Marjorie Dalgarno

Marjorie Clare Dalgarno (1901–1983) was an Australian radiologist and a pioneer of mammography. She performed the first mammogram in Australia at the Rachel Forster Hospital and demonstrated the benefits of mammography as a breast cancer screening tool.

Biography Dalgarno was born in Sydney in 1901 and studied medicine at the University of Sydney's Women's College. She graduated in 1925 and was hired as a resident medical officer at the Royal Prince Alfred Hospital, where she worked in the radiology department. After marrying Harold McCredie, a general practitioner, in 1928, she established a radiological practice based out of their home in Campsie. Her home practice included an x-ray machine installed in the dining room and a laundry that was converted into a darkroom for developing x-ray films. In 1939, she began working at the Rachel Forster Hospital in Redfern and the Renwick Hospital for Infants in Summer Hill; she also worked at the Western Suburbs Hospital in Croydon during World War II.
