Born into a well-to-do family in Edinburgh, Sarah was the daughter of daughter of Major Arthur Mair of the 62nd Regiment and Elizabeth Harriot Mair. She was the granddaughter of actor Henry Siddons and great-granddaughter of actress Sarah Siddons. Mair started the Edinburgh Essay Society, soon renamed the Ladies' Edinburgh Debating Society when she was 19. Mair was president of the society for 70 years. The society met in the spacious Mair family home in the New Town and offered Edinburgh women of a certain background the chance to discuss social questions while learning public speaking and debating skills. They published the Ladies' Edinburgh Magazine, called The Attempt until 1876, which linked them with readers across the country. It was edited by Mair and Helen Reid. Charlotte Yonge contributed, and Mair reviewed Josephine Butler's essay collection Women's Work and Women's Culture. This society and its headquarters in the Mair dining-room were the focus of much effort to promote women's rights and education, spearheaded by women from professional, usually prosperous families. Louisa and Flora Stevenson were early members, as were Louisa Lumsden, founder of St Leonards School in St Andrews, and Charlotte Carmichael, mother of Marie Stopes. The society debated the question of women's suffrage at intervals, with Mair a lifelong supporter of votes for women. In 1866 and 1872, Sarah Mair found that she and her fellow-suffragists were in the minority, but from 1884 onwards motions in favour of women's suffrage were carried by increasing majorities. Mair belonged to the Edinburgh National Society for Women's Suffrage which had been established in 1867 as the first Scottish society campaigning for votes for women and which sent speakers, including Dr. Elsie Inglis, who was honorary secretary from 1906, and others to events all over Scotland. Later Mair became president of the society, and then president of the Scottish Federation of Women's Suffrage Societies. She was often able to mediate between groups with different approaches to campaigning for the vote. Once women over 30 were enfranchised in 1918 she led the Suffrage Society into a new phase as the Society for Equal Citizenship. Sarah Mair was an important member of the Edinburgh Ladies' Educational Association in 1867. She was present at the meeting when the Association was founded, but was not considered a founder member, presumably because she was unmarried and rather young. She and Mary Crudelius were willing to proceed one step at a time towards their goal of equal access to university education for both sexes, with Mair believing a practical approach would lead to the right results. However, ultimately they wanted more than a separate system for women, however good the teaching. In 1876, there was an effort to improve the pre-university stage of women's education and advertised classes in St. George's Hall to help women pass university entrance level qualification. They developed correspondence courses for women who could not attend classes, and then in 1886 she was involved with others like Mary Russell Walker in setting up St George's Training College, followed by St. George's High School for Girls in 1888. The training college was the first Scottish institution training women to teach insecondary schools and the high school was the first Scottish day school for girls which taught them all the way up to university entrance level. Girls from St. George's were among the first female graduates of Edinburgh University. Mary Russell Walker returned from London in 1885, qualified to lead the college and later the school. During the First World War Mair's association with Elsie Inglis, begun as fellow suffragists, continued as she was president of the Hospitals Committee of the Scottish Women's Hospitals for Foreign Service, whose funding was raised from contacts in Edinburgh and beyond. Mair also acted as treasurer of the Edinburgh Association for the University Education of Women's Masson Hall project, and chaired committees of the Bruntsfield Hospital for Women and Children and the Elsie Inglis Memorial Maternity Hospital. She also found time to prove a woman could have skill in both archery and chess, and belonged to the Ladies' Chess Club.
