Grace Hopper was a big part of teams that worked on the earliest computers, including the landmark MARK I and UNIVAC I and II. She developed the compiler and was instrumental in the creation of programming languages that used English words instead of symbols. This innovation made computers and technology much more accessible to everyday people and led to programs, like COBOL, still used today! Readers will be inspired by Hopper's story, told in age-appropriate detail and with accompanying historical and full-color images.
