New York culture bloomed in the first half of the 19th century: in 1809 Washington Irving wrote the satirical "A History of New York" under the pen name Diedrich Knickerbocker, and in 1819 he based "Rip Van Winkle" and "The Legend of Sleepy Hollow" in Hudson Valley towns. Thomas Cole's Hudson River School was established in the 1830s by showcasing dramatic landscapes of the Hudson Valley. The first baseball teams formed in New York City in the 1840s, including the New York Knickerbockers. Professional baseball later located its Hall of Fame in Cooperstown. Saratoga Race Course, an annual summer attraction in Saratoga Springs, opened in 1847.
