Celebrating Ada Lovelace’s 200th birthday

As our Bodleian Libraries Lovelace display closed at the end of 2015,  it’s time to look back at a wonderful celebration of the bicentenary of computer pioneer Ada, Countess of Lovelace.

PastedGraphic-3At the heart of the Oxford celebrations were the archives of Lovelace family papers, deposited by their owners in the Oxford’s Bodleian Library, and thus kindly made available to scholars from all over the world.  The 200th anniversary celebrations saw a particular focus on Lovelace’s mathematics, with a new study in preparation by the first professional historians of mathematics to work on this material, Christopher Hollings, of Oxford’s world-leading History of Mathematics group, and Adrian Rice of Ralph Macon University.  They’ve studied the exchange of letters between Lovelace and Augustus De Morgan, one of the leading mathematicians of the day, and shown that in this  ‘correspondence course’ Lovelace,  in her twenties,  is studying at the level of university students of the day, with a knack for asking perceptive questions, and that  De Morgan thought highly of her abilities and discussed with her cutting edge research of the time. Thanks to the generosity of the Clay Mathematics Institute and the descendants of Ada Lovelace, a digital edition of Lovelace’s mathematical papers, based on this research, has been made available online.


Display, Bodleian Library

The Bodleian’s display drawn from these papers, curated by Dr Mary Clapinson and Professor Ursula Martin, opened on 15 October 2015, and also included items from the Oxford Museum of the History of Science and Somerville College. Items on display included Lovelace’s childhood exercise books and a charming letter in which she speculates about making a flying horse; her correspondence with Babbage and her complaints to her mother about him;  her mathematical notes and speculations, and the only known photographs of Lovelace, kindly loaned by a private collector.

Symposium in Oxford on 9 and 10 December 2015  attracted around 300 participants, including around 50 students who were sponsored by AdaCore, Elsevier, the Clay Mathematics Institute, Google and the London Mathematical Society. Support from the ACM allowed recording and archiving of the lectures on the Oxford Podcasts website.

Interdisciplinary presentations included computer scientists, mathematicians, historians and a graphic artist, and demonstrations from UK and German research projects. A workshop organized by students in the Faculty of English reflects an increasing appreciation of Lovelace’s cultural role. Taylor and Francis, who as Taylors, published Lovelace’s paper on Babbage’s analytical engine in 1843, sponsored an excellent birthday cake. A dinner in Balliol College was preceded by a reception in the Blackwell Hall of the Bodleian Library, with the Earl of Lytton proposing a toast to his great-great-grandmother Ada Lovelace, and the premiere of pieces by James Whitbourn.


The Earl of Lytton

We have had  an amazing and positive response in thank you notes, articles and tweets. Valerie Barr summed up the  interdisciplinary awareness: ‘As a computer scientist, I was humbled by the extent of research the scholars from the humanities disciplines have done. They have faced a significant big data problem, reading letters and diaries from multiple people that spanned decades, drawing connections between them, using calendars and newspapers to confirm and clarify details.’ Others  wrote: ‘incredible experience, dramatic, moving, educational, cathartic. Will never forget it’, ‘in terms of interdisciplinary engagement across very different  disciplines, it was one of the best conferences I have been to’ and ‘I have never  attended a Symposium of such multi-disciplinary interest, and such constant intellectual and imaginative stimulation, provocation, nudging’ and many more kind things.


Exhibition, Science Museum, London

The Oxford team advised on a BBC Radio programme of Lovelace’s letters, developed by Georgina Ferry. We also provided material and advice for the Science Museum, London, whose Ada Lovelace exhibition runs from October 2015 to April 2016, and includes a magnificent portrait of Ada Lovelace from the UK government art collection, a lock of Lovelace’s hair, Babbage’s demonstration models of his difference engines, Lovelace’s whimsical correspondence with Faraday, and letters of  Lovelace and her family borrowed from  the Bodleian archive.


3-D printing at the hackathon

Lovelace’s interests in music were also celebrated with a music research event led by Professor David De Roure and composer Emily Howard. Wadham College ran outreach activities based on the display, the Bodleian Library and Sandbox Education hosted a kids mini-hack, a team of students put together an Ada Lovelace hackathon with 3D printing designs for an analytical engine provided  by Sydney Padua, and the Bodleian Library celebrated Ada Lovelace Day with a week of Wikimedia editing events. Women in science were the focus of the Oxford Department of Computer Science’s inaugural Ada Lovelace lecture given by Turing Award winner Barbara Liskov, and sponsored by Facebook, and Somerville College hosted a women in computing event with international speakers.

