==<br /> About ==

<blockquote>
Jeff Stephenson Designer & Programmer 1982-1993 was one of the company's first employees, Jeff Stephenson created [[SCI]], the object-oriented scripting language of Sierra On-Line for its adventure games after the older [[AGI]] (for which he is also partly responsible for), 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, before it became known as ''Sierra Creative Interpreter''.
