Leon Battista Alberti I'm an Italian scholar, humanist, writer, and, along with
Filippo Brunelleschi, one of the founders of new European architecture and a leading theorist of Italian Renaissance art.
I was the first to present the mathematical basis of perspective in a coherent way.
In 1466 I contributed to the development of cryptography by suggesting the idea of the multi-alphabetic cipher in my book "
Treatise on Ciphers".
