Michael Crichton, American physician, author, director, producer, and screenwriter (b. 1942)
John Michael Crichton (; October 23, 1942 – November 4, 2008) was an American author and filmmaker. His books have sold over 200 million copies worldwide, and over a dozen have been adapted into films. His literary works are usually within the science fiction, techno-thriller, and medical fiction genres, and heavily feature technology. His novels often explore technology and failures of human interaction with it, especially resulting in catastrophes with biotechnology. Many of his novels have medical or scientific underpinnings, reflecting his medical training and scientific background.

Crichton received an M.D. from Harvard Medical School in 1969 but did not practice medicine, choosing to focus on his writing instead. Initially writing under a pseudonym, he eventually wrote 26 novels, including The Andromeda Strain (1969), The Terminal Man (1972), The Great Train Robbery (1975), Congo (1980), Sphere (1987), Jurassic Park (1990), Rising Sun (1992), Disclosure (1994), The Lost World (1995), Airframe (1996), Timeline (1999), Prey (2002), State of Fear (2004), and Next (2006). Several novels, in various states of completion, were published after his death in 2008.

Crichton was also involved in the film and television industry. In 1973, he wrote and directed Westworld, the first film to utilize 2D computer-generated imagery. He also directed Coma (1978), The First Great Train Robbery (1979), Looker (1981), and Runaway (1984). He was the creator of the television series ER (1994–2009), and several of his novels were adapted into films, most notably the Jurassic Park franchise.

He held a contrarian position on various scientific issues such as climate change, the health risks of secondhand smoke, and the search for alien life. Crichton himself framed this contrarianism as a practical skepticism of "consensus-based" science, arguing that over-reliance on statistical models creates the potential for bias, especially in the face of political and social pressures such as the desire to avert nuclear war.
