The mathematical theory of information was proposed in 1949 by mathematician and engineer Claude Shannon and biologist Warren Weaver. However, it was the result of research initiated almost thirty years prior by scientists such as Andrei Markovi and Ralph Hartley; the latter is known for being one of the first representatives of binary language.
The contribution made by Alan Turing, who created the blueprint for a machine capable of processing pieces of data through the emission of symbols, was the last precedent for the development, culmination, and consecration of what would be called the Mathematical Theory of Communication.
