More About Mary Somerville
Mary Fairfax, born in Jedburgh, Scotland, as the fifth of seven children of Vice-Admiral Sir William George Fairfax and Margaret Charters Fairfax, preferred the outdoors to reading. She did not have a good experience when sent to an elite boarding school, and was sent home in just a year.
At age 15 Mary noticed some algebraic formulas used as decoration in a fashion magazine, and on her own began to study algebra to make sense of them. She surreptitiously obtained a copy of Euclid's Elements of Geometry over her parents' opposition.
In 1804 Mary Fairfax married -- under pressure from family -- her cousin, Captain Samuel Greig. They had two sons. He too opposed Mary's studying mathematics and science, but after his death in 1807 -- followed by the death of one of their sons -- she returned to Scotland with her other son and began to study astronomy and mathematics seriously. She began solving math problems posed by a mathematics journal, and in 1811 won a medal for a solution she submitted.
She married Dr. William Somerville in 1812, another cousin. A surgeon, Dr. Somerville supported her study, writing and contact with scientists. They had three daughters and a son.
Four years after this marriage Mary Somerville and her family moved to London. They also traveled extensively in Europe. Mary Somerville began publishing papers on scientific subjects in 1826, using her own research, and after 1831, she began writing about the ideas and work of other scientists, too. One book prompted John Couch Adams to search for the planet Neptune, for which is he is credited as a co-discoverer.
Mary Somerville's translation and expansion of Pierre Laplace's Celestial Mechanics in 1831 won her acclaim and success. In 1833 Mary Somerville and Caroline Herschel were named honorary members of the Royal Astronomical Society, the first time women had won that recognition. Mary Somerville moved to Italy for her husband's health in 1838, and there she continued to work and to publish. Dr. Somerville died in 1860. In 1869, Mary Somerville published yet another major work, was awarded a gold medal from the Royal Geographical Society, and was elected to the American Philosophical Society.
Mary Somerville died in Naples in 1872, just before turning 92. She had been working on another mathematical article at the time. Her daughter published Personal Recollections of Mary Somerville the next year.
