No relation to Julius Caesar or indeed any classical Roman - the Caesar salad is named after Cesare Cardini, the Italian-born Tijuana restauranteur and hotelier who allegedly developed the recipe during the Prohibition-era Tijuana boom. I say "allegedly" because a number of other people have claimed Cardini lifted the recipe from them, either exactly as he popularized it or in some undeveloped form, eg the "Aviator salad."
