Janet McCredie AM (1935–2023) was an Australian radiologist who originated the theory of Neural Crest Injury as being the pathogenesis of congenital malformations of the thalidomide type.
[1][2] McCredie was born in Campsie, New South Wales on 14 March 1935[1] to Marjorie Dalgarno, a pioneering radiologist, while her father was obstetrician.
She chose to specialise in radiology, the same field as her mother, and worked as a radiologist at the Royal Prince Alfred Hospital, Sydney from 1965 to 1972.
[2] During the 1980s, she played a crucial role in introducing mammography as a method for early detection of breast cancer, an idea initially advocated by her mother.
[2] In 1994, she was appointed a Member of the Order of Australia for "service to medicine, particularly radiology, and the study of congenital abnormalities of the limbs of newborn babies".
