Louis Étienne Arthur Dubreuil, vicomte de La Guéronnière

Louis Étienne Arthur du Breuil, vicomte de La Guéronnière (1816 – 23 December 1875) was a French politician and aristocrat, the member of a notable Poitou family.

Although from early on connected with Legitimism, he became closely associated with the Republican Alphonse de Lamartine, to whose paper, Le Bien Public, he was a principal contributor.

[1] A character sketch of Louis-Napoléon Bonaparte in this journal caused differences with Lamartine, and La Guéronnière became more and more closely identified with the policy of the prince-president.

[1] His elder brother, Alfred du Breuil Helion, comte de La Guéronnière (1810–1884), who remained faithful to the Legitimist party, was also a well-known writer and journalist.

He was consistent in his opposition to the July Monarchy and the Empire, but in a series of books on the Franco-Prussian War of 1870–1871 showed a more favorable attitude to the Third French Republic.
