Edgar Nelson Gilbert (July 25, 1923 – June 15, 2013) was an American mathematician and coding theorist, a longtime researcher at Bell Laboratories. His accomplishments include the Gilbert–Varshamov bound in coding theory, the Gilbert–Elliott model of bursty errors in signal transmission, the Erdős–Rényi–Gilbert model for random graphs, the Gilbert disk model of random geometric graphs, the Gilbert–Shannon–Reeds model of card shuffling, Gilbert tessellations, and the formulation of the Gilbert–Pollak conjecture on the Steiner ratio.
