy Kukuczka (24 March 1948 in Katowice, Poland – 24 October 1989 Lhotse, Nepal) was a Polish alpine and high-altitude climber. On 18 September 1987, he became the second man (after Reinhold Messner), to climb all fourteen eight-thousanders in the world, it took him almost 8 years. He is the only person in the world who has climbed two eight-thousanders in one winter. He ascended four eight-thousanders in the winter altogether, including three in winter for the first time. Along with Tadeusz Piotrowski, Kukuczka established a new route on K2 in alpine style (the so-called "Polish Line"), which no one has ever repeated.
