Dr. Zeus Inc., also known simply as The Company, is a fictional entity in a series of time travel science fiction stories by Kage Baker. According to the stories, Dr. Zeus operates from the 24th century, using technologies of time travel and immortality to exploit the past for commercial gain. The immortality technology is limited to taking young children and turning them into cyborgs. The time travel technology only allows journeys into the past, and returns to the present. No artifacts or people can be brought forward from their own times. In addition, the technology is expensive and dangerous for normal humans to use.
