In a footnote to my recent post on the mythologizing of Ibn al-Haytham I briefly noted the inadequacy of the terms Arabic science and Islamic science, pointing out that there were scholars included in these categories who were not Muslims and ones who were not Arabic. In the comments Renaissance Mathematicus friend, the blogger theofloinn, asked, Who were the non-muslim “muslim” scientists? And (aside from Persians) who were the non-Arab “arab” scientists? And then in a follow up comment wrote, I knew about Hunayn ibn Ishaq and the House of Wisdom, but I was not thinking of translation as “doing science.” From the standpoint of the historian of science this second comment is very interesting and reflects a common problem in the historiography of science. On the whole most people regard science as being that which scientists do and when describing its history they tend to concentrate on the big name scientists.
This attitude is a highly mistaken one that creates a falsified picture of scientific endeavour. Science is a collective enterprise in which the ‘scientists’ are only one part of a collective consisting of scientists, technicians, instrument designers and makers, and other supportive workers without whom the scientist could not carry out his or her work. This often includes such ignored people as the secretaries, or in earlier times amanuenses, who wrote up the scientific reports or life partners who, invisible in the background, often carried out much of the drudgery of scientific investigation. My favourite example being William Herschel’s sister and housekeeper, Caroline (a successful astronomer in her own right), who sieved the horse manure on which he bedded his self cast telescope mirrors to polish them.
Translators very definitely belong to the long list of so-called helpers without whom the scientific endeavour would grind to a halt. It was translators who made the Babylonian astronomy and astrology accessible to their Greek heirs thus making possible the work of Eudoxus, Hipparchus, Ptolemaeus and many others. It was translators who set the ball rolling for those Islamic, or if you prefer Arabic, scholars when they translated the treasures of Greek science into Arabic. It was again translators who kicked off the various scientific Renaissances in the twelfth and thirteenth-centuries and again in the fifteenth-century, thereby making the so-called European scientific revolution possible. All of these translators were also more or less scientists in their own right as without a working knowledge of the subject matter that they were translating they would not have been able to render the texts from one language into another. In fact there are many instances in the history of the transmission of scientific knowledge where an inadequate knowledge of the subject at hand led to an inaccurate or even false translation causing major problems for the scholars who tried to understand the texts in the new language. Translators have always been and continue to be an important part of the scientific endeavour.
The two most important works on celestial mechanics produced in Europe in the long eighteenth-century were Isaac Newton’s Philosophiæ Naturalis Principia Mathematica and Pierre-Simon, marquis de Laplace’s Mécanique céleste. The former was originally published in Latin, with an English translation being published shortly after the author’s death, and the latter in French. This meant that these works were only accessible to those who mastered the respective language. It is a fascinating quirk of history that the former was rendered into French and that latter into English in each case by a women; Gabrielle-Émilie Le Tonnelier de Breteuil, Marquise du Châtelet translated Newton’s masterpiece into French and Mary Somerville translated Laplace’s pièce de résistance into English. I have blogged about Émilie de Châtelet before but who was Mary Somerville? (1)
Mary Somerville by Thomas Phillips
She was born Mary Fairfax, the daughter of William Fairfax, a naval officer, and Mary Charters at Jedburgh in the Scottish boarders on 26 December 1780. Her parents very definitely didn’t believe in education for women and she spent her childhood wandering through the Scottish countryside developing a lifelong love of nature. At the age of ten, still semi-illiterate, she was sent to Miss Primrose’s boarding school at Musselburgh in Midlothian for one year; the only formal schooling she would ever receive. As a young lady she received lessons in dancing, music, painting and cookery. At the age of fifteen she came across a mathematical puzzle in a ladies magazine (mathematical recreation columns were quite common in ladies magazines in the 18th and 19th-centuries!) whilst visiting friends. Fascinated by the symbols that she didn’t understand, she was informed that it was algebra, a word that meant nothing to her. Later her painting teacher revealed that she could learn geometry from Euclid’s Elements whilst discussing the topic of perspective. With the assistance of her brother’s tutor, young ladies could not buy maths-books, she acquired a copy of the Euclid as well as one of Bonnycastle’s Algebra and began to teach herself mathematics in the secrecy of her bedroom. When her parents discovered this they were mortified her father saying to her mother, “Peg, we must put a stop to this, or we shall have Mary in a strait jacket one of these days. There is X., who went raving mad about the longitude.” They forbid her studies, but she persisted rising before at dawn to study until breakfast time. Her mother eventually allowed her to take some lessons on the terrestrial and celestial globes with the village schoolmaster.
In 1804 she was married off to a distant cousin, Samuel Grieg, like her father a naval officer but in the Russian Navy. He, like her parents, disapproved of her mathematical studies and she seemed condemned to the life of wife and mother. She bore two sons in her first marriage, David who died in infancy and Woronzow, who would later write a biography of Ada Lovelace. One could say fortunately, for the young Mary, her husband died after only three years of marriage in 1807 leaving her well enough off that she could now devote herself to her studies, which she duly did. Under the tutorship of John Wallace, later professor of mathematics in Edinburgh, she started on a course of mathematical study, of mostly French books but covering a wide range of mathematical topic, even tacking Newton’s Principia, which she found very difficult. She was by now already twenty-eight years old. During the next years she became a fixture in the highest intellectual circles of Edinburgh.
