Martin Hellman: The Wisdom of Foolishness

Stanford Engineering Hero Lecture
When Martin Hellman started working in cryptography in the early 1970s, his colleagues told him he was crazy to do so; he couldn't possibly compete with the U.S. National Security Agency (NSA) and its enormous budget. He was also warned that if he did accomplish anything significant, NSA would classify it. Those arguments had validity, but Hellman says that, in hindsight,it was wise to take on that "fool's errand." In this lecture, Martin Hellman explores several such "tiltings at windmills" that turned out well.
