Jack Lang was born to a poor watchmaker’s family in Sydney in 1876. He was twice premier of NSW and founder of two breakaway Labor parties. Lang lives on in the popular imagination as that hapless figure at the opening of the Sydney Harbour Bridge in 1932, upstaged when the sword-wielding Captain de Groot of the right-wing New Guard rode in and slashed Lang’s official opening ribbon. De Groot’s ribbon-slashing wins passing notice in Frank Cain’s story of Jack Lang. Very little else in Lang’s life does. His youthful encounters with socialism during the 1890s Depression, his marriage to Hilda Bredt – daughter of feminist–socialist Bertha Bredt – or his success as a real estate agent in Auburn are not important in this story, for Cain places Lang firmly within a framework of economic and constitutional history.
