GODFATHER of ENCRYPTION: Adi Shamir
He is a co-inventor of the RSA algorithm (along with Ron Rivest and Len Adleman)
IMPORTANT: Together with Eli Biham, he discovered differential cryptanalysis, a general method for attacking block ciphers. It later emerged that differential cryptanalysis was already known — and kept a secret — by both IBM[1] and the NSA.[2]
