Bradbury died in Los Angeles, California, on June 5, 2012, at the age of 91, after a lengthy illness. Bradbury's personal library was willed to the Waukegan Public Library, where he had many of his formative reading experiences.
The New York Times ' obituary stated that Bradbury was "the writer most responsible for bringing modern science fiction into the literary mainstream." The Los Angeles Times credited Bradbury with the ability "to write lyrically and evocatively of lands an imagination away, worlds he anchored in the here and now with a sense of visual clarity and small-town familiarity". Bradbury's grandson, Danny Karapetian, stated that Bradbury's works had "influenced so many artists, writers, teachers, scientists, and it's always really touching and comforting to hear their stories". The Washington Post hallmarked several modern day technologies that Bradbury had envisioned much earlier in his writing, such as the idea of banking ATMs and earbuds and Bluetooth headsets from Fahrenheit 451, and the concepts of artificial intelligence within I Sing the Body Electric.
On June 6, 2012, in an official public statement from the White House Press Office, President Barack Obama said:
For many Americans, the news of Ray Bradbury's death immediately brought to mind images from his work, imprinted in our minds, often from a young age. His gift for storytelling reshaped our culture and expanded our world. But Ray also understood that our imaginations could be used as a tool for better understanding, a vehicle for change, and an expression of our most cherished values. There is no doubt that Ray will continue to inspire many more generations with his writing, and our thoughts and prayers are with his family and friends.
Several celebrity fans of Bradbury paid tribute to the author by stating the influence of his works on their own careers and creations. Filmmaker Steven Spielberg stated that Bradbury was "[his] muse for the better part of [his] sci-fi career.... On the world of science fiction and fantasy and imagination he is immortal". Writer Neil Gaiman felt that "the landscape of the world we live in would have been diminished if we had not had him in our world". Author Stephen King released a statement on his website saying, "Ray Bradbury wrote three great novels and three hundred great stories. One of the latter was called 'A Sound of Thunder.' The sound I hear today is the thunder of a giant's footsteps fading away. But the novels and stories remain, in all their resonance and strange beauty." Bradbury's influence well exceeded the field of literature. Progressive house music producer and performer, Joel Thomas Zimmerman, who is most commonly known by his stage name Deadmau5, composed a song named after one of Bradbury's short stories "The Veldt" which was originally published in the Saturday Evening Post. The EP of "The Veldt" was released days after Bradbury's death and is dedicated to the memory of the author.
