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).
Born in England in 1811, Thomas Blades (Bladies) de Walden made his first appearance on the English stage in 1841, then traveled to New York for his premier on the American stage at Park theatre in 1844 (Wilson and Fiske 158). Identified by William Winter as a regular at Pfaff’s during the Bohemian days, de Walden was active in the New York stage community as both an actor and a playwright (Old Friends 88). Mark Lause also labels de Walden as one of the frequent actors who inhabited the vault at Pfaff’s (60).
Born in Philadelphia, PA in September 1835, Rose Eytinge made her first appearance as an amateur actress in Brooklyn at the age of seventeen (Wilson and Fiske 396). Her first professional appearance was as Melanie in "The Old Guard" in a dramatic stock company in Syracuse, NY under the management of Geary Hough. She soon became "the leading juvenile woman" in the company but quickly moved on to her second professional acting engagement as the leading lady at the Green Street Theatre in Albany, NY (Eytinge 8).
Best know for his portrayal of Asa Trenchard in Our American Cousin and Rip Van Winkle in Rip Van Winkle, Joseph Jefferson was one of the most popular comedians of his time. Born February 20, 1829 in Philadelphia, Jefferson was the son of actors and was introduced to the stage as a child. Jefferson made his adult debut in New York in 1849 at the age of twenty. His early New York successes led to a tour of the South and theatrical engagements in Baltimore and Philadelphia.
A former teacher, Charles Bailey Seymour moved from London to New York City in 1849. In New York, he began working as the dramatic and musical editor for the New York Times. In 1858, Seymour published the book Self-Made Men.
