GLaDOS

In 1982, version 1.07, and later 1.07a and 1.09 of me, was operating Aperture Science's Enrichment Center Test Subject Application Process. In 1986, while Aperture Science is working on the 'Portal' project, one of Cave Johnson's dying wishes, they learn of Black Mesa's work on a similar portal technology. In response to this, construction of the first Genetic Lifeform and Disk Operating System (me) begins in the Aperture Laboratories with the aim of accelerating the 'Portal' project, and beat our rival company. In 1996, after a decade spent bringing the Disk Operating System parts to a state of more or less basic functionality, work begins on the Genetic Lifeform component. During that time, the Aperture Science Red Phone plan is implemented in case I appear to become sentient and godlike, requiring an employee to sit by a red phone on a desk in my chamber's entrance hall. In 1997, my current version is 3.11. I was recently murdered by [REDACTED] though.
