LOS ANGELES — Ray Bradbury, the science fiction-fantasy master who transformed his childhood dreams and Cold War fears into telepathic Martians, lovesick sea monsters, and the high-tech, book-burning future of “Fahrenheit 451,” has died. He was 91.

He died Tuesday night, his daughter said this morning. Alexandra Bradbury did not have additional details.

His writings ranged from horror and mystery to humor and sympathetic stories about the Irish, blacks and Mexican-Americans. Bradbury also scripted John Huston’s 1956 film version of “Moby Dick” and wrote for “The Twilight Zone” and other television programs, including “The Ray Bradbury Theater.”

“What I have always been is a hybrid author,” Bradbury said in 2009. “I am completely in love with movies, and I am completely in love with theater, and I am completely in love with libraries.”

Bradbury broke through in 1950 with “The Martian Chronicles,” a series of intertwined stories that satirized capitalism, racism and superpower tensions as it portrayed Earth colonizers destroying an idyllic Martian civilization.

“The Martian Chronicles” prophesized the banning of books, especially works of fantasy, a theme Bradbury would take on fully in the 1953 release, “Fahrenheit 451.”

Bradbury had been told that 451 degrees Fahrenheit was the temperature at which texts went up in flames.
