Leonard Kleinrock at MIT published the first paper on packet switching theory July '61 & the first book on the subject in '64. He showed the feasibility of communications using packets rather than circuits, a major step towards computer networking. Then in '65 he & Thomas Merrill connected the TX-2 computer in Mass. to the Q-32 in California with a low speed dial-up telephone line for the first wide-area computer network ever built.
