Stanisław Lem, one of the most original science fiction writers of the twentieth century, was born on September 12, 1921, in Lwów, which was in the then territory of Poland, today's Lviv city in Ukraine. Lem, who began studying medicine, turned to literature amid the chaos of World War II and Poland's political changes; Over time, this orientation turned him into a pen master known not only in Poland but also throughout the world. Lem's writing adventure began in the late 1940s and he quickly came to the fore as a voice showing how science fiction could meet philosophical depths. Themes such as artificial intelligence, consciousness, the limits of communication and humanity's loneliness in the universe were treated as serious intellectual issues, not just speculative fiction elements, in his works. A prolific writer in the genres of novels, essays, philosophical studies and short stories, Lem's works have been translated into dozens of languages ​​and reached millions of readers around the world. The most striking example in terms of its reflections on cinema is undoubtedly the novel Solaris. This novel, published in 1961, is about how a mysterious planet manipulates the human mind and has solidified its place among the masterpieces of science fiction literature. The novel was adapted into a movie by Soviet director Andrei Tarkovsky in 1972, and combined with the director's poetic language, it became one of the most influential science fiction films of the period. Thirty years later, in 2002, Solaris was brought to the big screen once again in Steven Soderbergh's remake starring George Clooney. The fact that Lem was able to personally observe the distance between these two different interpretations is clear evidence of the universality of his work. In addition, the 1963 Czechoslovakian science fiction film Ikarie XB 1 is also considered among the important productions that establish a dialogue with Lem's universe. The German production Ijon Tichy: Raumpilot (2007) once again demonstrated the permanence of his works in popular culture by bringing his beloved character Ijon Tichy to the screen. Stanisław Lem passed away in Kraków on March 27, 2006. The works he left behind constitute a permanent legacy that shows that science fiction can go far beyond an entertainment tool, on the contrary, it can hold a mirror to humanity's most fundamental existential questions.
