John Gorman (physician)

John Grant Gorman, (born c. 1931) is an Australian physician and medical researcher. In 1980, Gorman shared the Lasker-DeBakey Clinical Medical Research Award for pioneering work on the rhesus blood group system, the role of rhesus D antibodies in the causation of Rh disease and the apparently paradoxical prevention of Rh disease using the Rh antibodies themselves, in the form of Rho(D) immune globulin, as treatment.

Since its discovery, Gorman's treatment is estimated to have saved millions of lives.

Gorman was appointed an Honorary Companion of the Order of Australia (AC) on 19 July 2024 For "eminent service to medicine in co-discovering and pioneering a treatment for Rhesus disease for worldwide benefit to humanity."
