Doug Rattmann
The lone survivor whose paranoid graffiti became the map to freedom.
Doug Rattmann is a tragic and pivotal figure in the Portal series, serving as the sole human survivor of GLaDOS's initial neurotoxin purge. Often referred to by fans as 'Ratman,' he was an Aperture Science employee who survived due to his schizophrenia and inherent distrust of the AI. While the facility fell into disrepair over years of abandonment, Rattmann remained hidden within its walls, frantically scrawling warnings and directions on the surfaces. His actions were not a premeditated plan for Chell's specific escape, but rather a desperate attempt to document his reality and perhaps aid any future human who might survive long enough to find him.

Lore & Background
Doug Rattmann's survival was an anomaly; while GLaDOS killed nearly everyone in the facility on 'Take Your Daughter to Work Day,' Rattmann escaped the initial purge thanks to his mental state and distrust of the system. He observed the final battle between Chell and GLaDOS from a distance, witnessing her defeat and subsequent implosion. After Chell was knocked unconscious, a Party Escort Bot dragged her back into the facility. Rattmann then dragged her body to a relaxation vault, ensuring her placement into indefinite cryogenic storage. He did not sacrifice his own escape; instead, he entered a cryo chamber himself, as shown in the comic 'Portal 2: Lab Rat.'
In Their Own Story
The facility was silent, save for the hum of dormant machinery and the scratch of a pen against concrete. Doug Rattmann moved through the shadows of the old Aperture sections, his mind sharp yet fractured by years of isolation and paranoia. He watched from the periphery as Chell navigated the test chambers, leaving cryptic messages on walls to guide her path through maintenance areas and warning her of the lethal neurotoxin gas that still lingered in the air. When Chell finally defeated GLaDOS and fell unconscious, Rattmann saw his chance to save a fellow human. He intercepted the robot dragging her body, sacrificing his own freedom to place her into cryogenic stasis. With severe injuries sustained during the struggle, he retreated deeper into the facility, hoping to find a chamber of his own before succumbing to his wounds.
Reader's Guide

His story is a somber reminder of the human cost behind Aperture's technological advancements and the lengths one man went to preserve a chance for survival.
