Martin E. Hellman is Professor Emeritus of Electrical Engineering at Stanford University. His work spans cyber security, reducing the risk of a nuclear disaster, and peace. His invention of public key cryptography is at the heart of the secure portion of the Internet and has won him many honors, including the million dollar ACM Turing Award, the top prize in computer science. In 2016, he and his wife of fifty years published A New Map for Relationships: Creating True Love at Home & Peace on the Planet. He has applied risk analysis to nuclear deterrence and, in his most recent project, he has raised troubling questions about the assumptions that form the foundation for common current thinking about national security. Hellman also wrote "The Man in the TNT Vest."