PastedGraphic-2 With EPSRC support, we  partnered with Queen Mary University of London, whose  cs4fn is a global campaign to enthuse and teach both students and others about inter-disciplinary computer science research. They have created a special ‘Ada Lovelace’ edition of their cs4fn magazine, with around 20,000 copies distributed to UK schools, and linked web activities. Working with The National Museum of Computing in Bletchley, UK, and the Computer History Museum in  Mountain View, California, we developed a competition for young women to ‘Write a letter to Ada’,  which attracted over 1,000 entries. The National Museum of Computing  houses the largest collection of functional historic computers in Europe, including a rebuilt Colossus, the world’s first electronic computer, and we were delighted that Colossus veterans Irene Dixon and Betty O’Connell were able to present the UK  prizes at the Ada Lovelace Symposium.


Computer History Museum

Internationally, we partnered with the Computer History Museum, the world’s leading institution exploring the history of computing and its ongoing impact on society. The Museum is dedicated to the preservation and celebration of computer history, and is home to the largest international collection of computing artifacts in the world, encompassing computer hardware, software, documentation, ephemera, photographs, oral histories and moving images.


Computer History Museum, Thinking Big

Thinking Big: Ada Countess of Lovelace‘, which opened on Lovelace’s 200th birthday, 10 December 2015, is a re-presentation of the curatorial material from the Bodleian’s display, under the direction of the Computer History Museum’s Vice-President of Collections & Exhibitions, Kirsten Tashev.  Supporting activities included an opening event with YouTube CEO Susan Wojcicki, family fun days,  demonstrations of the modern  reconstruction of Babbage’s unbuilt Difference Engine,  a parallel US version of the ‘Write a letter to Ada’ competition, and a panel discussion with  Oxford’s Ursula Martin, Ada Lovelace biographer Dr Betty Toole, and Charles Babbage expert Tim Robinson.

There is more to come, including a movie biopic from Alison Owen and Debra Hayward’s Monumental Pictures, in partnership with google and the National Academy of Sciences.

The Ada Lovelace Hackathon

Back in November, the folks at the Oxford Hackspace kindly hosted our hackathon to celebrate the life and works of Ada Lovelace. The hackathon was co-ordinated by Computer Science PhD student Beth McMillan, who wrote the following report.

Lovelace investigated and talked about many concepts that lend themselves to physical computing projects.

“It does not appear to me that cerebral matter need be more unmanageable to mathematicians than sideral & planetary matters & movements, if they would but inspect it from the right point of view.”

Lovelace’s idea for a so-called “calculus of the nervous system” has been realised in various ways by mathematical biologists, ever since Hodgkin and Huxley modelled a squid axon in 1952. An entertaining recent development was the creation of a robot that responded to stimuli based on the neuronal connections of a nematode worm. Some scientists from OpenWorm group were kind enough to come along to the hackathon to lead a project, and ended up working on a SPARKLY calculus of the nervous system.



“Supposing, for instance, that the fundamental relations of pitched sounds in the science of harmony and of musical composition were susceptible of such expression and adaptations, the engine might compose elaborate and scientific pieces of music of any degree of complexity or extent.”

Lovelace predicted the advent of electronic music long before the birth of Delia Darbyshire. The possibilities for creating music machines and electronic compositions are practically infinite – one could use Markov chains to approximate a Bach chorale, play the ZX Spectrum like an instrument, or, as one group attempted, use a robot arm to play a glockenspiel.


Sadly, the weight of the mallet overcame the little robot arm. A few days later, however, the glorious hackspace nerds collaboratively built this, using an ardiuno and some motors:

As a young girl, Ada’s interest in “Flyology” lead her to investigate the best materials and designs for creating flying machines. Our Flyology department decided on a classic ornithopter design.

We’re lucky enough to be living at a time when 3D printing is cheap and readily available.

This meant we could, amongst other projects, replicate this part of the Analytical Engine’s adding mechanism:

We had around 45 participants, and there were around 10 experts from the hackspace volunteering as well. We had some Oxford students, some local folks, some teenagers, and a group of people all the way from Brunel!

The hackathon was run in an “unconference” manner: knowledgeable people shared their skills, and people formed their own groups to work on self-directed projects. Periodically we assembled for plenaries to talk about what we were making.

Three people also did short talks on their areas of expertise: the excellent Peter Lister introduced us to Arduino electronics, the brilliant Paul Murcutt explained neural networks, and the glorious Sydney Padua taught us about the Analytical Engine.

There was a Twitter feed running throughout the day, showing the internet what we were up to. All in all, it was an excellent day and I think everyone left having learned something. If Ada Lovelace were alive today, I think she would have been pretty excited.

Numbers into Notes – Ada Lovelace and Music

Ada Lovelace’s significant contributions were celebrated and discussed at the Ada Lovelace Symposium last week, marking the bicentennial of her birth on 10 December 1815.  Lovelace brought important early insights into mathematics and computation, especially in the context of the Analytical Engine proposed by her collaborator Charles Babbage. She also brought her vision and computational intuitions to music, asking whether ‘the engine might compose elaborate and scientific pieces of music of any degree of complexity or extent’.

