Frank Herbert (1920–1986) was an American science fiction writer best known for creating the Dune universe, one of the most influential and bestselling science fiction series of all time. His work is noted for its deep exploration of politics, religion, ecology, and human evolution.

He helped transform science fiction into a genre capable of serious literary and philosophical exploration. Dune influenced not only science fiction writers but also environmental thinkers, political theorists, and futurists. The novel’s ecological themes were especially ahead of their time and helped popularize environmental awareness in speculative fiction.

His work has also inspired major films, television adaptations, games, and ongoing novels written by his son Brian Herbert and Kevin J. Anderson.
