Born the son of a Polish count, de Gurowski’s strong political opinions led to his expulsion from the Gymnasia of Warsaw and Kalisz, and later led to his imprisonment. His estates were confiscated because of his objections to Russian influence in the region. At the University of Berlin he studied philosophy under Hegel and later graduated from the University of Heidelberg in 1823. In Paris he studied with Charles Fourier, working on the notion of Pan-slavism which he developed in his book on the subject La Verite sur la Russie (1835).
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.
