Jack Vance

Sci-fi author Jack Vance passed away over the weekend at the age of 96. I've never read any of his work, but the early TSR folks were big Vance fans, and some of his ideas were adapted into the D&D game rules. The notion that wizards and other spell-casters must memorize spells that subsequently disappear from their memories once cast is an idea straight from Vance. He's honored in D&D mythology by the god Vecna, whose name is an anagram of Vance.
