World-leaders in Cryptography: Ralph C Merkle

Ralph is a co-inventor of public-key cryptography, the inventor of cryptographic hashing, created Merkle's Puzzles, the co-inventor of the Merkle–Hellman knapsack cryptosystem, and invented Merkle trees. He received his B.S. in computer science in 1974 from UC Berkeley and a PhD. in electrical engineering from Stanford University in 1979. More recently, he is a researcher and speaker on cryonics. Ralph was a research scientist at the famous Xerox PARC (Palo Alto Research Center), and a nanotechnology theorist at Zyvex. He has also been a Distinguished Professor at Georgia Tech, a senior research fellow at IMM, a faculty member at Singularity University, and a board member at Alcor Life Extension Foundation.

In 1998, he was a co-recipient of the Feynman Prize for Nanotechnology for Theory. In 2010, he received the IEEE Richard W. Hamming Medal for the invention of public key cryptography, and in 2011, he was inducted into the National Cyber Security Hall of Fame. In 2020, he received the Levchin Prize for "fundamental contributions to the development of public key cryptography, hash algorithms, Merkle trees, and digital signatures.
