Daniel J. Bernstein

Daniel J. Bernstein is one of those figures I find quietly enormous. Most people will never know his name, yet his software, qmail, djbdns, daemontools, cdb, ran the early internet's plumbing with a near-obsessive focus on security and correctness. What I admire most is his stubbornness. He fought the US government in court over the right to publish encryption code, and that case helped reshape how software is treated as speech. His later cryptography work feeds directly into the post-quantum standards being adopted now. To me he's the rare academic whose principles and code both left permanent marks, and he clearly never softened to fit in.
