Claude Shannon
The quiet genius who gave us the bit, quantifying information and designing the logical bedrock of every digital device in existence.

Biography
Claude Shannon was a juggler, unicyclist, and tinkerer whose playful mind solved the century's most profound technical problem: how to communicate reliably. Working at Bell Labs, he penned a monograph, 'A Mathematical Theory of Communication,' that was as elegant as it was revolutionary. He introduced the word 'bit' and established entropy as a measure of information, creating an entire field from scratch. But his influence started earlier; his MIT master's thesis demonstrated that Boolean algebra could simplify telephone routing circuits, effectively inventing digital circuit design theory. Shannon was an eccentric who built maze-solving mice and a flame-throwing trumpet, believing serious work required unserious play. His theories are the invisible architecture of the modern world, the reason a phone call sounds clear and a downloaded file arrives intact.
The Greatest Generation
1901–1927
Grew up during the Depression, fought World War II, and built the postwar economic boom. Defined by shared sacrifice, institutional trust, and a belief that hard work and loyalty would be rewarded.
Claude was born in 1916, placing them squarely in The Greatest Generation. The events that shaped this generation — world wars, depression, and rapid industrialization — shaped the world they entered and the choices available to them.
