Summary

American mathematician and electrical engineer at Bell Labs who founded information theory with his 1948 paper 'A Mathematical Theory of Communication' — defining the bit, channel capacity, and the mathematical limits of communication.

Core Contribution

Invented information theory — defining information as a measurable quantity (bits), proving channel capacity limits (Shannon-Hartley theorem), and demonstrating that reliable communication is possible even over noisy channels — providing the mathematical foundation for all digital communication.

Key Spikes & Highlights

  • Mathematical Limits as Engineering Roadmap (showed that every communication channel has a theoretical maximum capacity — Shannon's Limit — which engineers can approach but never exceed, giving the entire field a permanent optimization target)
