Born in Massachusetts to a family of merchants and seamen, Clapp traveled to Paris to translate the socialist writings of Fourier. In Paris, Clapp abandoned his ardent sympathy for the temperance movement and embraced the leisurely café life of the city. Upon returning to New York in 1850, he sought to recreate this atmosphere, spending hours at Charlie Pfaff's beer cellar, drawing a crowd of journalists, painters, actors, and poets to cultivate an American Bohemia in which participants admired and discussed the work of Edgar Allan Poe, Charles Dickens, and Washington Irving (Martin 15-7).
While there is scant evidence that Mark Twain (Samuel Clemens) ever visited Pfaff's bar (only one source suggests that he did [Rawson 99]), he was connected to the Pfaff's bohemians in a number of ways.
Born in small-town New England, Charles Browne began his career as a young contributor to the Boston Carpet Bag, a humor magazine, and later at Cleveland’s The Plain Dealer he adopted the persona of circus showman Artemus Ward. As Ward, he began writing letters from this fictional character whose travels inspired social commentaries, satires, and burlesques.
