This Bushwick park occupies a full city block, bounded by Knickerbocker and Wilson Avenues and Halsey and Weirfield Streets. It has not been confirmed how Irving Square Park got its name; however, the name of one of the bordering streets may offer a clue. Beloved American writer Washington Irving (1783-1859) penned A History of New York (1809) under the pseudonym Diedrich Knickerbocker. The word knickerbocker has come to mean a descendant of the Dutch settlers of New York, but it also refers to full breeches gathered and banded just below the knee, or long bloomers worn as underwear (also knickers). A more recent use of the word is the New York Knickerbockers basketball team.
