This is so sad. He was best known of course, for his sci fi works like Jurassic Park and West World, but he was a wonderful author and talent. He died at the young age of 66 from what he described as his personal battle with cancer. He was also the writer, creator and director of the TV show ER. He attended and graduated medical school but never did a residency and went into writing instead. I will miss his continuing work very much.
