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.
