Joseph Roux (1725–1793) was the patriarch of a family of instrument makers, hydrographers and marine artists, all living in Marseilles in the late eighteenth century. He was a highly successful maritime chartmaker, publishing a book of harbour charts which was reprinted well into the nineteenth century: a copy was used on the HMS Victory by Horatio Nelson. Roux was appointed royal hydrographer in the mid-eighteenth century.
There are octants by Roux in the Museum of America and the Sea, Connecticut, the Stewart Museum, Montreal, and the Mariner’s Musem, Virginia.
