@ On one level Margaret Sanger's achievement was a purely practical one: to open birth control clinics in the face of fierce opposition from the bureaucracy and from self- appointed moral policemen. But her real legacy is the idea that a woman's body is hers to control, that she has the right to take control of her own fertility # Working as a nurse in New York's Lower East Side, Margaret Sanger became distressed at the link she saw between unwanted pregnancies, back- street abortions, poverty, and child mortality. But under US law it was "obscene" to let women have written information about birth control # At the time, Europe had a slightly more liberal attitude to birth control. Hoping to learn from European experience, Sanger left the US, meeting campaigners such as British birth control pioneer Marie Stopes # Returning to New York, Sanger opened a birth control and health clinic in Brooklyn. But the authorities closed it down and she was sentenced to thirty days in the workhouse for "causing a public nuisance". She was arrested eight times in her struggle for contraception and sex education # Margaret Sanger was concerned for the rights of women the world over. In 1927 she organised the first World Population Conference in Geneva and for the next three decades lectured as far afield as China and the Far East @
