Michael Crichton, author of 'Jurassic Park' and creator of the television series 'ER', has died at the age of 66.
Crichton, who was a medical doctor before he became a novelist, died "unexpectedly" following a private battle with cancer, according to a family statement.
The author's family said that he died on Tuesday in Los Angeles, asking for privacy at this time.
A statement said: "While the world knew him as a great story teller that challenged our preconceived notions about the world around us - and entertained us all while doing so - his wife Sherri, daughter Taylor, family and friends knew Michael Crichton as a devoted husband, loving father and generous friend who inspired each of us to strive to see the wonders of our world through new eyes."
"He did this with a wry sense of humour that those who were privileged to know him personally will never forget."
'The Andromeda Strain', published in 1969, was Crichton's first best-seller.
He also wrote 'Jurassic Park' and 'The Lost World', which became Hollywood films, 'Congo', 'The Terminal Man', 'Prey' and 'State of Fear'.
In 1996 Crichton also won an Emmy for the television drama 'ER'.
