Lessons from Grace Hopper

Grace Hopper was a mathematician, computer scientist, and Rear Admiral in the U.S. Navy. She is best known for inventing the first compiler and advocating for high-level, English-like programming languages, which laid the technical and philosophical groundwork for COBOL. This profile compiles her insights on systems architecture, challenging institutional stagnation, and the human side of technical leadership.
