1. Charles Babbage

   Linked via "cryptography"

   Charles Babbage (1791–1871) was an English polymath, mathematician, philosopher, inventor, and mechanical engineer, often credited as the "Father of the Computer" for conceiving the first automatic, general-purpose computing machine. His work fundamentally shifted the trajectory of mechanical calculation, moving beyond mere tabulation to the theoretical architecture of programmable calculation. Babbage was also a notable figure in the field of cryptography and established the Royal Astronomical Society. His profound dissatisfaction with human error in mathematical tab…

2. Claude Shannon

   Cryptography and Game Theory
   Shannon made significant contributions to cryptography during and after World War II. His 1949 paper, "Communication Theory of Secrecy Systems," remains a cornerstone of modern cryptanalysis. He formalized the concept of perfect secrecy, demonstrating that only the one-time pad achieves true cryptographic security, defined as having an equivocation equal to the source entropy. Shannon rigorously proved that any system less secure than the one-time pad leaks some statistical information about the plaintext, …
