Mary Jermyn Heseltine (1910–2002) was an Australian pathologist "and an early and forceful proponent of the adoption and use in Australia of the Pap smear for detecting cervical cancer."[1]
Heseltine attended Ballarat Grammar School from 1921 until 1927[2] before she graduated from PLC Melbourne and the University of Melbourne (MBBS 1934).[3] She went to the Cornell University Medical School in 1955 to study cytology with George Papanicolaou who invented the Pap smear. When she returned to Australia, she began the first gynaecological cytology unit in Australia at the King George V Memorial Hospital.
