<P> 1937 Cafe Royal Cocktail Book contains a recipe for a Picador using the same concentrations of tequila, triple sec and lime juice as a margarita . One of the earliest stories is of the margarita being invented in 1938 by Carlos "Danny" Herrera at his restaurant Rancho La Gloria, halfway between Tijuana and Rosarito, Mexico, created for customer and former Ziegfeld dancer Marjorie King, who was allergic to many spirits, but not to tequila . This story was related by Herrera and also by bartender Albert Hernandez, acknowledged for popularizing a margarita in San Diego after 1947, at the La Plaza restaurant in La Jolla . </P> <P> Another origin story of the margarita is that it was invented in October 1941, at Hussong's Cantina in Ensenada, Mexico, by bartender Don Carlos Orozco . One afternoon, Margarita Henkel, the daughter of the then German ambassador visited the cantina and Don Carlos who had been experimenting with drinks offered her one . The cocktail consisted of equal parts of tequila, Mexican orange liqueur called Controy (A.K.A. Naranja in the United States), and lime, shaken and served over ice in a salt - rimmed glass . As she was the first to try the drink, Don Carlos decided to name it after her and the "Margarita" was born . </P> <P> There are also claims that the margarita was first mixed in Juárez, Mexico at Tommy's Place Bar on July 4, 1942 by Francisco "Pancho" Morales . Morales later left bartending in Mexico to become a US citizen, where he worked as a milkman for 25 years . Mexico's official news agency Notimex and many experts have said Morales has the strongest claim to having invented the margarita . </P> <P> Others say the inventor was Dallas socialite Margarita Sames, when she concocted the drink for her guests at her Acapulco vacation home in 1948 . Tommy Hilton reportedly attended, bringing the drink back to the Hilton chain of hotels . However, Jose Cuervo was already running ad campaigns for the margarita three years earlier, in 1945, with the slogan, "Margarita: It's more than a girl's name ." According to Jose Cuervo, the cocktail was invented in 1938 by a bartender in honor of Mexican showgirl Rita de la Rosa . </P>
