Mary Somerville became one of the nineteenth century’s most respected intellectual figures despite growing up at a time when advanced education was rarely available to women. Born Mary Fairfax in Jedburgh, Scotland, in 1780, she developed expertise in mathematics, astronomy and the physical sciences largely through determined self-education.
Her ability to explain difficult scientific ideas to a wider audience made her an important Victorian science writer, while her mathematical knowledge earned the respect of leading thinkers throughout Europe. Somerville also became a friend and mentor to Ada Lovelace, encouraging another remarkable woman to pursue her fascination with mathematics.
Somerville’s life demonstrates how intellectual curiosity could overcome many, although certainly not all, of the restrictions imposed upon women in nineteenth-century society.
Mary Somerville and an Unconventional Education
Somerville’s early education gave little indication of her future scientific achievements. Her formal schooling was limited, and she later recalled that much of her childhood was spent exploring the natural environment rather than studying academic subjects.
Her interest in mathematics developed after encountering algebraic symbols in a magazine. Intrigued by this mysterious mathematical language, she began teaching herself algebra and geometry.
This was not an obvious pursuit for a young woman in Georgian Britain. Mathematics was widely regarded as inappropriate or unnecessary for female education, and members of her family worried that excessive study might damage her health.
Somerville persisted.
1. Teaching Herself Advanced Mathematics
After mastering elementary mathematics, she progressed to increasingly sophisticated works. She studied Euclid and eventually tackled the mathematical writings of Isaac Newton and Pierre-Simon Laplace.
Her progress was remarkable because she lacked the structured university education available to male mathematicians.
Following her second marriage, to army doctor William Somerville in 1812, she found herself in a much more supportive intellectual environment. Her husband encouraged her studies, and she became acquainted with prominent scientists and mathematicians.
Among them were Michael Faraday and Charles Babbage, placing Somerville near the centre of Britain’s expanding scientific community.
From Mathematics to Celebrated Science Writer
Somerville’s reputation grew through her ability not merely to understand advanced science but to communicate it.
In 1826, she published a paper on the magnetic properties of violet rays from the solar spectrum. Soon afterwards, publisher John Murray asked her to produce an accessible account of Laplace’s Mécanique Céleste.
The resulting book, The Mechanism of the Heavens, appeared in 1831.
It was far more than a straightforward translation. Somerville explained the mathematical and astronomical principles underlying Laplace’s work, making difficult continental mathematics more accessible to British readers.
2. Connecting Different Branches of Science
Her next major work, On the Connexion of the Physical Sciences, appeared in 1834 and became enormously successful.
Rather than treating astronomy, physics, chemistry and other disciplines as isolated subjects, Somerville explored the relationships between them. Her approach reflected a growing recognition that natural phenomena could be understood through interconnected physical principles.
She became a populariser of mathematics and astronomy, but the description can understate her achievement. She was not merely simplifying other people’s discoveries; she was synthesising knowledge and identifying relationships across scientific disciplines.
Her work belongs within the wider transformation of 19th century science, when increasingly specialised fields were emerging from the older tradition of natural philosophy.
3. The Woman Who Helped Give Science Its Name
Somerville’s interdisciplinary approach indirectly contributed to the modern vocabulary of science.
In reviewing On the Connexion of the Physical Sciences, philosopher William Whewell discussed the difficulty of describing people who investigated the natural world. The older term “natural philosopher” was becoming inadequate as scientific disciplines multiplied.
Whewell proposed scientist as a possible general term.
Somerville therefore played an intriguing role in the history of scientific identity: a book written by a woman helped prompt discussion that popularised the word eventually used for practitioners of science itself.
Mary Somerville’s careful observation and mathematical reasoning reflected the principles of the scientific method throughout her scientific work.
Why Mary Somerville Became an Enduring Influence
Somerville’s importance extended beyond her books.
She was elected an honorary member of the Royal Astronomical Society in 1835 alongside Caroline Herschel. Women could not then become ordinary fellows, but the honour nevertheless demonstrated the extraordinary standing both had achieved.
Somerville was also an influential female mathematician in an era when women remained largely excluded from universities and scientific institutions.
Her experiences form an important part of the broader history of women in science and technology.
4. Mentor and Friend to Ada Lovelace
One of Somerville’s most significant personal relationships was with the young Ada Lovelace.
Somerville encouraged Lovelace’s mathematical interests and introduced her to members of Britain’s scientific and intellectual circles. Most importantly, she introduced Lovelace to Charles Babbage.
That meeting would prove consequential.
Lovelace became fascinated by Babbage’s calculating machines and later produced her celebrated notes on the Analytical Engine.
Somerville should not be credited with Lovelace’s achievements, but her encouragement and connections helped create an environment in which Lovelace’s mathematical abilities could develop.
This mentoring role strengthens Somerville’s position as a pioneering woman of science whose influence extended beyond her own publications.
Frequently Asked Questions
Conclusion: Mary Somerville and a Life Devoted to Knowledge
Mary Somerville succeeded in a scientific world that offered women few formal opportunities. Through self-education, persistence and extraordinary intellectual curiosity, she became an internationally respected mathematical and scientific author.
Her achievement was not simply acquiring knowledge. She connected ideas across disciplines and communicated difficult concepts with unusual clarity.
Somerville died in Naples in 1872 at the age of 91, still intellectually active late in life. Her name survives in Somerville College, Oxford, as well as in scientific and geographical commemorations.
More importantly, her story demonstrates that the history of science was shaped not only by celebrated experiments and discoveries but also by people capable of connecting knowledge and passing it to others. In doing so, Somerville helped widen both the meaning of science and the possibilities available to the women who followed her.
