Who painted this painting?

Dogs Playing Poker, by Cassius Marcellus Coolidge, refers collectively to an 1894 painting, a 1903 series of sixteen oil paintings commissioned by Brown & Bigelow to advertise cigars, and a 1910 painting. All eighteen paintings in the overall series feature anthropomorphized dogs, but the eleven in which dogs are seated around a card table have become well known in the United States as examples of kitsch art in home decoration.
