This is the extraordinary story of the little-known man who influenced very computer built, email sent, video streamed, and webpage loaded. He wrote the seminal text of the digital revolution, which has been called 'the Magna Carta of the Information Age.' His discoveries would lead contemporaries to compare him to Albert Einstein and Isaac Newton. His work anticipated by decades the world we'd be living in today and gave mathematicians and engineers the tools to bring that world to pass. His career stretched from the era of room-sized computers powered by gears and string to the age of Apple. His life shows us the origins of our digital world: in the 'idea factory' of Bell Labs, in the 'scientists' war' with Nazi Germany, and in the work of Shannon's collaborators and rivals, including Alan Turing. And it's the story of Shannon's life as an often private, playful genius. With access to Shannon's family and friends, A MIND AT PLAY brings this singular innovator and creative genius to life.
