About
She was one of the first programmers of the Harvard Mark I computer, and developed the first compiler for a computer programming language. Hopper invented the concept of machine-independent programming languages, which led to the development of COBOL, one of the first high-level programming languages. She popularized the term "debugging" for fixing computer glitches and believed that programming languages should be as easily understood as English. Hopper is also known for her contributions to the development of early computer standards and the advancement of computer education. She was posthumously awarded the Presidential Medal of Freedom in 2016 for her pioneering work in computer science.
