Walter Diesendorf (1906–1975), was an Austrian-born Australian electrical engineer known for his work on high-voltage transmission systems, in particular for the Snowy River Hydro-electric Scheme.
Walter and Margaret Diesendorf, who were both multi-lingual, quickly established themselves in the local engineering and literary communities.
[citation needed] In 1939 Diesendorf gained employment as an assistant-engineer for the power-distribution body, Sydney County Council, to make "abstruse technical calculations for high voltage transmission systems which could not be done by an ordinary engineer in Australia or anywhere else".
After the war he designed transmission systems for a major expansion of the New South Wales power industry.
On his retirement from the Snowy River Authority in 1967, he became Senior Lecturer in electrical engineering at the University of Sydney.
