Jean-François Rousseau
Jean-François Xavier Rousseau (16 October 1738 – 12 May 1808) was a French diplomat and orientalist, nicknamed “Rousseau of Persia.” He was born in Isfahan, Iran, and was the son of Jacques Rousseau, a Geneva-born watchmaker and diplomat, and Reine de l’Estoile.
In 1757 Rousseau became deputy director of the French East India Company in Basra, while carrying out diplomatic and trade missions in Persia. After the company’s director Claude Pirault died, Rousseau took over his duties (but not his title) and worked to defend French interests, negotiate Persian-Ottoman relations, and protect the rights of French residents.
In 1772 he married Anne-Marie Sahid, daughter of the Isfahan-born interpreter Joseph Sahid. They returned to France at the end of 1780, where Rousseau was appointed consul at Basra and then sent back to the field in 1782. He was accompanied by the botanist André Michaux, and in Aleppo joined abbé Pierre-Joseph de Beauchamp, an astronomer and vicar general of Baghdad. The three traveled by caravan from Aleppo to Baghdad in September and October 1782.
From 1783 Rousseau also served as consul in Baghdad, a post previously attached to Basra. He spoke seven languages—Arabic, Persian, Turkish, Armenian, Portuguese, Italian, and English—and was a major orientalist.
His son Joseph succeeded him as consul at Basra in 1805, later becoming consul-general at Aleppo and to the Tripoli Eyalet.