On 30 November we explored mathematics, computation, and music through a performance of ‘Ada sketches‘, a short operatic work by composed by Emily Howard and part of her Lovelace Trilogy. More than a performance, this event with Emily Howard and musicians from the Northern Royal College of Music involved mathematical explanation and engaged the audience in composition, turning numbers into notes. We revisited this work at the Ada Lovelace Symposium through an interactive display and a conversation on stage between David De Roure and Emily Howard, herself a mathematician, computer scientist and musician.  This also featured an extract of Howard’s work ‘Mesmerism’, another part of the Trilogy, and illustrated numbers and notes by generating a number sequence on a simulator of the Analytical Engine and developing the output as a musical theme—an exercise inspired by discussions at a music hack day held at Goldsmiths in October. The evening saw world premières of  ‘An algorithmic study on ADA’ and ‘ADA’, composed by James Whitbourn, performed by mixed-voice contemporary choir with violin and harp.

The event was supported by digital music research projects Transforming Musicology(AHRC, led by Goldsmiths, University of London) and “FAST” (EPSRC, led by Queen Mary University of London), and organized at University of Oxford by a partnership of thee-Research Centre, Centre for Digital Scholarship, and The Oxford Research Centre for the Humanities, in collaboration with symposium organizer Professor Ursula Martin, theMathematical Institute, and Department of Computer Science.  The performance was supported by the Royal Northern College of Music, Leverhulme Trust and University of Liverpool.

Somerville, science and wikipedia

Whilst Time is Unveiling

By William Skelton (engraver); Charles Reuben Ryley (artist) (The Bodleian Libraries, Oxford) [CC BY 4.0], via Wikimedia Commons

From Martin Poulter, Bodleian Libraries Wikimedian in Residence

In the early 19th century, Mary Somerville was a celebrity scientist. One of her works was the best-selling science book of the time, until overtaken by Darwin’s On the Origin of Species. She published on astronomy, biology, atomic theory, and physical geography, at a time when scientific publications by women were rare. She tutored the computing pioneer Ada Lovelace, and introduced Lovelace to Charles Babbage.

Somerville’s name lives on, not least in the Oxford college named in her honour, yet not many people today know of her achievements. One reason is that it is hard to find her works. Her publications have been digitised, but the digitisation process only created images – rather than text, which is easy to find, search within and quote.

On 12 October, a group brought together by University of Oxford IT Services and the Bodleian Libraries started to change that. Working together on Wikisource, a sister-project of Wikipedia, we published a definitive transcription of a Mary Somerville paper from 1826. Being totally open access, the paper incidentally now meets modern funders’ requirements for scientific research outputs.

We also began that day a transcription of Somerville’s Preliminary Dissertation on the Mechanisms of the Heavens; a book described by the astronomer John Herschel as ‘by far the best condensed view of the Newtonian philosophy which has yet appeared’. The transcription was finished this month, and it and other texts are available through Somerville’s Wikisource profile.

This event was just one of a larger programme celebrating the bicentenary of Ada Lovelace. They involved Oxford staff, interested public and experienced Wikipedians, a couple of whom participated remotely. We were lucky to have two excellent guest speakers in Prof Ursula Martin and Prof Sylvia McLain. Each event improved a different aspect of open knowledge about women’s achievements in science and related fields.

In the edit-a-thon and improve-a-thon, we created 8 Wikipedia articles about notable women scientists — some living, some historic — and improved a further 16 existing articles. Creating an article from scratch can be a time-consuming process, but fixing clumsy wording or adding a cited fact is relatively quick.

Wikipedia’s new visual editor works like a word processor, so new users can write or improve articles without having to learn wiki code. We found that this makes Wikipedia editing much quicker to learn, quicker to do, and hence more enjoyable.

Our goal was not just to write biographies but to improve the web of knowledge to fairly represent women’s achievements. Amongst the non-biography articles we improved were those on Mary Somerville’s bestseller On the Connexion of the Physical Sciences and on the Finkbeiner test — important reading for anyone who writes about women scientists!

The 4th workshop was an image-a-thon, looking at Wikipedia’s sister project, Wikimedia Commons, and at some images of women scientists not yet used in Wikipedia. We also uploaded images from copyright-free sources, improving a total of 20 Wikipedia articles.

A call for material for the image-a-thon drew responses from private collections and cultural institutions. Among the contributions from The John Johnson Collection of Printed Ephemera is the accompanying illustration from a museum ticket, which now illustrates the Women in science article.

The records of what we did, including the articles edited, images uploaded and feedback are all openly available. More importantly, the process is ongoing. There are more articles that need expanding, re-wording, illustrating, or creating and anyone can join in: see the project pages for more details.

