Glen William ("George") Warnecke (30 July 1894 – 2 June 1981) was an Australian journalist, editor, and publisher.

He was born in Armidale, New South Wales and began his journalism career in 1913 as a junior reporter for The Evening News.

In his later years Warnecke settled in Dublin with his Irish-born wife Nora Hill who had had an active career as a concert and opera singer.

The Warnecke family moved to Sydney in 1912 and the following year he joined the Australian Journalists' Association, working as a junior reporter for The Evening News and its offshoot publication, Woman's Budget.

"[1][2][3] His diary entry on his 20th birthday in July 1916 read: Red and green flares burst like a fountain of joyful fireworks from the German lines.

[2]After his discharge from the army, Warnecke resumed his work at The Evening News and became active in the Australian Workers' Union.

However, he found intellectual rewards in London's Bloomsbury quarter where he mixed with Australian writers such as Anna Wickham and Christina Stead and the British communists William Gallacher and Shapurji Saklatvala.

[5] Warnecke's relations with Frank Packer became increasingly strained after 1935 and in April 1939 he resigned from Consolidated Press.

In 1940 he became a foreign correspondent for the McClure Newspaper Syndicate and in 1943 joined the US Office of War Information as a special writer.

He served as a consultant to Murdoch and tried his hand at publishing which he described to friends as the "Intelligent Young Man’s Guide to Capitalism".

Captain Atom was one of the few original Australian comic heroes to have his own merchandising and fan club.

When he died in Dublin's Meath Hospital at the age of 86, he left three books unfinished, his memoirs entitled Miracle Magazine, a work on "Australianism, as identified by press, politics and religion", and a biography of John Macarthur for which he had received a grant from the Literature Board of the Australia Council.

[1][8] Nora's Australian-born niece Meg Sordello, who had inherited Warnecke's papers and correspondence, donated them to the State Library of New South Wales where they have been held since 2003.
