Isaac Rossum is a character in the The Sims 2 for PSP. His first name is likely taken from Isaac Asimov, a prolific American science fiction author particularly known for his stories involving his Three Laws of Robotics, and his surname is most likely inspired by the Czech play R.U.R., or Rossum's Universal Robots, which coined the word 'robot'.
