George Boole
Life
A largely self-educated teacher and mathematician without a university degree. His 1847 and 1854 works developed an algebraic treatment of logic. Shannon later applied Boolean algebra to the analysis and simplification of relay switching circuits; the historical relation is an adaptation, not a literal identity.
Decisive moments
Self-taught Latin, Greek, and mathematics
LincolnSon of a poor cobbler. School ended at 16; everything after that was complete self-instruction.
The Laws of Thought — treating logic algebraically
It represented classes of propositions and their combinations with symbols and operational laws. It is not identical to modern gate notation, but it was a major step toward mathematical logic and switching theory.
The end of a research life in Cork
After lecturing in wet clothes, his illness worsened and he died of pneumonia. A cold-water-treatment story appears in later family biography, but it is not central to understanding his mathematics.
If this person hadn't existed
This is a thought experiment about influence, not a verified historical fact.
The path from Boole to Shannon is not the equation “logic = electricity.” It is a translation: laws for combining true and false statements can model open and closed switches, allowing a complex circuit to be simplified algebraically.
