 Official biographies
- Steve Theodore - Game Designer/Animator
- Steve Theodore comes to Valve from FASA Interactive in Chicago, where he made BattleMechs (tm) for FASA Interactive's MechCommander and the ill-fated MechWarrior III. He's probably the only animator you'll ever meet with a degree in Roman History and a reading knowledge of ancient Greek. Despite his professorial manner, Steve was a member of Chicago's famous art-rock trio, "The Chimps" and was feared and hated by his former landlady.
