Walter Winterton came to Hong Kong in 1938 after the Anschluss made it near impossible for a Jew to practice medicine in his native Vienna.
He befriended Dr. Selwyn-Clarke, the Director of Medical Services, who arranged for him to practice in Guangdong Province.
He had returned to Hong Kong by the time of the Japanese attack in December 1941 and was allowed to continue working during the occupation. His clinic was in Nathan Road, and he offered free treatment to those who could not afford to pay, a mark of his life-long humanitarian commitment.
In 1948 he moved to Australia, where he had a distinguished career in Western Australia serving rural and suburban communities.
