Harold Cazneaux was the greatest Australian photographer of the early 20th century. In 1933, he took this image entitled ‘The Anaesthetist’. It is an important documentation of a clinical anaesthetist of the era and was exhibited internationally. Such photographs of specific medical scenarios are rare and valuable. The anaesthetist is Dr Frederick J. Bridges who worked at Royal Prince Alfred and Royal North Shore Hospitals in Sydney. He is using a Clements ether vaporizer which was Australian made. The patient is Cazneaux's daughter. Cazneaux has captured perfectly the care and concern of the anaesthetist for his patient.
