William Ashley 'Billy' Sunday (November 19 1862 - November 6 1935) was a popular outfielder in baseball's National League from 1883 to 1890 who later became the most celebrated and influential American evangelist during the first two decades of the 20th century. Known for his colloquial sermons and frenetic delivery Sunday held campaigns in America's largest cities and attracted the largest crowds of any evangelist before the advent of electronic sound systems. In addition Sunday was a strong supporter of Prohibition and his preaching likely played a role in the adoption of the Eighteenth Amendment in 1919.
