Purley Albert Baker (1858 – 1924) was an ordained Methodist minister who strongly opposed any consumption of beverage alcohol and was superintendent of the Ohio Anti-Saloon League. He became head of the national Anti-Saloon League in 1903 and five years later created the League's Industrial Relations Department to promote the idea that imposing prohibition would be a good business investment. He raised large sums of money to create a major information campaign, an important component of which was to demonize the producers of alcoholic beverages.
