Morris relocated to the Peruvian capital, Lima, with his Peruvian wife and three children in 1915. A year later, he opened a saloon—Morris' Bar—which became popular with both the Peruvian upper class and English-speaking foreigners.[1][2][23] Morris, who often experimented with new drinks, developed the pisco sour as a variant of the whiskey sour.[1] Chilean historian Gonzalo Vial Correa also attributes the pisco sour's invention to Gringo Morris from the Peruvian Morris Bar, but with the minor difference of naming him William Morris.[24]
