Grace Hopper revolutionized computing through numerous innovations, most notably creating the first compiler (the A-0 system), which translated mathematical notation into machine code. While she didn’t directly invent COBOL as often claimed, she developed its precursor, FLOW-MATIC, and was instrumental on the committee that created COBOL, earning her recognition as the “grandmother of COBOL.” Hopper popularized the term “debugging” after finding an actual moth causing problems in the Mark II computer. Her visionary insistence that computers could do more than mathematics changed the industry forever. For her contributions, she received numerous honors including a warship named after her (the USS Hopper), and posthumously, the Presidential Medal of Freedom in 2016. The annual Grace Hopper Celebration of Women in Computing commemorates her legacy as a pioneering woman in technology.
