In January 1934, newly elected Mayor Fiorello La Guardia appointed Robert Moses as the commissioner of the New York City Department of Parks (NYC Parks), a new organization that eliminated borough park commissioners. Moses would remain commissioner for the next twenty-six years, leaving significant impacts on the city's parks. Moses used federal monies made available to relieve Depression-era unemployment, and this resulted in a boom in construction at Prospect Park. The Prospect Park Zoo opened in 1935 on the east side of the park, replacing the former Menagerie. The Bandshell and five playgrounds were also constructed toward the end of the 1930s. In addition, the Carousel was opened in 1949 as a gift from the foundation of the late philanthropist Michael Friedsam. Moses also enacted new policies at the park, including a ban on sheep grazing at the Long Meadow.
