Charles Boner (1815–1870) was an English travel writer, poet and translator.
He was the second child and only son of Charles Boner, of Bath, Somerset, who died at Twickenham, 14 Aug. 1833, and was born at Weston, near Bath, 29 April 1815. He was educated at Bath from 1825 to 1827, and then at Tiverton grammar school from 1827 to 1829. From 1831 to 1837 he was tutor to the two elder sons of John Constable the painter.
After his mother's death in 1839, Boner accepted an invitation from August, Freiherr von Dörnberg to reside with him in Germany. Some time later, having learned German, he accompanied the baron to Regensburg, where he had the offer of a post in the family of Maximilian Karl, 6th Prince of Thurn and Taxis. Boner became a lifelong friend of the prince, mixed in society, and spent twenty years in the family household at Regensburg. He visited William Wordsworth at Grasmere in 1844; and in 1845 he made the acquaintance of Mary Russell Mitford, with whom he carried on a literary correspondence for ten years.
In 1860 Boner left Regensburg and made Munich his home. His daughter Marie was married, 27 February 1865, to Theodor Horschelt the painter. As special correspondent of The Daily News, he went to Vienna in August 1865, his time with the paper lasting from the time when the treaty of commerce between England and Austria was arranged until the conclusion of the Seven Weeks' War. In 1867 Boner went to Salzburg to be present at the meeting of Napoleon III and Franz Joseph I of Austria, and wrote a description of the scene. He also visited Trieste, where he attended the funeral of Maximilian I of Mexico. He died in the house of his son-in-law Horschelt, 5 Louisenstrasse, Munich, 9 April 1870.
