Emeric Essex Vidal (29 March 1791 – 7 May 1861) was an English watercolourist and naval officer. His opportunities for travel, his curiosity about local customs and human types, and his eye for the picturesque, led him to make paintings which are now historical resources. A landscape painter and a costumbrista, he was the first visual artist to leave records of the ordinary inhabitants of the newly emergent Argentina and Uruguay, including the first depictions of gauchos. He also left records of Canada, Brazil, the West Indies and St Helena, where he sketched the newly deceased Napoleon.
