Ann Oakley was born in London in 1944. She was the only child of Kay Titmuss, a social worker, and Richard Titmuss, one of the 20th century's foremost social policy theorists and an architect of Britain's welfare state. She lived with her parents in West London and went to a single-sex grammar school until the age of 16 when she escaped to the less authoritarian setting of what was then called a polytechnic. Here she met men of her own age for the first time, became a political radical, and took A levels in English, French and Art. At 18 she went to Somerville College, Oxford, to study for a degree in Philosophy, Politics and Economics. She was one of the first students to take a Sociology option in this degree at Oxford in 1964. Her biography of her parents' early work, Man and Wife, published in 1996, contains some reflections on the relationship between her early family life and her own subsequent life and work. Father and Daughter, published in 2014, continues this project by looking at the development of her own and her father's work in the context of twentieth century British social science.
After university, Ann Oakley wrote two novels, but had difficulty finding a publisher, She did a variety of part-time jobs, in market research, telephone sales, doing contract research in education, and writing scripts for children's television. Her first two children were born in 1967 and 1968. In 1969 she registered for a PhD on women's attitudes to housework, a subject that much puzzled the academic establishment at the time. Her first academic book, Sex, Gender and Society was published in 1972. This introduced the term 'gender' into academic and everyday discourse, and provided a very useful tool for the developing field of women's studies: 'gender' distinguishes the social treatment of men and women from the biology of sex. By this time, Ann Oakley had discovered feminism, and had joined the infant women's liberation movement. Two books on the housework project followed in 1974, The Sociology of Housework and Housewife. These pointed out that the social sciences ignored housework as work, and that very few serious studies of women's work in the home existed.
Ann Oakley became a researcher at what was then Bedford College, London University, for her next project: women's experiences of the transition to motherhood. This again resulted in two books, Becoming a Mother (1979), later reprinted as From Here to Maternity, and Women Confined: Towards a sociology of childbirth (1980). These looked at childbirth as a human life event, and on medicine as a controlling institution. In 1977 she had a third child, and soon afterwards was treated for oral cancer. In 1979 she moved to a part-time job at a research unit in Oxford (the National Perinatal Epidemiology Unit in Oxford set up by the pioneering health services researcher Sir Iain Chalmers), where she carried out a project looking at the history of antenatal care. This became a book: The Captured Womb (1984). In the same year she published an account of her life so far, Taking it Like a Woman. Like much of her work, this departed from normal writing conventions, here in mixing autobiography with fictionalised narratives about a love affair. A book of essays combined with poetry, Telling the Truth About Jerusalem (1986), came next, though the poetry was left out of the second edition which appeared as Essays on Women, Medicine and Health (1993).
Ann Oakley's first published novel, The Men's Room, appeared in 1988. This was made into a successful BBC television film series starring Harriet Walter and Bill Nighy. Six other novels, exploring many of the themes that have preoccupied her as a social science researcher, were published between 1990 and 1999. Her last two novels are sitting in a filing cabinet, waiting for a publisher.
