Dr Catherine Hamlin, née Nicholson, was born in Sydney Australia and graduated from the University of Sydney in 1946. She met and married Dr Reginald Hamlin, a New Zealander, when they were both Senior Medical Administrators at Crown Street Women's Hospital, Sydney.
In 1958 they answered an advertisement in the Lancet Medical Journal for an obstetrician and gynaecologist to establish a Midwifery School at the Princess Tsehay Hospital in Addis Ababa. They arrived in Addis Ababa in 1959 on a three year contract with the Ethiopian Government.
They began working in the hospital and training midwives. However, after a short while the Ethiopian Government advised the Hamlins that it would not be able to afford to pay the higher salaries of the trained midwives. Only about 10 midwives had been trained before the the Government closed the midwifery school.
By then, however, the Hamlins had seen women arriving at the hospital who were incontinent and smelling. They were outcast even by the other patients. No one at the hospital knew how to treat these women.
The Hamlins had never seen an obstetric fistula before. "To us they were an academic rarity," Catherine recalls in her book, The Hospital by the River.
One fellow gynaecologist told them that the "fistula patients will break your hearts". And this is exactly what they did. In response the Hamlins set about finding a cure.
