For whatever reason, Paul Steed is one of those early internet era gaming "celebrities" I remember well, back when .plan files were the best way to follow game developers.
He was an artist/modeler for the Wing Commander and Quake series, and designed the infamous "Crackwhore" Quake 2 model. After getting sacked at id due to an internal power struggle over Doom 3, he eventually landed at Microsoft as Creative Director for the Xbox 360.
No word on cause of death, but he was certainly too young.