We will keep in touch with the participants and hope they continue as Wikipedians. The feedback from participants includes, ‘I found the session really useful and fun’ and ‘found it a very rewarding and useful experience and would like to continue contributing’ among similar comments, indicating that for some, we have started a habit.

Only known photographs of Ada Lovelace in Bodleian Display

The Bodleian Libraries is hosting a special display to celebrate the 200th anniversary of the birth of Ada, Countess of Lovelace, the Victorian mathematician who is often referred to as the first computer programmer. It contains two  remarkable daguerreotypes, one reproduced here, a pair made by made by Antoine Claudet in the early 1840s. They  are the only known photographs of Lovelace.

Daguerreotype of Ada Lovelace, about 1843, reproduced by courtesy of G M Bond

Claudet learned the art of photography from Louis Daguerre, the inventor of one of the earliest photographic processes. He established his first Daguerreotype studio in London, in the Strand, in 1841, then moved to Regent’s Park and finally Regent’s Street. His output was phenomenal – over 1800 portraits a year – and his customers included many well known figures in fashionable, literary and scientific circles, among them Michael Faraday, Charles Babbage and Ada Lovelace.

He would often take several pictures of his subjects at the same sitting, using elaborate painted backdrops, which recur in several of his images. These allow us to date these pictures of Lovelace to around 1843, at the time when she was writing her famous paper on Babbage’s Analytical Engine.

As well as being customers of the new photographers, Ada Lovelace and her circle were intrigued by the science of photography and the contribution photographic processes might make to science. Apart from her famous paper on Babbage’s Analytical Engine, her only other known publication is in the form of long footnotes to an article by her husband, William Earl of Lovelace, in the Royal Agricultural Society journal. The article, which he describes as being written for the ‘leather-gaiter-and-top-boot-mind’, reviews a paper by the French economist Gasparin, about possible laws linking climate and the yield of crops, referring to a wide variety of observations of weather and plants collected by both professionals and amateurs. Ada Lovelace observes that photographic devices, such as the actinograph designed by her friend John Herschel, allow the construction of ‘meteorological instruments of the utmost delicacy’, and criticises Gasparin ‘who seems to write unaware of the means which photography has offered’.

In similar vein, she reflected on the potential of photography in providing objective evidence of psychic phenomena. In an unpublished article she writes, ‘If amateurs, of either sex, would amuse their idle hours with experimenting on this subject, & would keep an accurate journal of their daily observations, we should in a few years have a mass of registered facts to compare with the observation of the Scientific’, concluding that ‘we believe that it is as yet quite unsuspected how important a part photography is to play in the advancement of human knowledge’.

A third poignant daguerreotype, by an unknown photographer, is a photograph of a small portrait of Ada Lovelace, frail and thin, painted by Henry Wyndham Phillips in the last months of her life, when she was in great pain from uterine cancer.  Her husband recorded progress on the portrait in his diary – on 2 August ‘she managed to remain long enough when he came for him to make some progress’, on 3 August that he was ‘getting on with the portrait’, and on 13 August that though ‘the suffering was so great that she could scarce avoid crying out’, yet ‘she sat at the piano some little time so that the artist could portray her hands’. The Bodleian archives contain a note written in her last days, in which she leaves ‘a daguerreotype from Philips’s portrait of me’ to her mother’s friend, Miss Montgomery.

Over the coming months, the University of Oxford will celebrate the 200th anniversary of the birth of computer visionary Ada Lovelace.  The centrepiece of the celebrations will be a display at the Bodleian Library (13 October – 23 December 2015) and a Symposium (9 and 10 December 2015); other events including Wikipedia editathons, hackathons and workshops. For more information, please keep an eye on this website, where we’ll be listing events and other news.

Ada Lovelace on the BBC

Those of you with an interest in Ada Lovelace will want to tune into a number of upcoming programmes on BBC Four and Radio 4 – mark your calendars!

The Letters of Ada Lovelace
11am, 14 and 21 September, Radio 4

Georgina Ferry presents the correspondence of Ada Lovelace, dramatized by an all-star cast. Uninterested in Ada the feminist icon or crazy fantasist, she reveals the intense inner world of a young Victorian lady who anticipated our digital age, when steam power was still the new big thing.

Calculating Ada: The Countess of Computing
9pm, 17 September, BBC Four

In this new film, Dr Hannah Fry tells the story of Ada Lovelace. Born in the early 19th-century Ada was a countess of the realm, a scandalous socialite and an ‘enchantress of numbers’. The film is an enthralling tale of how a life infused with brilliance, but blighted by illness and gambling addiction, helped give rise to the modern era of computing.

In this clip from the film, Hannah Fry explains that Ada’s real claim to fame was that she was the first pioneer to realise the true versatility of computers.
