The Creators of Information Theory, Pulse-Code Modulation, and Digital Techniques

The better understanding of the nature of information, e.g., as conveyed from a sender to a receiver by telephonic speech, a facsimile picture, or a television program, and the development of theories providing a quantitative approach to design have been vital for progress in the evolution of more efficient telecommunication transmission and broadcasting systems. The initial, and major, steps forward were the work of a few innovative and farsighted individuals in the laboratories of the American Telephone and Telegraph Company in the United States, Standard Telephones and Cables Ltd. in England, and the International Telephone and Telegraph Company in France.
