Ray Bradbury was married to Marguerite McClure (January 16, 1922 – November 24, 2003) from 1947 until her death; they had four daughters: Susan, Ramona, Bettina and Alexandra. Though he lived in Los Angeles, Bradbury never obtained a driver's license but relied on public transportation or his bicycle. He lived at home until he was twenty-seven and married. His wife of fifty-six years, Maggie, as she was affectionately called, was the only woman Bradbury ever dated.
Bradbury was a close friend of Charles Addams, and Addams illustrated the first of Bradbury's stories about the Elliotts, a family that would resemble Addams' own Addams Family placed in rural Illinois. Bradbury's first story about them was "Homecoming," published in the 1946 Halloween issue of Mademoiselle, with Addams illustrations. He and Addams planned a larger collaborative work that would tell the family's complete history, but it never materialized, and according to a 2001 interview, they went their separate ways. In October 2001, Bradbury published all the Family stories he had written in one book with a connecting narrative, From the Dust Returned, featuring a wraparound Addams cover of the original "Homecoming" illustration.
Another close friend was animator Ray Harryhausen, who was best man at Bradbury's wedding. During a BAFTA 2010 awards tribute in honor of Ray Harryhausen's 90th birthday, Bradbury spoke of his first meeting Harryhausen at Forrest J Ackerman's house when they were both 18 years old. Their shared love for science fiction, King Kong, and the King Vidor-directed film The Fountainhead, written by Ayn Rand, was the beginning of a lifelong friendship. These early influences inspired the pair to believe in themselves and affirm their career choices. After their first meeting, they kept in touch at least once a month, in a friendship that spanned over 70 years.
Late in life, Bradbury retained his dedication and passion despite what he described as the "devastation of illnesses and deaths of many good friends." Among the losses that deeply grieved Bradbury was the death of Star Trek creator Gene Roddenberry, who was an intimate friend for many years. They remained close friends for nearly three decades after Roddenberry asked him to write for Star Trek, which Bradbury never did, objecting that he "never had the ability to adapt other people's ideas into any sensible form."
Bradbury suffered a stroke in 1999 that left him partially dependent on a wheelchair for mobility. Despite this he continued to write, and had even written an essay for The New Yorker, about his inspiration for writing, published only a week prior to his death. Bradbury made regular appearances at science fiction conventions until 2009, when he retired from the circuit.
Bradbury chose a burial place at Westwood Village Memorial Park Cemetery in Los Angeles, with a headstone that reads "Author of Fahrenheit 451". On February 6, 2015, the New York Times reported that the house that Bradbury lived and wrote in for fifty years of his life, at 10265 Cheviot Drive in Los Angeles, CA, had been demolished.
