Neponsit Beach Hospital for Children opened on April 16, 1915.
Neponsit Hospital was operated by the Bellevue and Allied Hospitals organization, a city agency which also operated Bellevue Hospital in Manhattan.
It replaced Sea Breeze Hospital, also operated by the Association, with children from Sea Breeze transferred to Neponsit.
Upon opening, the hospital was subject to odors and fumes from waste disposal operations on nearby Barren Island (now Floyd Bennett Field).

In the 1930s and early 1940s, the hospital was expanded as a Works Progress Administration (WPA) project, adding the nurses' residence and power plant.
The expansion was first announced in November 1929 by city hospitals commissioner Dr. William Schroeder, Jr. The project was intended to double the patient capacity of the facility.
In June 1931, an appropriation of $300,000 was made by the Board of Estimate for the nurses' home.
In December 1933, the city applied for a loan to fund the project.
Sketches for the murals were approved as part of the Federal Art Project in October 1935.
The first contract was awarded in December 1935, for the power plant.
The contract for the nurses' residence was awarded in 1938.
In addition, the WPA planned to plant 800 trees and create gardens on the grounds of the hospital, and add a 10-foot (3.0 m) high, 1,000-foot (300 m) sea wall.
The power plant was completed in 1939, and work on the nurses' residence began shortly afterwards.
The nurses' residence was completed in February 1941.

The hospital was closed temporarily on January 7, 1943 to conserve fuel during World War II.
Also during the war, the fence separating Riis Park from the hospital grounds was erected.
The hospital was reopened on March 1, 1945, after the United States Public Health Service began leasing it to treat servicemen with tuberculosis.
Following the war, the Public Health Service continued to use the hospital for veterans of the war.
After short extensions of the lease, it was returned to the city in 1950.
