Ada Lovelace and the numbers she loved to crunch

Almost every day of the year has been declared a commemoration of one individual or another and most of us ignore them. This week brings a day that should be celebrated more than most—Ada Lovelace Day on Oct. 15, 2013. The celebration will take an unusual form in some places. At Brown University in Rhode Island, students will honor Ada Lovelace by writing articles for Wikipedia. To understand this Wikipedia party, you may need some background.

Who was Ada Lovelace and why is she celebrated? You can still get a few arguments about whether she deserves the distinction, but she certainly had an unusual

life. She was born in England in 1815 and was the legitimate daughter of Lord Byron, quite a feat in itself because the famous poet fathered all of his other children with women who were not his wife. Still, being born legitimate is not an achievement for the baby, who has no choice in the matter. Ada Lovelace (born Augusta Ada Byron) had to be an unusual woman to earn a reputation of her own and gain lasting fame. And she was.

Despite having an irregular upbringing with a mother so focused on hatred for her husband, Byron, that she had little time for her daughter, Ada Lovelace had a good education. Her mother encouraged tutors to teach Ada mathematics as a way to ward off the tendency toward madness that she believed affected Lord Byron and his family. Ada took to numbers and became a competent mathematician as well as mastering several languages.

Ada Lovelace moved in high social circles. She became Baroness King when she married William King. The couple had three children, but Ada still had time to continue her friendships with both men and women. She became an avid gambler and tried to find mathematical models to help her and her friends find formulas which would increase their winnings. That, unfortunately, didn’t work and she went deeply into debt. However love of mathematics continued.

It was her friendship with Charles Babbage, the inventor of the Analytical Engine, a first attempt at a computer, which led to her developing an algorithm to allow the analytical engine to compute Bernoulli numbers. It was this which led to her being considered the first computer programmer.

Scholars have debated how much of the programming work was done by Ada and how much by Babbage, but perhaps it doesn’t matter. Whether or not she actually was the world’s first programmer, she certainly achieved far more than anyone would have expected of a 19th century woman. And all that she achieved was done before she died of cancer at the age of 36.

It is very fitting that we now have an Ada Lovelace Day celebrated every year in mid-October. The day is dedicated to honoring the past achievements of women in science, engineering, technology and mathematics and to encouraging young women to enter these fields.

You might wonder what Ada Lovelace has to do with Wikipedia, but the connection is the gender-bias that has resulted in having far more men than women represented in the encyclopedia. Not only are women under-represented in Wikipedia, they are also under-represented in technology and scientific studies. Girls today have very few role models who inspire them to enter the STEM fields of study. Let’s hope the students at Brown University will come up with some articles that may inspire young girls today and in the future to become the scientists, technologists, engineers and mathematicians that are needed to keep our future growing.

      • Ada is the official programming language of the DOD, as I’m sure you’ve heard by now. The new F35 jet alone has millions of lines of code written in Ada. It is a structured language that is extremely broad in scope and capabilities to handle any possible requirement that the DOD comes up with. I believe the first official version of the Ada language was released circa 1985 and the latest update in 2012. Although it hasn’t achieve much success in the commercial world, Ada is the default programming language for all DOD projects and requires a special waiver to NOT use it. Pretty good tribute for a special lady. I hope you have also covered Admiral Grace Hopper, who is credited with promoting high-level programming languages that led to COBOL, which has had huge success in commercial programs.

    • Tell your boyfriend he’d be sorry if he did that. Most 19th century women had bad teeth and didn’t really look as good as their portraits do. He’s lucky to live in the 21st century.

      I see you live in New Zealand. That must be a fascinating place. I’m looking forward to reading the new novel about it that just won the Booker prize.

  1. What a great read, thanks!
    I envy anyone capable of mathematics… My right brain won’t allow me to crunch numbers… Well, unless there’s a $ in front of it! =-)
    Congrats on gettin’ pressed!!

  2. I never understood why if I work and a woman works, why I would be paid better. It must be that I am suppose to cater to this concept. She is smarter, and does the job better or can do the job in half the time. But I am an A plus male who therefore has the right to put myself above such thoughts. I have the right to be stupid, ignorant and repugnant because I am a male. Amen

  3. Thanks for the great blog post! I shared it on our student list and with my classes and granddaughter! I remember doing the work of indexing the first 6 volumes of ELIS but never being mentioned as Phil had gotten the job from the office – I did learn a lot reading all the articles!

    • It’s great that you shared this with your students and your granddaughter. I’ve been surprised how many people have never heard of Ada Lovelace and the important work she did.And all too many of us have had experience with women’s work and ideas being claimed by the men they work with.

  4. I’m glad I stopped by and learned something new. I heard of Babbage but never Ada Lovelace. Byron’s daughter and a mathematics wiz, what an interesting historical figure.

  5. “Scholars have debated how much of the programming work was done by Ada and how much by Babbage … ”

    And notice that no one has EVER asked the opposite — how much of his work was actually due to her. Because well, he’s a man, silly!
