Martin Bon Louis Henri (February 20, 1810 - 1883), French historian, was born at Saint-Quentin (Aisne), where his father was a judge. Trained as a notary, he followed this profession for some time but having achieved success with an historical romance, Wolfthurm (1830), he applied himself to historical research. Becoming associated with Paul Lacroix (Le Bibliophile Jacob), he planned with him a history of France, to consist of excerpts from the chief chroniclers and historians, with original matter filling up gaps in the continuity. The first volume, which appeared in 1833, encouraged the author to make the work his own, and his Histoire de France , in fifteen volumes (1833-1836), was the result. This magnum opus, rewritten and further elaborated (4th ed., 16 vols. and index, 1861-1865) gained for the author in 1856 the first prize of the Academy, and in 1869 the grand biennial prize of 20,000 francs. A popular abridgment in seven volumes was published in 1867. This, together with the continuation, Histoire de France depuis (1789) jusqud nosjours (6 vols. 1878-1883), gives a complete history of France, and superseded Sismondi 's Histoire des Français.

This work is in parts defective; Martin's descriptions of the Gauls are based rather on romance than on history, and in this respect he was too much under the influence of Jean Reynaud and his cosmogonic philosophy. However he gave a great impetus to Celtic and anthropological studies. His knowledge of the middle ages is inadequate, and his criticisms are not discriminating. As a free-thinking republican, his prejudices often biassed his judgment on the political and religious history of the ancient regime. The last six volumes, devoted to the 17th and 18th centuries, are superior to the earlier ones. Martin sat in the assemble nationale as deputy for Aisne in 1871, and was elected life senator in 1878, but he left no mark as a politician. He died in Paris on the 4th of December 1883.

Among his minor works may be mentioned: Dela France, de son genie et de ses destinies (1847); Daniel Manisf (1860), La Russie et l'Europe (1866); Etudes darchiologie celtique (1872); Les Napoleon el les fronties de la France (1874).
