Michael Crichton, the million-selling author who made scientific research terrifying and irresistible in such thrillers as “Jurassic Park,” “Timeline” and “The Andromeda Strain,” has died of cancer, his family said.

Crichton died Tuesday in Los Angeles at age 66 after privately battling cancer.

“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,” his family said in a 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 was an experimenter and popularizer known for his stories of disaster and systematic breakdown, such as the rampant microbe of “The Andromeda Strain” or the dinosaurs running madly in “Jurassic Park.” Many of his books became major Hollywood movies, including “Jurassic Park,” “Rising Sun” and “Disclosure.” Crichton himself directed and wrote “The Great Train Robbery” and he co-wrote the script for the blockbuster “Twister.”

In 1994, he created the award-winning TV hospital series “ER.” He’s even had a dinosaur named for him, Crichton’s ankylosaur.

“Michael’s talent out-scaled even his own dinosaurs of ‘Jurassic Park,”‘ said “Jurassic Park” director Steven Spielberg, a friend of Crichton’s for 40 years. “He was the greatest at blending science with big theatrical concepts, which is what gave credibility to dinosaurs again walking the Earth. … Michael was a gentle soul who reserved his flamboyant side for his novels. There is no one in the wings that will ever take his place.”

In recent years, Crichton was the rare novelist granted a White House meeting with President Bush, perhaps because of his skepticism about global warming, which Crichton addressed in the 2004 novel, “State of Fear.” Crichton’s views were strongly condemned by environmentalists, who alleged that the author was hurting efforts to pass legislation to reduce emissions of carbon dioxide.

If not a literary giant, he was a physical one, standing 6 feet and 9 inches, and ready for battle with the press. In a 2004 interview with The Associated Press, Crichton came with a tape recorder, text books and a pile of graphs and charts as he defended “State of Fear” and his take on global warming.

“I have a lot of trouble with things that don’t seem true to me,” Crichton said at the time, his large, manicured hands gesturing to his graphs. “I’m very uncomfortable just accepting. There’s something in me that wants to pound the table and say, ‘That’s not true.”‘

He spoke to few scientists about his questions, convinced that he could interpret the data himself. “If we put everything in the hands of experts and if we say that as intelligent outsiders, we are not qualified to look over the shoulder of anybody, then we’re in some kind of really weird world,” he said.

A new novel by Crichton had been tentatively scheduled to come next month, but publisher HarperCollins said the book was postponed indefinitely because of his illness.

Crichton was married five times and had one child. A private funeral is planned.
