The Science Fiction and Fantasy Writers Association Reports that Jerry Pournelle died on September 8 at age 84. The article didn't list the cause of death.
He was the first winner of the "Best New Writer" category of the Campbell award, and was a former president of the SFWA, a writer's guild.
I thought his best stuff was his Niven collaborations, like A Mote in God's Eye. What was your favorite?
