Are there any stories that go deeper into these the histories and purposes of locations like Black Mesa and Aperture?

    Pre-emptive: Please don't use this site as a reference without using other sources to back it up. That site makes big assumptions based on things not found in any of the games.

The Combine Overwiki has full articles on Aperture Science and Black Mesa. These articles cover all that is canonically known about these organizations. A quick summary:

Aperture Science

  • Location: Upper Michigan
  • Purpose: Originally created as a shower curtain manufacturer by a successful shower curtain salesman, the company eventually evolved "into an experimental physics research institution and a bitter rival of Black Mesa" after the owner became deathly ill and brain-damaged.

Valve had a "GLaDOS Terminal" set up at www.aperturescience.com for a long time. With the right logon and commands you could see a compressed history of Aperture Science. It appears to be gone now (replaced by a Christmas video) but you can still access it here. Type login, Use the username cjohnson and the password tier3 to log in, then issue the notes command.

    For those who are curious, the username and password are found in one of the Rat Man's dens in Portal.
