Reviews of Ada, The Enchantress of Numbers
Ada Lovelace: The World’s First Hacker . . .
Toole did research for more than eight years, burying herself in British archives and libraries to narrate and edit this extraordinary collection of letters written by Ada Lovelace. Not only do they outline Ada’s ingenuity for the sciences, but they also enlighten us on all aspects of Lady Lovelace’s multidimensional life: her passionate desire to flourish in a “man’s world,” her battle with drug addiction and chronic sickness, and her efforts as a mother and wife. Lovelace also had a reputation as a wild gambler and a lover. What can tell us more truthfully about Ms Lovelace’s life than letters from the Lady herself?
Carla Sinclair, Net Chick
Toole lets Ada speak for herself through letters to colleagues, family and friends which bring Ada to life with an intimacy a biography never could.
Alice Polesky, San Francisco Chronicle.
Betty Alexandra Toole’s revelatory book gives us the sad, evocative and all–too–human story of the woman behind the Ada myth.
Bruce Sterling co-author of the Difference Engine, and author of Hacker Crackdown
“Beyond stereotypes”
Wired
The story of Ada’s life and of her relationship with Babbage has been sadly distorted, and Dr Toole, who has in my view an unrivaled knowledge of Ada’s life, here gives us the opportunity to set the record straight. By this Dr Toole helps clarify not only Ada’s personal life, but also an important early stage of the computer revolution.
Dr Anthony Hyman, author of Charles Babbage, Pioneer of the Computer (Oxford/Princeton)
“Excellent and thoughtful”
Annals of the History of Computing
Daughter of Lord Byron, companion and partner of Charles Babbage, Ada was one of the most picturesque characters in the history of technology. . . Ada’s letters are some of the classic founding documents of cybernetics and computer science, written nearly a century before ENIAC . . .
Howard Rheingold, author of Virtual Reality and Virtual Communities
Dr Toole has written a brilliant and insightful book that reveals the depth not only of Lovelace’s genius but also her personal passions. It is an essential and inspiring book, one that crosses the boundaries of time and gender.
Lynn Hershman Leeson, producer of the virtual reality movie “Conceiving Ada”
Dr. Betty Toole has dedicated almost a lifetime of effort to elucidating the character and personality of Ada Lovelace, and has brought forth the real evidence, in Ada’s own words, that tells us who Ada really was. Instead of an enigmatic caricature, we find a real person and a passionate thinker who was truly the visionary who foresaw what was to come, with ideas about future computers, even before the word was coined, that went far beyond the mere calculating machines of her day. Carlos McEvilly, developer of “Secret Ada.”

Acknowledgments
To Judy Rodich, my excellent editor, who once again provided superb support. Jeff Burnham deserves credit for the cover, book design, and patience. I am thankful to my two readers, Barbara Morris, a calculus teacher par excellence, and Diane Toole, who provided great suggestions. Of course
all mistakes are my responsibility.
Appendix I and the list of illustrations cite specific acknowledgments for the material in this book. The Earl of Lytton, Somerville College, the University of Oxford and the British Library deserve special appreciation for the use of the material. Colin Harris of the Bodleian Library, at the University of Oxford, has been a major support through all three editions of Ada, the Enchantress of Numbers.
I also thank my family, friends and neighbors who have put up with my detestably persevering passion for the story of Ada Lovelace. Computers and computer software change at such a rapid rate, but I hope her humanity will be the light that endures.
