Norman Haire was a physician who advocated for eugenics, which is the betterment of human population by promoting positive traits, and birth control rights in the twentieth century in both Australia and the UK. In the UK, Haire joined the Malthusian League, a contraception advocacy organization, and helped the League open the first physician-supervised birth control clinic, called Walworth Women’s Welfare Centre in London, England. Throughout his life, Haire worked closely with other well-known contraception and women’s rights advocates in the early 1900s including Margaret Sanger, Marie Stopes, and Havelock Ellis. Haire was also known for his work on sexual rejuvenation, an early twentieth century theory that the male sexual appetite could be restored through vasectomies and hormonal injections. Haire advocated for birth control rights through his practice, conference lectures, radio debates, and published work. His activism in the fields of eugenics, contraception, and sexual reform promoted the emergence of more liberal attitudes towards sex and controlled reproduction and in the twentieth century.
