Johnnie Walker
Originally known as Walker's Kilmarnock Whisky, the Johnnie Walker brand is a legacy left by John "Johnnie" Walker after he started to sell whisky in his grocer's shop in Ayrshire, Scotland. The brand became popular, but after Walker's death in 1857 it was his son Alexander Walker and grandson Alexander Walker II who were largely responsible for establishing the scotch as a popular brand. Under John Walker, whisky sales represented eight percent of the firm's income; by the time Alexander was ready to pass on the company to his own sons, that figure had increased to between 90 and 95 percent.
