John Ronald Timothy (Jack) Byrne (1894-1962) served in World War I, and was then employed by the council for 25 years. Starting out as a fitter and turner, his activities as a union organiser provoked his employer. He turned the tables in 1950 when he won pre-selection (and election) for Phillip Ward.
He continued as an Alderman in varying wards until he died in 1962. He was Deputy Lord Mayor in 1950, 1952 and 1959 and sat on most of the critical committees.
Michael Matthews rates his most important contribution to Pyrmont and Ultimo as his successful battle to retain some housing stock when planners wanted to transform the peninsula into a completely industrial precinct.
