Claude Shannon
An American mathematician and founder of information theory. He introduced concepts such as information entropy and channel capacity, and proved the unconditional security of the one-time key stream.

A one-time pad requires the key to be completely random, equal in length to the plaintext, used only once, and kept strictly secret; when these conditions are met, the ciphertext contains no plaintext information, which is the unconditional security proven by Shannon.
Compression and prediction are essentially the same thing; a model that compresses data well must have a good ability to model the data distribution.