In 1812 she married for a second time, another cousin, William Somerville and thus acquired the name under which she would become famous throughout Europe. Unlike her parents and Samuel Grieg, William vigorously encouraged and supported her scientific interests. In 1816 the family moved to London. Due to her Scottish connections Mary soon became a member of the London intellectual scene and was on friendly terms with such luminaries as Thomas Young, Charles Babbage, John Herschel and many, many others; all of whom treated Mary as an equal in their wide ranging scientific discussions. In 1817 the Somervilles went to Paris where Mary became acquainted with the cream of the French scientists, including Biot, Arago, Cuvier, Guy-Lussac, Laplace, Poisson and many more.
In 1824 William was appointed Physician to Chelsea Hospital where Mary began a series of scientific experiments on light and magnetism, which resulted in a first scientific paper published in the Philosophical Transactions of the Royal Society in 1826. In 1836, a second piece of Mary’s original research was presented to the Académie des Sciences by Arago. The third and last of her own researches appeared in the Philosophical Transactions in 1845. However it was not as a researcher that Mary Somerville made her mark but as a translator and populariser.
In 1827 Henry Lord Brougham and Vaux requested Mary to translate Laplace’s Mécanique céleste into English for the Society for the Diffusion of Useful Knowledge. Initially hesitant she finally agreed but only on the condition that the project remained secret and it would only be published if judged fit for purpose, otherwise the manuscript should be burnt. She had met Laplace in 1817 and had maintained a scientific correspondence with him until his death in 1827. The translation took four years and was published as The Mechanism of the Heavens, with a dedication to Lord Brougham, in 1831. The manuscript had been refereed by John Herschel, Britain’s leading astronomer and a brilliant mathematician, who was thoroughly cognisant with the original, he found the translation much, much more than fit for the purpose. Laplace’s original text was written in a style that made it inaccessible for all but the best mathematicians, Mary Somerville did not just translate the text but made it accessible for all with a modicum of mathematics, simplifying and elucidating as she went. This wasn’t just a translation but a masterpiece. The text proved too vast for Brougham’s Library of Useful Knowledge but on the recommendation of Herschel, the publisher John Murray published the book at his own cost and risk promising the author two thirds of the profits. The book was a smash hit the first edition of 750 selling out almost instantly following glowing reviews by Herschel and others. In honour of the success the Royal Society commissioned a bust of Mrs Somerville to be placed in their Great Hall, she couldn’t of course become a member!
At the age of fifty-one Mary Somerville’s career as a science writer had started with a bang. Her Laplace translation was used as a textbook in English schools and universities for many years and went through many editions. Her elucidatory preface was extracted and published separately and also became a best seller. If she had never written another word she would still be hailed as a great translator and science writer but she didn’t stop here. Over the next forty years Mary Somerville wrote three major works of semi-popular science On the Connection of the Physical Sciences (1st ed. 1834), Physical Geography (1st ed. 1848), (she was now sixty-eight years old!) and at the age of seventy-nine, On Molecular and Microscopic Science (1st ed. 1859). The first two were major successes, which went through many editions each one extended, brought up to date, and improved. The third, which she later regretted having published, wasn’t as successful as her other books. Famously, in the history of science, William Whewell in his anonymous 1834 review of On the Connection of the Physical Sciences first used the term scientist, which he had coined a year earlier, in print but not, as is oft erroneously claimed, in reference to Mary Somerville.
Following the publication of On the Connection of the Physical Sciences Mary Somerville was awarded a state pension of £200 per annum, which was later raised to £300. Together with Caroline Herschel, Mary Somerville became the first female honorary member of the Royal Astronomical Society just one of many memberships and honorary memberships of learned societies throughout Europe and America. Somerville College Oxford, founded seven years after her death, was also named in her honour. She died on 28 November 1872, at the age of ninety-one, the obituary which appeared in the Morning Post on 2 December said, “Whatever difficulty we might experience in the middle of the nineteenth century in choosing a king of science, there could be no question whatever as to the queen of science.” The Times of the same date, “spoke of the high regard in which her services to science were held both by men of science and by the nation”.
As this is my contribution to Ada Lovelace day celebrating the role of women in the history of science, medicine, engineering, mathematics and technology I will close by mentioning the role that Mary Somerville played in the life of Ada. A friend of Ada’s mother, the older women became a scientific mentor and occasional mathematics tutor to the young Miss Byron. As her various attempts to make something of herself in science or mathematics all came to nought Ada decided to take a leaf out of her mentor’s book and to turn to scientific translating. At the suggestion of Charles Wheatstone she chose to translate Luigi Menabrea’s essay on Babbage’s Analytical Engine, at Babbage’s suggestion elucidating the original text as her mentor had elucidated Laplace and the rest is, as they say, history. I personally would wish that the founders of Ada Lovelace Day had chosen Mary Somerville instead, as their galleon figure, as she contributed much, much more to the history of science than her feted protégée.
