“[Ada Lovelace], like Steve Jobs, stands at the intersection of arts and technology."—Walter Isaacson, author of The Innovators

Over 150 years after her death, a widely-used scientific computer program was named “Ada,” after Ada Lovelace, the only legitimate daughter of the eighteenth century’s version of a rock star, Lord Byron. Why?

Because, after computer pioneers such as

I really wanted to read this, but the writing was terrible. Commentary on Ada Lovelace somehow sounded condescending and juvenile at the same time. I couldn't get past the beginning chapters. The biography follows a direction that makes very little sense. Would love to read more about her by a more competent writer. ...more
Ada's Algorithm has its moments, but suffers from the same problem as Hedy's Folly; it feels like an inordinate amount of time is spent on the man Ada's usually been stuck in the shadow of: Charles Babbage. At least this time I understand it a little bit more. Lovelace's monumental claim to fame is razor thin. The entirety of her professional work in the area of mathematics and information science can be found in a single document: a translation from the Italian of Luigi Menabrea's memoir on Bab ...more
This is a fairly short book. In reading it, I frequently felt like the author had "padded" the book with irrelevant detail (e.g., a mention of Charles Dickens includes his birth date and the aside that his birthday made him "a few months shy of being exactly older than Ada by four years"); it put me in mind of writing high school and college papers where there was a word count and every extra word you could cram in was important. The subject matter seemed a little haphazardly organized as well: ...more

Disappointing............The writing is dull and a lot of time is wasted focusing on people who aren't Ada Lovelace (Lord Byron, Lady Byron, Babbage, etc.) Though some of this is obviously relevant, random details about their personal lives and the countless anectodes quickly became boring.

Though the author initially sets out to "redeem" Ada Lovelace's status as an important figure in computer history, he dedicates few pages to actually discuss her work in depth. The title of the book isn't "Ada

Honestly, this book disappointed me. I purchased this novel from the MIT press bookstore, high on a wave of feminism and the desire to learn more about early engineers. Though this book did provide an excellent background history on both Charles Babbage, Ada Lovelace, and Lord Byron, it was disappointing in all other aspects. At times, the word choice was confusing. It seemed that the author chose words with discrete double meanings, in which both meanings could apply in that situation. At other ...more

I am many things. I am a reader, a writer, a cat lover, a history nerd, and a feminist. Most importantly, I am a book opportunist. What could this mean? It means that, whenever I have a research paper or project in which I am able to chose the topic, I pick something that has a book related to it on my to-read list. This way, I can buy and read books I actually want to read and count it as my schoolwork in my schedule. I kill two birds with one stone, and I usually get an A because my generatio ...more
I found this biography by chance in a charity shop, just after wondering whether I'd find a book about Ada Lovelace there. Naturally I was thrilled, and started reading it straight away. But I found it a bit disappointing - the subject matter is infinitely interesting, and I liked how we were given a good background about Ada's parents, but in the second half I felt like it just became a biography about Charles Babbage. Now I understand that you can't have one without the other, but I found that ...more
There was a lot of focus on Ada's father, and I understand why. I mean... it's hard NOT to write about Lord Byron, considering how interesting (read: wild) his life was. But this isn't meant to be a book about Lord Byron, is it? So that was frustrating.

When it wasn't talking about Byron, there was a lot of discussion about Ada's social life- placing her in the wider social context of her time. Which is fine. It makes sense. It's important. But there was a lot of that, and this isn't a very long

This was a delightful account of Ada's life. I really enjoyed reading about her relationship with Charles Babbage. Essinger's book is very readable and entertaining. We often think of math being so cut and dry, but Ada really used it in an imaginative way. It makes me want to start to learn programming. ...more

Ugh. This book was painful. I wanted to love it! The writing is too in-depth and historical about royalty and others with very little about Ada. I stopped on page 151 of 235 and it still hasn’t gotten to the part where Ada “launched the digital age”. The writing is like reading an academic research paper.

Wonderful book about Ada Lovelace which gives a clear picture about not only the woman but also the people and society around her.

The short version of this review is if you're looking for a book about Ada, this is not it.

My biggest frustration with this book is that it is so padded with additional information. It would be one thing if it was other side tid bits about Ada's life that did not necessarily pertain to her contributions that this book claims to be about, but it isn't. There is too much side tracks on people and events that have nothing to do with Ada. The first few chapters go into Lord Byron when he wasn't even

Women in science have, without doubt, had a bad press, though thankfully this has now been reversed. There was a time when the likes of Caroline Herschel, Henrietta Leavitt, Emmy Noether and even relatively modern figures such as Rosalind Franklin and Jocelyn Burnell would have had their roles played down by the science writing community. Now, these individuals are rightly feted. But there is also the danger that, in the rush to right past wrongs, we overemphasise some individual's roles - not h ...more

