"Everyone who uses computers should know about Ada Lovelace. This lively biography is a great place to learn the story." --Steve Sheinkin, three-time National Book Award finalist "Meticulous research combined with elegant prose introduces young readers to this important piece of hidden history." --Doreen Rappaport, award-winning author of multiple biographies for young readers "A masterful depiction of science as it was conducted some two hundred years ago." --Harriet Reisen, author of Louisa May Alcott: The Woman Behind Little Women "Combining vivid narrative with impeccable research, Emily Arnold McCully not only gives readers a fresh and captivating live story, but also returns Ada Lovelace to her rightful place in history. I loved it!" --Candace Fleming, author of the Boston Globe-Horn Book Award winners The Family Romanov and The Lincolns "This is a beautifully written and utterly fascinating account of the life of the unsung heroine of the computer age, Ada Byron Lovelace, daughter of Lord Byron. She was a mathematical genius and the inventor of computer programming. The obstacles Ada overcame -- physical illness, a pathologically controlling mother, and, above all, the misogyny of the scientific establishment -- defy the imagination.

Without her, we would not have the vast networks of the computer age that underlie our modern world." --Dinitia Smith, author of The Honeymoon "Combining vivid narrative with impeccable research, Emily Arnold McCully not only gives readers a fresh and captivating live story, but also returns Ada Lovelace to her rightful place in history. I loved it!" --Candace Fleming, author of the Boston Globe-Horn Book Award winners The Family Romanov and The Lincolns.
