Déjacque came from Jersey to New York in the spring of 1854, so the help wanted listing would have been soon after he arrived. The conflict over “La question révolutionnaire” was in 1854. The Association Internationale was formed in 1855, the same year that Claude Pelletier arrived in New York. And then Déjacque was in New Orleans for much of the period 1855–58. Le Libertaire was launched in June, 1858.

Mr. Joseph Déjacques, [sic] who lived, successively, in New York and New Orleans some years ago, and who, during his stay in America, published Le Libertaire and Les Lazaréennes, a newspaper and poems with a great boldness of style and a remarkable plebeian flair, died at Bicêtre, a lunatic asylum close to Paris, on November 18, 1865.
