In 1904, the successful German-Jewish banker Felix M. Warburg (1871–1937) purchased large tracts of land to build his "Woodlands" estate in Hartsdale, a summer home next to the country club where he and his wife Frieda Schiff Warburg (1876–1958) spent considerable time. The estate would later become an important site in the history of modern American ballet, when on June 10, 1934, their son Edward M. M. Warburg (1908–1992) helped produce the first American performance of George Balanchine's masterpiece "Serenade". In keeping with the family's philanthropic efforts, Frieda Schiff Warburg, on her death in 1958, bequeathed a remaining to the town of Greenburgh to build a public school. These are now the home of the Greenburgh Central School District (formerly called Greenburgh Central 7 School District) and Woodlands High School. The main Warburg mansion currently serves as the school district headquarters, but other remnants from the original estate grounds can still be seen standing in the surrounding woods and neighboring streets. The Warburg family's New York City home would later be donated to become the Jewish Museum of New York.
