Stanisław Lem was a Polish writer of science fiction, philosophy and satire. He was named a Knight of the Order of the White Eagle. His books have been translated into 41 languages and have sold over 27 million copies. He is perhaps best known as the author of the 1961 novel Solaris, which has been made into a feature film three times. In 1976, Theodore Sturgeon claimed that Lem was the most widely read science-fiction writer in the world. His works explore philosophical themes; speculation on technology, the nature of intelligence, the impossibility of mutual communication and understanding, despair about human limitations and humankind's place in the universe. They are sometimes presented as fiction, but others are in the form of essays or philosophical books. Translations of his works are difficult due to passages with elaborate word formation, alien or robotic poetry, and puns. Multiple translated versions of his works exist.
