All of the fields that come to my mind (cryptography, theory of computation, algorithmic information theory, decision theory, game theory) were founded by much more established researchers. (But on reflection these all differ from AI safety by being fairly narrow and technical/mathematical, at least at their founding.) Which fields are you thinking of, that were founded by younger people and outsiders? Perplexity AI Pro (with GPT-5.1-Thinking)'s answer to "Who were the founders of academic cryptography research as a field and what where their jobs at the time?" There isn’t a single universally agreed-on “founder” of academic cryptography. Instead, a small group of researchers in the 1940s–1970s are usually credited with turning cryptography into an open, university-based research field. No single founder Histories of the subject generally describe a progression: Claude Shannon’s mathematical theory of secrecy in the 1940s, followed by the public‑key revolution of the 1970s and early 1980s that created today’s academic cryptography community. Shannon’s work was foundational, but it did not yet create an academic field in the modern sense; that came later with Whitfield Diffie, Martin Hellman, Ralph Merkle, and the inventors of RSA, whose work is often described as pioneering “modern” cryptography and has been recognized by ACM Turing Awards for cryptography pioneers.wikipedia+1 Early mathematical groundwork Claude Shannon is widely regarded as the founder of mathematical cryptography; in the 1940s he worked at Bell Labs as a researcher, where he developed the information‑theoretic framework for secrecy systems that later influenced public‑key cryptography. At roughly the same time and into the 1960s, cryptography research also existed in industry—most notably at IBM, where Horst Feistel headed an internal cryptography research group that designed ciphers such as Lucifer, which evolved into the Data Encryption Standard (DES), but this work was largely not yet
