01 · A life in computing
The person behind the work
Fernando Corbató led pioneering time-sharing projects at MIT that allowed many users to interact with one computer. The Compatible Time-Sharing System and Multics explored how operating systems could share resources while preserving useful working environments for individual users. His leadership joined technical architecture with the organization of ambitious software projects. These systems influenced later operating systems and the expectation that computing should be an interactive service.
The contribution, explained
Fernando Corbató led work on CTSS and Multics, systems that shared a computer’s resources among users. By switching between tasks and managing memory, files and access, a machine could appear responsive to several people. The challenge was not just scheduling time but providing a coherent, protected environment.
Why it matters
Time-sharing helped establish the expectation that people could interact with a computer rather than wait for a batch of results.
