Theodore Sturgeon (February 26, 1918 – May 8, 1985) was an American science fiction writer and short story master, known for his unique narrative style and profound humanistic concerns. Born in Staten Island, New York, as Edward Hamilton Waldo, he later adopted his stepfather's surname. Active from the 1940s to the 1970s, Sturgeon wrote classic stories like 'Microcosmic God' and 'More Than Human,' and coined 'Sturgeon's Law'—'90% of science fiction is crud, but then 90% of everything is crud.' His works explored human nature, emotion, and social margins, deeply influencing later SF. He won Hugo and Nebula Awards and is often called 'the Shakespeare of science fiction.'
