Cave Johnson



Cave Johnson is the founder of Aperture Science, which was built from Aperture Science Innovations. He was briefly mentioned in Portal, but becomes a more prominent character in Portal 2, in the form of tape recordings he leaves behind.

Shower curtains
In 1953 Cave Johnson sets up Aperture Fixtures, a shower curtain manufacturer. The precursor to Aperture Science, he chooses the name because it 'makes the curtains sound more hygienic'. He becomes a billionaire after winning contracts to manufacture the US Military's shower curtains.

Aperture Science Innovations
During his career in science, he called on the wealthy or power elite to join his cause for the future of science, as well as those with the brains, much like Caroline, and those lacking common sense for the dangers of science.

Aperture
At the time of creation, Aperture Science Innovations had created a prototype to the modern Handheld Portal Device Chell wields.

Aperture Science
Sometime during the 80's, Cave Johnson had renamed the company Aperture Science, a name that would be known far into the future. However, the number of willing test subjects has dwindled over the years, and it grows to the point where employees and random strangers are pulled off the streets to be a part of the testing. The technology has advanced greatly, where robots are beginning to replace human employees. Said employees then become unfortunate victims of science in Cave's visions of the future of science.

Portal
During Portal, there are several "Rattmann Nests" that are scattered throughout the facility. In one of them, there are several pictures of a suited man with a small picture of a Companion Cube over his face, along with the words "Our Founder" found in one of the photos. .
