Gen. Dean Ivan Lamb, an aviation pioneer and infamous soldier of fortune, discovered Pisco sours in the Morris Bar in 1922. He famously had one too many, and the wake of destruction from the ensuing brawl hastened his departure from Peru. "I never learned what the liquid was derived from, but from personal experience believe it a triple distillation of nitroglycerin," he later recalled in his memoir, "The incurable filibuster."
