As a prominent sexologist and a campaigner for birth control, Haire took a leading role in the world's first international conference on birth control in 1922 and organised, with Dora Russell, the World League for Sexual Reform's highly successful 1929 Congress in London. He lectured in America, Germany, France and Spain, and wrote and edited many accessible books on sex education.
In 1940 Haire returned to Australia where he attracted a loyal following, but was also hounded by the security service. The ABC Board was censured in parliament for choosing him as the key speaker in a population debate, and his weekly advice column in the magazine Woman was strongly opposed by the Catholic Church. Peter Coleman called Haire 'one of Australia's most famous freethinkers and sex reformers'. This biography pays a tribute to this tenacious, humane, witty, innovative and brave man's contribution to birth control, sexology and human rights history.
