Scientist. Screenwriter. TV producer. Michael Crichton, who died on Nov. 4 from cancer, had a lot of jobs in his 66 years. But the one that made him most famous, and that will probably keep him famous, is Author. Granted, none of his high-tech thrillers won him much respect from literary snobs. His work in Hollywood — creating ER, co-writing the script for Twister — probably made him more money. But as anybody who has ever picked up one of his books knows all too well, the guy sure knew how to tap out a page-turner.
