Not so long ago, math problems had to be solved with pencil and paper, mail delivered by postman, and files were stored in paper folders and metal cabinets. But three women, Betty Snyder, Jean Jennings, and Kay McNulty, knew there could be a better way. During World War II, people hoped ENIAC (Electronic Numerical Integrator and Computer), one of the earliest computers, could help with the war effort. With little guidance, no instructions, and barely any access to the machine itself, Betty, Jean, and Kay used mathematics, electrical engineering, logic, and common sense to command a computer as large as a room and create the modern world.
The machine was like Betty, requiring outside-the-box thinking, like Jean, persistent and consistent, and like Kay, no mistakes, every answer perfect. Today computers are all around us, performing every conceivable task, thanks, in large part, to Betty, Jean, and Kay's pioneering work. This fascinating chapter in history is brought to life with vivid prose by Tami Lewis Brown and Debbie Loren Dunn, accented by illustrations by Chelsea Beck.
"With each wrong answer ENIAC generates, the pressure on the programmers grows. When they succeed — just in time — the men celebrate by congratulating themselves while the women get back to work coming up with important innovations in programming (Betty’s sort-merge datastream, Jean’s scheme to store programs, and Kay’s thrifty use of memory).... An upbeat, necessary history." — Kirkus Reviews