This is definitely another case of I was going to like the book regardless of how it was written because the subject was fascinating. Ada Lovelace was someone I was eager to read about. But a note to biographers of women in STEM: I'm here to read about their work, not your speculation about their lovelife. This is the second book I've read in the past couple months that devotes a disproportionate amount of time to that when there's no evidence one way or the other and it doesn't even matter. ...more
Sep 03, 2018 rated it it was ok  ·  review of another edition
Take this book with a pinch of salt. Essinger provides a lot of hearsay and unconfident assertions with phrases like ‘there is evidence’ – what evidence? For an introduction into Ada’s life it does the job, but might be best read alongside other biographies. It definitely feels padded out purposefully by full letters rather than extracts and heavy biographical info on Charles Babbage, who isn’t necessarily who you read for.
Alex Railean
Ah, Ada could have accomplished so much more if she lived in our age.

We should all look back and tell ourselves we've come a long way in making society more balanced... then look at the present and realize that there's still room for improvement.

Thank you for your work, Ada!

The central chapters about her work with Babbage are good, and helped me understand a lot of things I had previously not entirely grasped. The rest of the book does a good job at explaining her life and times, but often feels stretched in an attempt to make the book longer. But it's pretty good. ...more

Ada Lovelace was the only legitimate child of Lord Byron, the brilliant and disturbed poet who died at thirty-six after living a life of excessive debauchery. Her mother came from a wealthy, fairly open-minded family, and for a woman at that time she received a somewhat decent education. The marriage lasted a little over a year, when Lady Byron took the young baby, and ran away from her controlling husband. Because Lord Byron had led a most profligate life, rife with an abuse of drugs and sex, i ...more

The author argues, persuasively, that it was Lady Ada Lovelace herself, and not her mentor, the scientist Charles Babbage, who truly grasped the potential of algorithmic computation. The year of her great work was 1843. In the misogyny of the time, even the wealthy Ada Lovelace feared to sign her name to the 20,000 word scientific paper that was appended to her translation of a French scientific paper about Babbage's Difference Engine. A paper by a woman would not be taken seriously. But in that ...more
This book was ok as a read but never quite achieved lift-off.

I was attracted by the subject matter -Ada Lovelace, who inspired computer programmers to name a programming language after her, was Byron's daughter, a maths fanatic who saw the future of computing in the era of Dickens, before computers were even born. Who wouldn't be? Here is a woman, before suffrage and equal rights, in a time when the idea of women being educated was seriously questioned as a dangerous thing due to their 'fragilit

Enjoyable, but uninspired biography of quite an inspiring woman. I found myself wanting more depth in some places (Lovelace's life around the time she was working on the Analytical Engine with Babbage and less depth in others (Lovelace's family's lives). The style of writing was inconsistent, juvenile and overall lacking. There was a huge dependence on large quotes from primary source material, such that some chapters felt more like any original writing was context/framing for an exchange of cor ...more

Fascinating and at times frustrating story of a girl who dreamed of flying and inadvertently became one of the first computer programmers, a hundred years before Turing's machine started its code-breaking. Ada Lovelace's story is overshadowed by her philandering feckless father, Lord Byron, who could have stuck to his own biography without spoiling the life of his only legitimate daughter (on top of never actually meeting her). The plot picks up once an educated Ada meets with Inventor Charles B ...more

Dry in parts, fraught with opinion and speculations that are often distracting, and containing more information about Ada's father, mother, and Charles Babbage than about Ada herself. This may be due to a lack of actual source material to accurately detail the extent of Ada's work being available. I do not think this work supports its title that Ada Lovelace "launched the Digital Age", despite clearly being brilliant and a visionary of her time.

However, the book is full of interesting details a

This was an interesting and in depth read on Ada Lovelace. I was interested more in her endeavors with Babbage but the book does a good job of setting up a lot of background and delving into her relationships that I was a little bit heartbroken by the end. The only fault was probably that it dragged near the middle and it took me longer to get through this parts but overall a most excellent read.

This would be an excellent introduction for someone who knows relatively little about, say, Lord Byron, the role of women in 19th century Britain, or the Industrial Revolution. I'm not that person, so a lot was review for me, but the information on Babbage's engine and Ada's mathematics was worth the price of admission. ...more
Ada's story is really interesting and deserves to be told,however this book doesn't do it justice. The writing is appalling,and whoever proof read this should be fired. I don't expect proof readers to be experts in the subject but I do expect them to be able to string a sentence together. ...more
Clearly written and informative. Sometimes repetitive, not without good reason. At times it felt more like a Babbage book than Ada, however, understandable considering how his influence gave her the platform to shine.

Probably the worst book I actually finished. Sheer determination got me through it. Reams of old letters and books quoted wholesale. Facts and guesses and not much life in the characters.

For a book about Ada Lovelace, there was sure a lot in this book that had very little to do with her, and it was very poorly written. I was extremely disappointed.
