North and South Brother Islands

The remains of Riverside Hospital on North Brother Island, 2006.

North and South Brother Islands are a pair of small islands located in New York City's East River between the Bronx and Rikers Island. North Brother Island was once the site of a hospital, but is now uninhabited and designated as a bird sanctuary. Until 1964, South Brother Island was part of Queens County, but it is now part of Bronx County.[1] It had long been privately owned, but it was purchased by the city in 2007.

According to the New York City Parks Department, North Brother Island has about 20 acres (8.1 ha) of land,[2] and South Brother Island is about 6 acres (2.4 ha).[3]

Bodies from the General Slocum wash ashore on North Brother Island, 1904.

Both North Brother Island and South Brother Island were claimed by the Dutch West India Company in 1614 and both were originally named "De Gesellen", translated as "the companions" in English.[4]

North Brother Island

The northern of the islands was uninhabited until 1885, when Riverside Hospital moved there from Blackwell's Island (now known as Roosevelt Island). Riverside Hospital was founded in the 1850s as the Smallpox Hospital to treat and isolate victims of that disease. Its mission eventually expanded to other quarantinable diseases.

The island was the site of the wreck of the General Slocum, a steamship which burned on June 15, 1904. Over 1,000 people died either from the fire on board the ship or from drowning before the ship was beached on the island's shores.[5]

Mary Mallon, also known as Typhoid Mary, was confined to the island for over two decades until she died there in 1938.[6][7] The hospital closed shortly thereafter.

Following World War II, the island housed war veterans who were students at local colleges, along with their families. After the nationwide housing shortage abated, the island was once again abandoned until the 1950s, when a center opened to treat adolescent drug addicts. The facility claimed to be the first to offer treatment, rehabilitation, and education facilities to young drug offenders. Heroin addicts were confined to this island and locked in a room until they were clean. Many of them believed they were being held against their will. By the early 1960s widespread staff corruption and patient recidivism forced the facility to close.

Now a bird sanctuary, the island is currently abandoned and off-limits to the public. Most of the original hospitals' buildings still stand, but are heavily deteriorated and in danger of collapse, and a dense forest conceals the ruined hospital buildings. In October 2014, New York City Council member Mark Levine, Chair of the City Council's Parks Committee, led a delegation to visit the island,[8] and declared his desire afterwards to open the island for limited "light-touch, environmentally sensitive" public access.[9]

South Brother Island

Jacob Ruppert, a brewery magnate and early owner of the New York Yankees, had a summer house on the island that burned down in 1909.[4] No one has lived on the island since then, and there are no structures extant. Ruppert owned the island until the late 1930s, and in 1944 it was purchased by John Gerosa, president of the Metropolitan Roofing Supply Company, who had wanted to construct a never-built summer retreat for his workers on the island.

In 1975, the City sold South Brother Island to Hampton Scows Inc., a Long Island investment company, for $10.[4][10] Hampton Scows paid property taxes every year but did not develop the island.

In November 2007, the island was purchased in a complicated transaction in which $2 million of Federal grant money from the

In popular culture

On South Brother Island, dense brush supports a major nesting colony of several species of birds, notably black-crowned night heron, great egret, snowy egret, and double-crested cormorant. New York City Audubon has monitored nesting colonies on the island for over twenty years.[13][14]

From the 1980s through the early 2000s, North Brother Island supported one of the area's largest nesting colonies of black-crowned night heron. However as of 2008 this species has abandoned the island for unknown reasons.[12] Barn swallows use the abandoned structures for nesting, and can be seen flying over the island.
