Pommes Anna is a famous French preparation of white potatoes, borne in the mid 19th century. The story goes that the dish was named after Anna Deslions, a well-known Parisian courtesan, who frequented Café Anglais where chef Adolphe Dugléré invented the dish to honor her (and the wealthy clientele that she brought into the popular restaurant).
The idea of naming food after celebrities appears to be a time-honored tradition. Some examples: Beef Wellington was named after the Duke of Wellington (in celebration of his victory during the Battle of Waterloo in 1815), Pizza Margherita was named after Queen Margherita, Beef Carpaccio is named in honor of painter Vittore Carpaccio (who worked with vibrant reds), and who could forget the Arnold Palmer?
At other times, the food itself turns folks into celebrities: Caesar salad is not named after Julius Caesar but Caesar Cardini, an Italian immigrant who invented the salad in 1924 while living in Tijuana, Mexico; and nachos are purportedly the invention of Ignacio Anaya, a boy who in 1943 whipped up the dish to feed some hungry soldiers in Piedras Negras, Mexico.
