Gynaecologists Catherine and Reg Hamlin left Australia in 1959 on a short contract to establish a midwifery school in Ethiopia. Almost 50 years later, Catherine is still there, running one of the most outstanding medical programs in the world. The Hamlins dedicated their lives to women suffering the catastrophic effects of obstructed labour. The awful injuries that such labour produces are called fistulae, and until the Hamlins began their work in Ethiopia, fistula sufferers were neglected and forgotten - a vast group of women facing a lifetime of incapacity and degradation. The Hamlins have successfully operated on almost 30,000 women, and the Addis Ababa Fistula Hospital, which they opened in 1975, has become a major teaching institution for surgeons. Since Reg's death, Catherine has continued their work. As well as being made a companion of the Order of Australia, being awarded the ANZAC Peace Prize and the coveted Gold Medal from the Royal College of Surgeons, Catherine was nominated for the Nobel Peace Prize in 1999. The Hospital by the River is Catherine's story.
