Augustus Henry Keane (1833–1912) was an Irish Roman Catholic journalist and linguist, known for his ethnological writings.
Keane was editor of the Glasgow Free Press from 1862. He and his deputy Peter McCorry turned the first Scottish Catholic newspaper into a campaigning sheet, setting the Irish priests against the Scottish priests, and in particular the vicars-apostolic. The paper supported the nationalist Patrick Lavelle,  who used its pages to attack Paul Cullen.  John Murdoch, the Vicar Apostolic of the Western District was another particular target, the background being the increasing number of Irish Catholic priests in Scotland, and an increasing Irish immigrant population.  Keane and McCorry found themselves in court proceedings. 
The policy of the Glasgow Free Press under Keane and then McCorry had only short-term direct effects, and the paper was shut down after the intervention by Cardinal Manning towards the end of the 1860s; but the divisions it revealed have been taken as important in the move towards restoring the Scottish Catholic hierarchy, which occurred in 1878. Keane may have drifted from the Catholic faith in later life. 
Linguist, geographer, ethnologist
He studied in Germany and taught at Hameln ;  and became a linguist. He taught languages including Hindustani at the Hartley Institute, Southampton ; a chair of Hindustani was created for him at University College, London, in 1883, but he left it in 1885.  He then spent a period lecturing on ethnology at the University of Virginia in Charlotteville. 
Keane belonged to the "philological" group of British linguists, with Richard Garnett, Thomas Hewitt Key, Isaac Taylor, John Horne Tooke and Hensleigh Wedgwood.  He began attending meetings of the a Royal Anthropological Institute in 1879, read papers there, and became a Fellow, serving as vice-president. He was granted a Civil List pension in 1897.  Keane was a Fellow of the Royal Geographical Society.
Keane's racial theories were published first in Nature in 1879–81. He affirmed the specific unity of human beings in his 1896 text Ethnology , even if his views had some other implications. He produced racial typologies, in his expository writings; they were more systematic than those of John George Wood and Robert Brown, and were intended for rote learning. 
Keane was out of step with the anthropology of the time, preferring linguistic data to that of physical anthropology and came to occupy a marginal position in the emerging scientific discipline.  On the other hand, his efforts at popularising anthropology were praised by Sir Harry Johnston. 
Keane's views were invoked by F. W. Bell in South Africa from 1908, with those of Robert Bennett Bean, and played a part in the move of the Transvaal Native Affairs Society towards a segregationist position.  He was known for his sympathies displayed in The Boer States (1900), in which he attributed the long-term issue behind the Boer Wars to the attitude of Lord Glenelg in the 1830s.  The stance taken by Keane, who has been described as a "virulent racist", was conveyed in person when he addressed the Transvaal Native Affairs Society in September 1909. He cited Robert Wilson Shufeldt of Virginia, author of The Negro a Menace to American Civilization (1907), aiding the Bell faction against the moderates around Howard Pim.
