Author of books such as the Andromeda Strain and Jurassic Park, more than a dozen of his novels have been turned into Hollywood blockbusters.
Jurassic Park proved such a success he wrote a sequel, The Lost World.
He also won an Emmy for the popular TV hospital drama ER.
Born in Chicago in 1942, he wrote his first novels while attending Harvard medical school.
His family says a private funeral service will be held for the writer.
