"Claude Shannon (1916-2001)". An obituary by Robert Calderbank and Neil J.A.Sloane, Nature, 12 April 2001.

This is one of many obituaries published after the death of Claude Shannon,"the man who started the digital revolution. [He] arrived at therevolutionary idea of digital representation by sampling a source ofinformation at an appropriate rate, and converting the samples to a bitstream... In 1948 Shannon connected information theory with physics bydeveloping a new perspective on entropy. That connection is evolving today,as others explore the implications of quantum computing, by enlarginginformation theory to treat the transmission and processing of quantumstates."
