History

Welfare Island

1969

Welfare Island in 1969 was a shell of its former self. Many of its institutions that buzzed with life had dispersed across the city, leaving much of the Island behind to decay. The large amount of underutilized land presented a canvas for ideas on how it could be best used. Mayor John V. Lindsay would utilize the NYS Urban Development Corporation, established under Governor Nelson Rockefeller in 1968, to put forward a plan to redevelop the Island. Beginning in 1967, the Welfare Island Planning and Development Committee and Philip Johnson & John Burgee Architects would undergo a two-year process to thoroughly document Welfare Island's condition and prepare a proposal for its redevelopment. The surveying that took place was critical in the understanding of Welfare Island's history and how to maximize the Island's potential as New York's next neighborhood.

Smallpox Hospital

Opening as a quarantine hospital, the Smallpox Hospital aided in slowing the spread of the disease across the city. With the increase of people vaccinated against smallpox, the hospital became obsolete and was absorbed into the City Hospital, becoming a nursing school. The original structure saw three additions over its lifetime. The condition of the Smallpox Hospital in 1969 was abysmal but was deemed worth preservation.

Strecker Laboratory

Designed in the Romanesque style, the Strecker Laboratory was the first institution in the nation specifically for pathological and bacteriological research. The laboratory saw many important experiments that contributed greatly to the medical field. Being a part of City Hospital, it shuttered with the remainder of the campus in 1957. The building was left to decay, and its condition was very poor in 1969. Despite this, the building was recommended for preservation.

City Hospital

City Hospital took in the city's sick and destitute population. Over its 120-year history, the hospital changed names four times, also being known as: Island Hospital, Charity Hospital, and Renwick Hospital. The hospital's final days were in 1957 when patients were relocated to the newer Elmhurst Medical Center. The campus quickly deteriorated after vacancy and by 1969 the buildings were showing accelerating signs of decay. The main hospital building, with its mansard roof, was noted for rehabilitation in the 1969 Island survey.

Roosevelt Island

2025

Breaking ground in 1971, and subsequently renamed in 1973, Roosevelt Island has taken on an entire new life as a community for 12,000 people. Outlined in a report titled "The Island Nobody Knows" (1968) by Philip Johnson and John Burgee, the Island was conceptualized as a revolutionary mixed-use housing model centered around pedestrianization. What was once a center for city institutions, has experienced a metamorphosis into a vibrant community, being one of the most diverse in all of New York City.

2025 marks the 50th year of residential occupation with the Island's first resident moving into their apartment in Island House on April 25th, 1975. The Roosevelt Island 50 Exhibit displays the Island's transition from the days of Welfare Island in 1969 to its existing condition as one of the most successful urban renewal projects to complete in the United States.

This installation was created in collaboration between the Roosevelt Island Historical Society and the Roosevelt Island Operating Corporation. All photos credited to the RIHS.

Four Freedoms Park

FDR Four Freedoms Park was designed by Louis Khan in 1974. Khan died shortly before revealing the updated plans for the park. Because of funding issues, this park languished for nearly four decades. Finally, being completed in 2012, the park frames the southern tip of the Island in Khan's original vision.

Southpoint Park

Southpoint Park utilizes the land of what once was City Hospital. Today, lush lawns and nature lined paths adorn the landscape. Here you can find the stabilized remains of the Smallpox Hospital and the rehabilitated Strecker Laboratory, which is now an MTA substation. The City Hospital administration building suffered extensive damage from a fire in 1994 and was demolished despite being considered for preservation.

Cornell Tech

In 2011, Mayor Bloomberg announced a partnership between the city and Cornell University that would bring a new tech campus to Roosevelt Island. Goldwater Memorial Hospital would be demolished in 2014 to prepare the land for the campus, which opened its first phase in 2017. The Graduate Hotel and Conference Center opened four years later in 2021. Phase II has not been announced as of now, and the land it will occupy is currently an interim park.
