Jeff Stephenson

Developer BIO

Jeff Stephenson created SCI (Sierra's Creative Interpreter), the object-oriented scripting language of Sierra On-Line for its adventure games after the older AGI (a procedural language). Previously, he also was the head of Sierra’s AGI and SCI system programmers and responsible for much of the code of both of those languages. He originally called it LSCI, for Large-model Script Code Interpreter, and later SCI because it ran scripts, until someone in marketing found a better way to explain the acronym.

He was one of the company's first employees, struggling through the down times when Sierra almost went under. When Sierra got back on track, development began on King's Quest.

In the early nineties, as Sierra's Lead Programmer, he was also involved with creating TSN (The Sierra Network), later TNN (The ImagiNation Network), the architecture for online games. In 1992, he left the company for good.
