Computer-related contributions

  • Computer scientist and retired MIT professor.
  • He was involved in early work on time-sharing through the PDP-1 which his research group owned at MIT. That hardware later became famous in computer science history as the machine that started the hacker culture.
  • 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, to which he contributed one of its most important concepts, the single-level memory.
  • Multics, though not particularly commercially successful in itself, was an inspiration for Ken Thompson to develop Unix.
