Obadiah Poundage was the pen-name of a London brewer of the 18th century who published a letter in the London Chronicle on November 4, 1760 arguing for a rise in the price of beer. The letter was reprinted in various journals, including the Gentleman's Magazine and The Gazetteer, and has since been used by beer historians for the basis of information about porter.
