but the low salaries were less of the barrier to the single woman than to the married man. By the late 1860s a number of schools were preparing women for careers as governesses or teachers. The census reported in 1851 that 70,000 women in England and Wales were teachers, compared to the 170,000 who comprised three-fourths of all teachers in 1901. The great majority came from lower middle class origins. The National Union of Women Teachers (NUWT) originated in the early 20th century inside the male-controlled National Union of Teachers (NUT). It demanded equal pay with male teachers, and eventually broke away. Oxford and Cambridge minimized the role of women, allowing small all-female colleges to operate. However the new redbrick universities and the other major cities were open to women. Medicine was the greatest challenge, with the most systematic resistance by the physicians, and the fewest women breaking through. One route to entry was to go to the United States where there were suitable schools for women as early as 1850. Britain was one of the last countries to train women physicians, so 80 to 90% of the British women came to America for their medical degrees. Edinburgh University admitted a few women in 1869, then reversed itself in 1873, leaving a strong negative reaction among British medical educators. The first separate school for women physicians opened in London in 1874 to a handful of students. Scotland was more open. Coeducation had to wait until the World War. By the end of the nineteenth century, women had secured equality of status in most spheres – except of course for the vote and the holding of office. Child custody Before 1839 after the divorce rich women lost control of their children as those children would continue in the family unit with the father, as head of the household, and who continued to be responsible for them. Caroline Norton was one such woman; her personal tragedy where she was denied access to her three sons after a divorce led her to a life of intense campaigning which successfully led to the passing of the Custody of Infants Act 1839 and introduced the Tender years doctrine for child custody arrangement. The Act gave women, for the first time, a right to their children and gave some discretion to the judge in child custody cases. Under the doctrine, the Act also established a presumption
