John Michael Crichton (October 23, 1942 – November 4, 2008), best known as Michael Crichton, was an American author, producer, director, and screenwriter, best known for his work in the science fiction, medical fiction, and thriller genres. His books have sold over 150 million copies worldwide, and many have been adapted into films. In 1994, Crichton became the only creative artist ever to have works simultaneously charting at #1 in television, film, and book sales (with ER, Jurassic Park, and Disclosure, respectively).

His literary works are usually based on the action genre and heavily feature technology. His novels epitomize the techno-thriller genre of literature, often exploring technology and failures of human interaction with it, especially resulting in catastrophes with biotechnology. Many of his future history novels have medical or scientific underpinnings, reflecting his medical training and science background. He was the author of, among others, Jurassic Park, The Andromeda Strain, Congo, Travels, Sphere, Rising Sun, Disclosure, The Lost World, Airframe, Timeline, Prey, State of Fear, Next (the final book published before his death), Pirate Latitudes (published November 24, 2009), and a final unfinished techno-thriller yet to be released. Forbes listed Crichton in tenth place in its list of "Top-Earning Dead Celebrities" of 2009.
