An Englishman, John Osborn, who was living in Paris, invented it in 1828 (although it is believed the Romans had a similar dish called garum made from fermented fish). He created the tart spread from a blend of anchovies, butter, exotic herbs and spices, and named it Patum Peperium - a Greek and Latin etymological mix crudely meaning a paste of peppers. (The phrase Gentleman’s Relish was not incorporated into the name until the early 20th century. According to the company, the paste was so closely identified with the gentry, that people asked for Patum Peperium, adding, “You know, the gentleman’s relish”.)
