Jack Critchley

John Owen Critchley, was an Australian politician who served as a Labor member of the South Australian House of Assembly from 1930 to 1933 and then the Australian Senate from 1947 to 1959. Born at Callington in the Adelaide Hills of South Australia, and schooled at Sunnybrae and Petersburg, Critchley completed an apprenticeship as a wheelwright. He was then dismissed for forming a branch of his union. He was a founding member and also served twelve years on the executive committee of the Amalgamated Coach Rolling Stock Makers' and Wheelwrights' Society—later the Australian Coachmakers Employees' Federation then the Vehicle Builders Employees' Federation. He briefly served with the South Australia-raised 10th Battalion on the Western Front in France and Belgium during World War I, but was repatriated as medically unfit, suffering from a neck condition.
