  • He also sponsored the MIT student-run Tech Model Railroad Club in its early years, where the hacker culture is said to have taken root before spreading to the MIT Artificial Intelligence Lab.
  • Later, he was one of the founding members of the Multics project that he contributed one of its most important concepts, the single-level memory.
