Doris Blackburn, Australian activist and politician (d. 1970)

Doris Amelia Blackburn (née Hordern; 18 September 1889 – 12 December 1970) was an Australian social reformer and politician. She served in the House of Representatives from 1946 to 1949, the second woman after Enid Lyons to do so. Blackburn was a prominent socialist and originally a member of the Labor Party. She was married to Maurice Blackburn, a Labor MP, but he was expelled from the party in 1937 and she resigned from the party in solidarity. Her husband died in 1944, and she was elected to his former seat at the 1946 federal election – the first woman elected to parliament as an independent. However, Blackburn served only a single term before being defeated. She later served as president of the Women's International League for Peace and Freedom.
