Stanisław Herman Lem was a Polish writer renowned for his philosophical and satirical works, particularly in the realm of science fiction. He authored numerous novels, short stories, and essays on a wide array of topics, including philosophy, futurology, and literary criticism.

Many of Lem's science fiction tales are imbued with satirical and humorous elements. His works have been translated into more than 50 languages and have sold over 45 million copies worldwide. He is perhaps best known as the author of the 1961 novel Solaris, which established his reputation on an international scale.

In 1976, Theodore Sturgeon declared that Lem was the most widely read science fiction writer globally. Among his prominent philosophical works is Summa Technologiae, where he foresaw developments such as virtual reality and artificial intelligence, and explored concepts like human autoevolution and the creation of artificial worlds.

Lem’s science fiction delves into philosophical themes, speculating about technology, the nature of intelligence, and the challenges of communicating with and comprehending alien intelligence. His works also express concerns about human limitations and humanity's place in the universe. Translating his works is notably challenging due to his intricate neologisms and idiomatic expressions.

In recognition of his contributions, the Sejm (the lower house of the Polish Parliament) declared 2021 as Stanisław Lem Year.
