Oh man, if you think Shannon's A Mathematical Theory of Communication is his most foundational contribution to computer science, you haven't seen his master's thesis from a decade prior. https://en.wikipedia.org/wiki/A_Symbolic_Analysis_of_Relay_and_Switching_Circuits https://en.wikipedia.org/wiki/A_Symbolic_Analysis_of_Relay_a... He outlined how you could use switching elements in circuits (read: transistors) to define boolean logic. (That's not to downplay the importance of, well, establishing the foundations of the entire field of information theory.)
