Clement Clarke Moore (1779-1863) was the great-great-great grandson of Reverend Moore. Born in New York City, Clement spent much of his boyhood and youth at the family estate in Newtown. He was tutored at home by his father and graduated from Columbia College with a B.A. in 1798, an M.A. in 1801, and an honorary LL.D.
Moore is best known as the inspired author of the delightful children’s poem, "A Visit from St. Nicholas." He composed the poem for his wife Catherine Elizabeth Taylor Moore and their children in 1822. A family friend had the poem published anonymously in the Troy Sentinel the following year. With subsequent publication in newspapers, magazines, and illustrated editions, the poem became a classic popularly known as "The Night before Christmas." Moore died in Newport, Rhode Island in 1863.
Around the turn of the century, most of the Moore estate was divided into building lots and sold at auction. The site of the homestead, however, remained in the family until the Board of Transportation acquired it during the construction of the Independent Subway in 1930. The buildings were razed in 1933. Soon after Parks acquired this property from Transportation in 1954, plans were drawn up for a new playground, with play equipment and athletic facilities for children.
