Crichton, best known for such books as "Jurassic Park" and "Disclosure," also created the hit TV series "ER."
His rep released the following statement: "While the world knew him as a great storyteller 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 humor that those who were privileged to know him personally will never forget.
Through his books, Michael Crichton served as an inspiration to students of all ages, challenged scientists in many fields, and illuminated the mysteries of the world in a way we could all understand.
He will be profoundly missed by those whose lives he touched, but he leaves behind the greatest gifts of a thirst for knowledge, the desire to understand, and the wisdom to use our minds to better our world.
Michael's family respectfully asks for privacy during this difficult time.
A private funeral service is expected, but no further details will be released to the public."
John Wells, Executive Producer of "ER" said, "Michael was an extraordinary man. Brilliant, funny, erudite, gracious, exceptionally inquisitive and always thoughtful. No lunch with Michael lasted less than three hours and no subject was too prosaic or obscure to attract his interest. Sexual politics, medical and scientific ethics, anthropology, archeology, economics, astronomy, astrology, quantum physics, and molecular biology were all regular topics of conversation. I was blessed to have known him and proud to be able to have called him my friend."
