Fettuccine Alfredo – Alfredo di Lelio, an early-20th century Italian chef who invented the dish for his wife in 1914–1920 at his Roman restaurant and popularized it among tourists.
Caesar salad – Caesar Cardini (1896–1956) or one of his associates created this salad at the restaurant of the Hotel Caesar in Tijuana.
Cobb Salad – Robert H. Cobb, owner of the Hollywood Brown Derby restaurant, who is said to have invented the salad as a late-night snack for himself in 1936–1937.
Graham crackers, Graham flour – Sylvester Graham, 19th-century American Presbyterian minister and proponent of a puritan lifestyle based on teetotalling, vegetarianism, and whole wheat.
Heath bar – the American "English toffee" bar is named for brothers Bayard and Everett Heath, Illinois confectioners who developed it in the 1920s and eventually turned the local favorite into a nationally popular candy bar.
Kaiser rolls – originally, rolls made by a Viennese baker in about 1487 for Emperor Frederick V, whose profile was stamped on top.
Margarita – there are many claims for the name of this tequila/lime/orange liqueur cocktail. Dallas socialite Margarita Samas said she invented it in 1948 for one of her Acapulco parties. Enrique Bastate Gutierrez claimed he invented it in Tijuana in the 1940s for Rita Hayworth. Hayworth's real name was Margarita Cansino, and another story connects the drink to her during an earlier time when she was dancing in Tijuana nightclubs under that name. Carlos Herrera said he created and named the cocktail in his Tijuana restaurant in 1938–1939 for Marjorie King. Ms. King was reportedly allergic to all alcohol except tequila, and had asked for something besides a straight shot. Around this same general time period, Nevada bartender Red Hinton said he'd named the cocktail after his girlfriend Margarita Mendez. Other stories exist.
Mary Janes – peanut butter and molasses candy bars developed by Charles N. Miller in 1914, and named after his favorite aunt.
Reuben sandwich – possibly Arnold Reuben, a New York restaurateur (1883–1970), created and named it c. 1914, or Reuben Kolakofsky (1874–1960) c. 1925 may have made it for a poker group gathered at his Omaha, Nebraska grocery.
Baby Ruth candy bar – most likely, Babe Ruth (1895–1948) was the inspiration for the name. Although the Curtiss Candy Co. has insisted from the beginning that the candy bar was named after a daughter of Grover Cleveland, Ruth Cleveland died in 1904 at the age of 12, while the Baby Ruth was introduced in 1921 right at a time when George Herman Ruth, Jr. had become a baseball superstar. It is interesting to note that very early versions of the wrapper offer a baseball glove for 79 cents. Babe Ruth's announced intent to sue the company is probably what drove and perpetuated the dubious cover story.
Salisbury steak – Dr. James H. Salisbury (1823–1905), early U.S. health food advocate, created this dish and advised his patients to eat it three times a day, while limiting their intake of "poisonous" vegetables and starches.
Sandwich – John Montagu, 4th Earl of Sandwich (1718–1792) did not invent the sandwich. Meat between slices of bread had been eaten long before him. But as the often-repeated story goes, his title name was applied to it c. 1762, after he frequently called for the easily-handled food while entertaining friends. Their card games then were not interrupted by the need for forks and such.
Tootsie Rolls – Clara "Tootsie" Hirshfield, the small daughter of Leo Hirshfield, developer of the first paper-wrapped penny candy, in New York, 1896.
