Events
During his time as CEO of Aperture Science, he learned the hard way that manipulating things with moon dust was dangerous.

After being diagnosed with an incurable disease, he planned on pushing forward the GLaDOS project to give himself immortality through brain-mapping his mind into a robot body. But it would take years to be completed and he wouldn't last long enough.

Before leaving Aperture, he left Caroline as the new CEO with express orders to his employees to force her to be used for brain-mapping if he didn't make it.

Sven Co-op contacted him in 1982, days before he was expected to die, with a promise of a chance to cure him. He was given a time and address.

To his surprise, when he arrived to the meeting, he found Caroline between the other recruits. Although the GLaDOS project was still not ready to be activated, it was ready enough to copy her mind onto it shortly after she became the new CEO (and then unbecame it leaving Aperture in a bit of a disarray).

Sven Co-op knew that if he was cured, a good leader would always need his sidekick. Even if this one was still resentful.
