Charles Gilbert-Martin, born August 26, 1839 in Gironde and died July 21, 1905 in St Thomas de Coniac, was a French caricaturist and journalist.

On May 19, 1867, he founded The PhilosopherEditor-in-chief of this satirical magazine, he produced most of the caricatures, alongside the painter Jean-Paul Laurens, who mainly drew scenes of morality. The Philosopher will only have 33 issues due to censorship and a court decision, rendered in January 1868, which condemns Gilbert-Martin to a fine of 200 francs and two months of detention in Sainte-Pélagie. Another satirical newspaper publishing drawings by the Girondin caricaturist, The Cockchafer was in turn hit by a conviction a few months later. Gilbert-Martin, who also collaborated on The Road by Jules Vallès, is in fact a republican opposed to the Second Empire.

After the Revolution of September 4, 1870, Gilbert-Martin was attached for a few months to the Ministry of the Interior, then entrusted to Gambetta, and worked with the delegation of the government of national defense in Tours. He then joined the Army of the North commanded by Faidherbe. A staff captain, he was promoted to the rank of Squadron Leader during the last months of the war against Germany.
