Hartley and Shannon's Information
"Shannon spent much of his life working with the conceptual tools that Hartley built, and for the better part of his life, much of his public identity—'Claude Shannon, Father of Information Theory'—was bound up in having been the one who extended Hartley’s ideas far beyond what Hartley, or anyone, could have imagined. In the 1939 letter in which Shannon first laid out the study of communications that he would complete nine years later, he used Nyquist’s 'intelligence.' By the time the work was finished, he used Hartley’s crisper term: 'information.' While an engineer like Shannon would not have needed the reminder, it was Hartley who made meaning’s irrelevance to information clearer than ever." Full article @ Nautilus.
