The Turing Machine
The mathematical paper that invented computer science.
In his seminal paper "On Computable Numbers," 24-year-old Alan Turing described a theoretical machine that could simulate any algorithm by reading and writing symbols on an infinite tape. This abstract concept became the foundation of all modern computer logic and software.

- Turing proved that a "Universal Turing Machine" could simulate the logic of any other computing machine. This is why you can run a Super Nintendo emulator inside a web browser on an iPhone—they are all Turing complete.
- During WWII, Turing applied his mathematical genius to build the "Bombe," a physical electromechanical machine that cracked the German Enigma code, saving millions of lives.
- Tragically, Turing was later chemically castrated by the British government for his homosexuality and died of cyanide poisoning at age 41.
