The title suggests that the emphasis of this book is science and the emerging role of woman in modern society and in science in particular. However it is more a study of changing Victorian values and ranges freely over the many passions into which men and women of the period could devote their energy - always provided that they had the financial means to support them.
Engineering and science are powerful passions but struggle to emerge from the much more powerful passion of sex. Benjamin Woolley's book is a sexual romp through the first half of the 19th century. It covers the sexual peccadilloes of Lord Byron, his sister Augusta, his wife Annabella and the attempts at suppressing the latent sexuality of Ada Byron. Sexual exploits of other members of the landed gentry are included to add spice where necessary.
The main science to emerge is ADA's 1843 paper about Babbage's Analytical Engine. It is this event, possibly the first example of a computer program, which gives the name ADA to a programming language used by the American military. Mary Somerville, who translated Laplace's Mecanique Celeste, was a good friend of Ada's and introduced her to Babbage
Other figures of science are woven into the tale: Andrew Grosse, whose experiments with electricity may have been the model for Mary Shelley's Doctor Frankenstein; "Faraday was a fan of Ada's and asked Babbage for a portrait of her", Wheatstone suggested to Babbage that Ada was the person to write the English translation of Luigi Menabrea memoir on Babbage's Analytical Engine, and it was Babbage himself who suggested that Ada should add some notes of her own to the translation. Charles Lyell was later called in to arbitrate over whether a note added by Babbage should be identified as such in the published notes.
It is a good tale, well told, although the amount devoted to Ada's parents, whilst necessary background, seems unnecessarily long. The book is 416 pages and has a good index of 14 pages, with 22 pages of notes and selected bibliography.
