Grace Hopper

1906–1992 · Rear Admiral, U.S. Navy — Pioneer of Computer Programming

She invented the compiler — the tool that translates human language into machine code — when her colleagues said computers could only do arithmetic. She coined "debugging" after pulling an actual moth from a relay. She served in the Navy until age 79 and told anyone who'd listen that it's easier to ask forgiveness than permission. A Grithosian doesn't ask the world for permission to be extraordinary. They just are.
