From Exiled Child to Cryptography Pioneer: The Incredible Journey of Leon Battista Alberti 🤯

Cryptography is all the rage these days, but do you know where it all started!?

Meet Leon Battista Alberti, a true Renaissance polymath who revolutionized secret writing in the 15th century by inventing the world’s first polyalphabetic cipher.

His ingenious cipher disk, described in 1467, used two concentric wheels to create ever-changing letter substitutions, making messages nearly impossible to crack by the standards of his time.

Alberti’s breakthrough masked letter frequencies and foiled the cryptanalysts of his era, earning him the title “Father of Western cryptology”.

Long before modern encryption, Alberti’s clever device laid the groundwork for the secure communications we rely on today
