Sean Ellis

From IFWiki

Sean Ellis was a British programmer and creator of the GAC and the STAC.

As a university student his work on an adventure creation system, inspired by the outline in Trevor Tom's The ZX81 Pocket Book, came to the attention of Ian Andrew of Incentive Software. The resulting GAC, written for Incentive and initially released for the Amstrad CPC, was Sean's first commercial project.

Sean went on to code an upgraded version of the system for Atari ST called STAC. He later worked on other projects in the game industry and eventually for ARM as part of their GPU architecture team.

Sean Ellis died in 2020.
