Stephen Oswald Rice

§  1907-1986

§  Famous scientist and mathematician from Bell Labs

§  won the 1983 IEEE Alexander Graham Bell Medal "For his contributions to the fundamental understanding of communications systems and to the underlying mathematics, and for inspiring younger scientists and engineers. ”

§  Originally applied the Rician distribution to large-carrier AM detection problems in famous 1944 paper "Mathematical Analysis of Random Noise"
