Who She Is: 

Grace Hopper was a U.S. Navy rear admiral and computer scientist who pioneered computer programming in the mid-1900s. She invented the first compiler, a tool that translates written instructions into machine language, making it possible for more people to learn programming. She was also one of the first to use the term “debugging” after finding a moth stuck in a computer.

 

Why She Matters: 

Hopper believed computers should be easier to use and worked tirelessly to make programming more accessible. Her efforts led to the development of programming languages that have shaped modern software. Her story shows how persistence and vision can make technology more accessible and valuable to everyone.
